Before selecting facial products, which record entry most directly helps identify a risk of irritation or product incompatibility?
☐ A. Skin type and the makeup finish chosen at the previous appointment.
☐ B. Known reactions and the client's current skin-care products.
☐ C. The previous facial's duration and the client's preferred massage pressure.
☐ D. The client's usual moisturizer price range and preferred texture.
Show answer and explanation
Response:B
Final answer:Known reactions and the client's current skin-care products.
Record current skin-care products and previous reactions because those details help the cosmetologist assess product suitability during the consultation before applying anything to the client's skin.
Question 2
A permanent-wave lotion is described as thio-free. Which reducing ingredient could account for this classification?
☐ A. Ammonium thioglycolate.
☐ B. Glyceryl monothioglycolate.
☐ C. Hydrogen peroxide.
☐ D. Cysteamine hydrochloride.
Show answer and explanation
Response:D
Final answer:Cysteamine hydrochloride.
Cysteamine is a reducing ingredient used in certain thio-free permanent-wave systems. Hydrogen peroxide serves as an oxidizer in the referenced system, while both thioglycolate ingredients belong to thio chemistry.
Question 3
A technician needs information about a nail product's hazards, protective equipment, and first aid after a spill. Which source should be consulted?
☐ A. The product's advertising brochure.
☐ B. The salon's color-formula chart.
☐ C. The client's completed service record.
☐ D. The product's safety data sheet.
Show answer and explanation
Response:D
Final answer:The product's safety data sheet.
The safety data sheet describes chemical hazards and precautions. A color-formula chart and client service record serve other purposes, while advertising does not replace the product's safety information.
Question 4
Which facial muscle helps close the jaw during chewing?
☐ A. Frontalis.
☐ B. Masseter.
☐ C. Zygomaticus major.
☐ D. Orbicularis oculi.
Show answer and explanation
Response:B
Final answer:Masseter.
The masseter acts on the mandible to close the jaw during chewing, while the other muscles listed act mainly around the eyes, forehead, or corners of the mouth.
Question 5
A nail plate shows lifting from the nail bed and a sore area beneath it. Before applying an enhancement, what is appropriate?
☐ A. Remove any old enhancement and apply a new overlay to the separated plate.
☐ B. Complete a shorter enhancement after cleaning the visible separation.
☐ C. Change to a tip-and-wrap service to avoid liquid-and-powder application.
☐ D. Defer application and recommend appropriate evaluation.
Show answer and explanation
Response:D
Final answer:Defer application and recommend appropriate evaluation.
Defer the enhancement. Separation of the natural plate with soreness needs assessment, and changing the enhancement system or reducing its length does not resolve the underlying condition.
Question 6
An adhesive tape extension is still firmly bonded. What is the appropriate removal approach?
☐ A. Apply the approved remover at the bond, allow it to loosen, and release gently.
☐ B. Apply the usual rinse-out conditioner to the bond, then slide the tape away.
☐ C. Peel the tape back first, then apply remover to the adhesive left on the hair.
☐ D. Wet the attachment with shampoo and rinse before separating the tape.
Show answer and explanation
Response:A
Final answer:Apply the approved remover at the bond, allow it to loosen, and release gently.
Apply the extension system's approved bond remover before release, allowing the adhesive to loosen rather than peeling an intact bond and treating only the remaining residue.
Question 7
Two acid-labelled wave products give different test-curl directions for tinted hair. What should determine the procedure for the selected product?
☐ A. The test-curl rule from an unrelated alkaline product.
☐ B. Its specific directions for that hair condition.
☐ C. A single rule that all acid waves require dryer heat.
☐ D. The shortest processing time on the salon's shelf.
Show answer and explanation
Response:B
Final answer:Its specific directions for that hair condition.
Use the selected acid wave's directions for tinted hair because that formula's test-curl procedure and processing limits belong to its own instructions, and another product in the acid category may specify a different procedure for the same hair condition.
Question 8
A stylist repeatedly bends the wrist sharply while cutting at the client's shoulder. Which adjustment best addresses this ergonomic problem?
☐ A. Take brief hand rests while keeping the same working height.
☐ B. Move the elbow farther out while retaining the bent wrist position.
☐ C. Adjust the chair and working angle so the wrist can remain near neutral.
☐ D. Change to a longer blade while retaining the same hand and chair positions.
Show answer and explanation
Response:C
Final answer:Adjust the chair and working angle so the wrist can remain near neutral.
Change the working angle. Adjusting the client and tool position addresses the sustained wrist bend itself, whereas a break or blade change does not correct that posture when cutting resumes.
Question 9
Two clients use the same unprocessed comb. Which route of transmission does this create?
☐ A. Direct contact between the clients' scalps.
☐ B. Indirect contact through a contaminated article.
☐ C. Ingestion of contaminated food.
☐ D. Inhalation of an airborne chemical vapor.
Show answer and explanation
Response:B
Final answer:Indirect contact through a contaminated article.
A used comb can transmit organisms. Carrying organisms from one person's hair or scalp to another through that shared article is indirect contact, so the comb needs appropriate reprocessing between clients.
Question 10
Which device helps a cosmetologist inspect skin more closely during a basic facial analysis?
☐ A. A facial steamer.
☐ B. A skin-cleansing brush.
☐ C. A magnifying lamp.
☐ D. A wax warmer.
Show answer and explanation
Response:C
Final answer:A magnifying lamp.
A magnifying lamp enlarges and illuminates skin for closer observation during analysis, while the consultation remains necessary and any finding that needs diagnosis belongs with an appropriate medical professional.
Question 11
In a basic facial, why are surface makeup and soil removed before close skin analysis?
☐ A. Cleansing fixes the skin's moisture level before products are selected.
☐ B. Cleansing makes a consultation unnecessary once the skin is visible.
☐ C. Cleansing makes the lamp show deeper skin layers rather than the surface.
☐ D. Surface material can obscure the skin features being evaluated.
Show answer and explanation
Response:D
Final answer:Surface material can obscure the skin features being evaluated.
Makeup and soil can hide surface features. Cleansing permits closer observation for service planning, with the client's history and contraindication assessment still needed.
Question 12
A client asks for customized highlights painted freehand through selected sections. Which technique most directly matches this application description?
☐ A. A uniform root retouch.
☐ B. Balayage.
☐ C. A woven highlight pattern selected entirely with a tail comb.
☐ D. A single-process all-over color.
Show answer and explanation
Response:B
Final answer:Balayage.
Balayage uses freehand painting to customize highlight placement. The colorist selects a suitable color or lightener formula for the planned result and paints selected areas of the hair.
Question 13
A shampoo surfactant has a water-attracting end and an oil-attracting end. How does this structure help cleanse the hair?
☐ A. The oil-attracting end stays in water while the water-attracting end binds oil.
☐ B. The oil-attracting end associates with oily soil while the water-attracting end associates with water.
☐ C. Both ends form an oil film that prevents rinse water from contacting the soil.
☐ D. Both ends bind to the hair so oily soil can evaporate without rinsing.
Show answer and explanation
Response:B
Final answer:The oil-attracting end associates with oily soil while the water-attracting end associates with water.
The two ends have different affinities. The oil-attracting portion associates with oily soil and the water-attracting portion with water, helping disperse the soil for removal during rinsing.
Question 14
During nail preparation, which material may be gently removed from the nail plate without cutting the living proximal nail fold?
☐ A. Nonliving cuticle tissue adhering to the plate.
☐ B. The living fold protecting the nail base.
☐ C. The tissue beneath the free edge.
☐ D. The nail matrix beneath the fold.
Show answer and explanation
Response:A
Final answer:Nonliving cuticle tissue adhering to the plate.
Preserve the living nail fold. Gently remove only nonliving cuticle adhering to the nail plate during preparation, since cutting into the protective living proximal fold can injure it.
Question 15
A curling iron has product residue on its barrel. Before following its cleaning directions, what should the cosmetologist do?
☐ A. Unplug it and allow it to cool.
☐ B. Turn the heat up before applying cleaner.
☐ C. Wipe the barrel while it is hot to loosen residue.
☐ D. Immerse the powered tool in cleaning solution.
Show answer and explanation
Response:A
Final answer:Unplug it and allow it to cool.
Unplug the curling iron and let it cool before using the approved cleaning method, keeping its electrical parts out of liquid to reduce shock and burn hazards.
Question 16
A disinfectant label requires a cleaned surface to stay visibly wet for five minutes. The surface dries after two minutes. What is needed to complete disinfection?
☐ A. Count the remaining time while it is dry.
☐ B. Reduce the contact time for a smooth surface.
☐ C. Reapply as directed and provide the full uninterrupted wet contact time.
☐ D. Wipe it dry once the odor disappears.
Show answer and explanation
Response:C
Final answer:Reapply as directed and provide the full uninterrupted wet contact time.
The label requires five minutes of wet contact. A surface that dried after two minutes has not received that exposure, so reapply as directed and provide the complete required wet period.
Question 17
A colorist considers combining two finished hair-dye products even though their manufacturers do not authorize the combination. Which action is appropriate?
☐ A. Combine them after testing only one of the products.
☐ B. Use the processing time from whichever product acts faster.
☐ C. Combine them if both are labelled permanent color.
☐ D. Use a compatible system according to its directions.
Show answer and explanation
Response:D
Final answer:Use a compatible system according to its directions.
Use combinations authorized for the selected color system because an improvised mixture can change performance and hazards, and a negative patch test does not validate an otherwise unauthorized formula.
Question 18
A circulating pedicure basin looks clean, but debris is trapped behind its removable inlet screen. Why must the screen area also be cleaned?
☐ A. Clear water prevents organisms from reaching hidden surfaces.
☐ B. Nightly cleaning eliminates the need to clean between clients.
☐ C. Trapped material can support microbial growth in the circulation system.
☐ D. Disinfectant concentration makes prior debris removal unnecessary.
Show answer and explanation
Response:C
Final answer:Trapped material can support microbial growth in the circulation system.
Remove the screen and debris. Material retained beneath the screen can support biofilms, so the footspa needs the prescribed cleaning of these concealed areas before label-directed disinfection.
Question 19
A client's color-treated hair feels dry after washing, with no substantial buildup or identified scalp disorder. Which shampoo selection best fits the information available?
☐ A. A frequent clarifying routine selected for substantial product buildup.
☐ B. A medicated routine selected for a scalp disorder that has not been identified.
☐ C. A shampoo intended for dry, color-treated hair and the client's assessed needs.
☐ D. A deep-cleansing routine selected for an oily scalp despite the reported dryness.
Show answer and explanation
Response:C
Final answer:A shampoo intended for dry, color-treated hair and the client's assessed needs.
Choose for the assessed condition. A shampoo intended for dry, color-treated hair fits this client better than selecting a treatment for buildup, excess oil, or an unconfirmed scalp disorder.
Question 20
A stylist shapes damp hair into connected wave ridges with a comb, fingers, and waving lotion. Which wet-styling technique is being performed?
☐ A. A pin-curl set.
☐ B. A permanent chemical wave.
☐ C. Finger waving.
☐ D. A roller set.
Show answer and explanation
Response:C
Final answer:Finger waving.
Finger waving molds damp hair into connected ridges and troughs with a comb and fingers, producing a temporary style without the chemical change used in a permanent texture service.
Question 21
Which recommendation appropriately completes a daytime skin-care discussion about sun protection?
☐ A. Choose broad-spectrum SPF 30 sunscreen and rely on one morning application throughout a day spent swimming.
☐ B. Choose SPF 50 sunscreen without checking whether it is broad-spectrum.
☐ C. Choose broad-spectrum SPF 30 sunscreen and treat it as sufficient for all outdoor exposure.
☐ D. Choose suitable broad-spectrum SPF 30 or higher sunscreen with shade and protective clothing.
Show answer and explanation
Response:D
Final answer:Choose suitable broad-spectrum SPF 30 or higher sunscreen with shade and protective clothing.
Follow the reapplication directions. Broad-spectrum SPF 30 or higher matches AAD advice, but one morning application does not cover a day of swimming and sunscreen still works alongside shade and protective clothing.
Question 22
Which statement correctly describes glove use during a service with possible blood contact?
☐ A. Gloves supplement hand hygiene and need changing when contaminated.
☐ B. Gloves allow the same pair to be used on successive clients.
☐ C. Gloves replace washing after their removal.
☐ D. Gloves may be cleaned on the hands for reuse.
Show answer and explanation
Response:A
Final answer:Gloves supplement hand hygiene and need changing when contaminated.
Wash hands between clients. Gloves provide a barrier during appropriate tasks, but hands still need cleaning when gloves are removed because glove use alone does not complete hand hygiene.
Question 23
Every new subsection is directed to the same fixed guide instead of to the previously cut subsection. Which guide is being used?
☐ A. A stationary guide.
☐ B. A mobile cross-check.
☐ C. A natural part.
☐ D. A traveling guide.
Show answer and explanation
Response:A
Final answer:A stationary guide.
A stationary guide remains fixed as each new section is directed to it, whereas a traveling guide uses previously cut hair as the next guide while the work progresses.
Question 24
A reusable comb falls onto the floor during a service. What is the appropriate next action?
☐ A. Return it directly to the clean-tool drawer.
☐ B. Wipe it on the client's cape and continue.
☐ C. Replace it with a clean comb and reprocess the dropped one.
☐ D. Use only its opposite end for the rest of the haircut.
Show answer and explanation
Response:C
Final answer:Replace it with a clean comb and reprocess the dropped one.
Clean the comb first. A reusable comb that falls to the floor needs cleaning and the appropriate disinfection before reuse, with the required concentration and contact time followed.
Question 25
Within a vertical cutting subsection, what does the angle of the fingers most directly control?
☐ A. The line being cut within that subsection.
☐ B. The density of the hair at the scalp.
☐ C. The direction in which the entire section is moved to a guide.
☐ D. The elevation of the section away from the head.
Show answer and explanation
Response:A
Final answer:The line being cut within that subsection.
Finger angle sets the cutting line within the subsection. Elevation and overdirection also affect the overall shape, but they describe different aspects of how the hair is held.
Question 26
Which substance produced by sebaceous glands helps lubricate the scalp and hair?
☐ A. Sweat.
☐ B. Keratin.
☐ C. Melanin.
☐ D. Sebum.
Show answer and explanation
Response:D
Final answer:Sebum.
Sebaceous glands produce sebum, an oily material that helps lubricate and protect the scalp and hair. Sweat, pigment, and structural protein serve different functions.
Question 27
A technician wears an N95 respirator while filing nails. Which hazard is that respirator designed to filter, when fitted and used appropriately?
☐ A. Oxygen deficiency in an enclosed room.
☐ B. Every gas produced by heated cosmetics.
☐ C. All solvent vapors from nail products.
☐ D. Airborne particles such as filing dust.
Show answer and explanation
Response:D
Final answer:Airborne particles such as filing dust.
An N95 filters particles. It does not provide protection against solvent vapors or gases, so chemical exposure needs the controls and respiratory protection appropriate to that hazard.
Question 28
Two clients have strands of similar thickness, but one has substantially more hairs per square inch. Which characteristic differs?
☐ A. Individual strand texture.
☐ B. Hair color level.
☐ C. Density.
☐ D. Hair-growth stage of every follicle.
Show answer and explanation
Response:C
Final answer:Density.
Density refers to the amount of hair in an area, while texture refers to the thickness of an individual strand. Similar strand thickness can occur with quite different densities.
Question 29
Which control most directly captures nail-product vapor near the workstation before it spreads through the room?
☐ A. Properly maintained local exhaust ventilation.
☐ B. A fan directed from the workstation toward another client.
☐ C. A workstation enclosure without air extraction.
☐ D. A fan that circulates air without removing it.
Show answer and explanation
Response:A
Final answer:Properly maintained local exhaust ventilation.
Capture vapor at its source. Local exhaust draws contaminated air away before it spreads into the room, while an enclosure without air extraction provides no equivalent capture.
Question 30
Which reducing ingredient is commonly found in an alkaline permanent-wave lotion?
☐ A. Glyceryl thioglycolate.
☐ B. Ammonium thioglycolate.
☐ C. Sodium hydroxide.
☐ D. Hydrogen peroxide.
Show answer and explanation
Response:B
Final answer:Ammonium thioglycolate.
Ammonium thioglycolate is an alkaline-wave reducer. It acts during the reducing stage, whereas the prescribed oxidizing neutralizer belongs to a later stage of the permanent-wave service.
Question 31
Before planning a thio texture service, which part of a client's history is especially relevant to preventing an incompatible overlap?
☐ A. The roller diameter used in the last wet set.
☐ B. Previous hydroxide relaxer treatment on the lengths.
☐ C. The position of the client's preferred part.
☐ D. The length removed at the last haircut.
Show answer and explanation
Response:B
Final answer:Previous hydroxide relaxer treatment on the lengths.
Identify the chemistry already present on the lengths before selecting a thio service, because previously hydroxide-relaxed hair can be incompatible with the planned treatment and vulnerable to damaging overlap.
Question 32
During complete removal of soak-off gel polish, some product remains firmly attached after the prescribed soak. What should the technician do?
☐ A. Use a manicure stick to lift the attached edges before another soak.
☐ B. Buff the remaining coating smooth and proceed to polishing with the residue in place.
☐ C. Replace the specified remover with warm soapy water for the remaining coating.
☐ D. Continue the approved removal process until it softens enough for gentle removal.
Show answer and explanation
Response:D
Final answer:Continue the approved removal process until it softens enough for gentle removal.
Allow the product to soften. Continue the specified removal process for firmly attached gel rather than lifting its edges first, leaving residue under new polish, or substituting ordinary washing for the directed remover.
Question 33
Which product-label description best supports selection for hospital-level disinfection of a pedicure basin?
☐ A. An EPA-registered sanitizer with directions for the basin but no hospital-disinfection use.
☐ B. An EPA-registered disinfectant whose directions cover soft furnishings rather than the basin.
☐ C. A scale remover with basin-cleaning directions and a general antibacterial advertising claim.
☐ D. An EPA-registered hospital disinfectant with directions applicable to the basin.
Show answer and explanation
Response:D
Final answer:An EPA-registered hospital disinfectant with directions applicable to the basin.
Check the registered use. The product must be an EPA-registered hospital disinfectant with applicable basin directions, since a sanitizer claim, an unrelated use, or antibacterial advertising is insufficient.
Question 34
After cleaning a removable dryer filter with water, what should happen before the filter is reinstalled and the dryer used?
☐ A. Allow all parts of the washed filter to dry completely before reinstalling it.
☐ B. Reinstall it while damp and run the dryer on cool to complete drying.
☐ C. Dry the outside of the filter and reinstall it while moisture remains inside.
☐ D. Fit the damp filter and postpone heat until the next client arrives.
Show answer and explanation
Response:A
Final answer:Allow all parts of the washed filter to dry completely before reinstalling it.
Dry the whole filter first. A dry outer surface does not establish that the washed part is ready for reinstallation, and running the dryer should not replace the prescribed complete drying step.
Question 35
Which information most directly helps assess both support and intended fullness when choosing a single- or double-sided tape-extension application?
☐ A. The client's natural density and the desired result.
☐ B. The extension's length and shade match.
☐ C. The client's target fullness and preferred maintenance interval.
☐ D. The attachment configuration used for a similar style on a different density.
Show answer and explanation
Response:A
Final answer:The client's natural density and the desired result.
Assess natural density and intended fullness. The supporting hair and desired blend guide selection, while a shade match or another client's attachment pattern does not establish suitable support.
Question 36
Which massage movement is characterized by controlled kneading and rolling of the tissue?
☐ A. Tapotement.
☐ B. Vibration.
☐ C. Petrissage.
☐ D. Effleurage.
Show answer and explanation
Response:C
Final answer:Petrissage.
Petrissage uses kneading and rolling movements. Effleurage glides over the surface, tapotement involves tapping, and vibration uses a shaking movement.
Question 37
A cream product must be removed from a shared jar for a facial. Which method helps prevent contaminating the remaining product?
☐ A. Dispense with an applicator reserved for this client, redipping it after skin contact.
☐ B. Use a gloved finger to collect more cream after the glove has touched the client's face.
☐ C. Transfer a portion with a clean spatula and keep client-used applicators out of the jar.
☐ D. Transfer a portion to a dish, then put any remaining client portion back in the jar.
Show answer and explanation
Response:C
Final answer:Transfer a portion with a clean spatula and keep client-used applicators out of the jar.
Dispense a separate portion. An applicator or glove that has touched the client's skin can contaminate the jar, and a leftover client portion should not be returned to the bulk supply.
Question 38
A nail technician breathes vapor released from an open solvent container. Which exposure route is involved?
☐ A. Inhalation.
☐ B. Ingestion.
☐ C. Injection.
☐ D. Skin absorption.
Show answer and explanation
Response:A
Final answer:Inhalation.
Vapor is breathed into the lungs. Breathing contaminated air is inhalation, one of the exposure routes a technician considers when reviewing a chemical product's hazards and controls.
Question 39
Why does a permanent-wave service often include the prescribed pre-service shampoo?
☐ A. Set the finished curl before the rods are placed.
☐ B. Remove surface debris that can interfere with the waving solution's access to the hair.
☐ C. Remove the neutralizer after processing.
☐ D. Restore disulfide bonds after the reducing lotion.
Show answer and explanation
Response:B
Final answer:Remove surface debris that can interfere with the waving solution's access to the hair.
The prescribed pre-perm shampoo removes surface material that could interfere with solution reaching the hair, but the service still needs consultation, appropriate product selection, and the required neutralization.
Question 40
Which system transports oxygen and nutrients to tissues through the blood?
☐ A. Skeletal system.
☐ B. Nervous system.
☐ C. Integumentary system.
☐ D. Circulatory system.
Show answer and explanation
Response:D
Final answer:Circulatory system.
The heart and blood vessels circulate blood that delivers oxygen and nutrients and carries waste away. This transport is the circulatory system's role.
Question 41
When preparing a natural nail for an enhancement, what is the purpose of gently removing surface shine with the specified fine abrasive?
☐ A. Prepare the bonding surface while preserving the nail plate's thickness.
☐ B. Thin the entire plate so the enhancement can penetrate it more deeply.
☐ C. Create deep grooves so a thicker enhancement can lock into the plate.
☐ D. Remove the upper plate layers to make them absorb more liquid product.
Show answer and explanation
Response:A
Final answer:Prepare the bonding surface while preserving the nail plate's thickness.
Preserve the natural plate. Gentle removal of surface shine prepares the bonding area without the unnecessary thinning or deep grooves proposed by the other methods.
Question 42
What is the purpose of placing an appropriate clean towel or neck barrier between the client's skin and the shampoo cape?
☐ A. Replace cleaning and disinfection of the bowl.
☐ B. Protect the neck from direct cape contact and moisture.
☐ C. Increase the hair's porosity before cleansing.
☐ D. Replace the need to launder a used cape.
Show answer and explanation
Response:B
Final answer:Protect the neck from direct cape contact and moisture.
Place the clean barrier between the skin and cape to protect the neck from direct contact and moisture, while still cleaning equipment and laundering used fabric as required.
Question 43
A client with dry, sensitive skin asks for a moisturizer. Which ingredient category warrants particular caution because it can cause irritation?
☐ A. A fragrance-free cream formulation.
☐ B. Added fragrance.
☐ C. Moisturizing oils suited to the client's skin.
☐ D. Water used as the formula's solvent.
Show answer and explanation
Response:B
Final answer:Added fragrance.
Fragrance can irritate sensitive or dry skin. Review the product with the client's history in mind when choosing suitable fragrance-free care for this client.
Question 44
A color system specifies one part color to two parts compatible developer. How much developer is needed for 30 mL of color?
☐ A. 90 mL.
☐ B. 15 mL.
☐ C. 60 mL.
☐ D. 30 mL.
Show answer and explanation
Response:C
Final answer:60 mL.
Double the color quantity. For this stated one-to-two ratio, 30 mL of color requires 60 mL of the specified compatible developer, obtained by multiplying 30 by two.
Question 45
Which statement distinguishes a hydroxide relaxer's neutralizing shampoo from a thio system's oxidizing neutralizer?
☐ A. The shampoo reforms disulfide bonds, while the oxidizer mainly restores the scalp's pH.
☐ B. Both products restore pH but leave reduced disulfide bonds unchanged.
☐ C. The shampoo removes alkaline residue and restores pH, while the oxidizer helps reform disulfide bonds.
☐ D. Both products reform disulfide bonds by supplying the original reducing ingredient.
Show answer and explanation
Response:C
Final answer:The shampoo removes alkaline residue and restores pH, while the oxidizer helps reform disulfide bonds.
Distinguish the chemical functions. Hydroxide neutralizing shampoo removes alkaline residue and restores pH, while the thio system's prescribed oxidizing neutralizer helps reform bonds altered during reduction.
Question 46
A client straightens the fingers during a hand service. Many of the long muscles producing this movement are located in which region?
☐ A. Upper arm.
☐ B. Palm alone.
☐ C. Shoulder.
☐ D. Forearm.
Show answer and explanation
Response:D
Final answer:Forearm.
Many long extrinsic finger muscles lie in the forearm and act through tendons extending into the hand, allowing finger joints to move even though the muscle bellies are farther up the limb.
Question 47
A cosmetic rinse has a measured pH of 4.5. How is it classified on the pH scale?
☐ A. Neither acidic nor alkaline.
☐ B. Acidic.
☐ C. Neutral.
☐ D. Alkaline.
Show answer and explanation
Response:B
Final answer:Acidic.
Values below pH 7 are acidic. A pH of 4.5 is below that neutral point, regardless of the product's color or fragrance.
Question 48
Which body system carries messages about pressure and temperature from the skin toward the brain?
☐ A. Nervous system.
☐ B. Reproductive system.
☐ C. Digestive system.
☐ D. Skeletal system.
Show answer and explanation
Response:A
Final answer:Nervous system.
Sensory nerves carry information about skin pressure and temperature toward the central nervous system, allowing the client to perceive the contact and changing water temperature during a service.
Question 49
A lightened section has an unwanted yellow tone. Which complementary tone is used to counteract yellow?
☐ A. Red.
☐ B. Violet.
☐ C. Orange.
☐ D. Yellow.
Show answer and explanation
Response:B
Final answer:Violet.
Yellow and violet are complementary. A colorist uses an appropriate violet tone to counteract unwanted yellow, choosing the final formula for the lightened hair's level and condition.
Question 50
Which completed color-service record best supports evaluating the actual formula and process at the next appointment?
☐ A. Natural level, target shade, selected product line, and service price.
☐ B. Product shade, developer strength, appointment date, and planned haircut.
☐ C. Target shade, processing duration, client satisfaction, and next appointment date.
☐ D. Exact formula, application pattern, processing, and observed color result.
Show answer and explanation
Response:D
Final answer:Exact formula, application pattern, processing, and observed color result.
Preserve the actual formula and process, along with the observed result, so the next consultation can compare what was applied with how the hair responded rather than relying on a target shade or product name alone.
Question 51
For a suitable soft-wax hair-removal service, which direction is used when removing the strip while the skin is held taut?
☐ A. Straight upward away from the skin.
☐ B. Opposite the direction of hair growth.
☐ C. In the direction of hair growth.
☐ D. Sideways across the direction of growth.
Show answer and explanation
Response:B
Final answer:Opposite the direction of hair growth.
Hold the skin taut and remove the soft-wax strip against hair growth with a controlled pull close to the skin, avoiding an upward lift that adds unnecessary traction.
Question 52
An uncoated wooden manicure stick is labelled single-use. After one client, what is its appropriate disposition?
☐ A. Store it with clean tools until it looks dry.
☐ B. Keep it for another client after wiping it.
☐ C. Soak it and treat it as a reusable metal tool.
☐ D. Discard it in the appropriate waste container.
Show answer and explanation
Response:D
Final answer:Discard it in the appropriate waste container.
Discard the single-use stick. Its porous surface and designated single-use status mean that wiping or soaking it does not prepare it for use on another client.
Question 53
During a hydroxide relaxer retouch, why is the formula confined to the indicated new growth while previously relaxed hair is protected?
☐ A. To make previously relaxed ends process faster than new growth.
☐ B. To avoid unnecessary chemical overlap on processed lengths.
☐ C. To replace the system's required neutralizing steps.
☐ D. To increase the degree of relaxation on all older lengths.
Show answer and explanation
Response:B
Final answer:To avoid unnecessary chemical overlap on processed lengths.
Treat the intended new growth. Keep the retouch boundary controlled and protect the previously relaxed lengths so those processed areas avoid repeated chemical exposure that can cause damage.
Question 54
A client with an elongated face asks for a style that makes the face appear shorter. Which design choice best supports that specific goal?
☐ A. Add width at the sides while limiting excessive crown height.
☐ B. Add maximum crown height and keep the sides very flat.
☐ C. Emphasize a long, narrow vertical silhouette.
☐ D. Keep both the crown and sides close to the head.
Show answer and explanation
Response:A
Final answer:Add width at the sides while limiting excessive crown height.
Add side width and limit excessive crown height to support this client's requested shorter appearance, because a tall crown with very flat sides would emphasize an elongated silhouette.
Question 55
A client with highly porous curls already uses rinse-out conditioner but reports dryness between washes. Which additional category best addresses that home-care need?
☐ A. A rinse-out conditioner used during washing with no between-wash product.
☐ B. A suitable leave-in conditioner for moisture care between washes.
☐ C. A clarifying shampoo used between regular washes to address the dryness.
☐ D. A holding spray selected to keep the curls in place between washes.
Show answer and explanation
Response:B
Final answer:A suitable leave-in conditioner for moisture care between washes.
Consider leave-in conditioning. Porous hair can lose moisture between washes, so a suitable leave-in product addresses that need more directly than extra clarifying or a spray selected for hold.
Question 56
A client requests a vigorous scalp massage, but the cosmetologist observes abrasions and irritation. What should happen?
☐ A. Use lighter pressure while massaging over the visible abrasions.
☐ B. Switch to a shorter massage with a cooling lotion on the irritated scalp.
☐ C. Defer the massage and address the scalp condition appropriately.
☐ D. Replace manual massage with a brushing treatment over the irritated area.
Show answer and explanation
Response:C
Final answer:Defer the massage and address the scalp condition appropriately.
Defer the massage. A lighter or shorter technique still subjects an irritated, abraded scalp to the requested manipulation, so the condition needs attention before an appropriate later service.
Question 57
When preparing a woven highlight, what does weaving with the tail of the comb create?
☐ A. All hairs in the subsection without selection.
☐ B. A scalp-to-ends coating of the entire head.
☐ C. Selected small strands separated from the rest of the subsection.
☐ D. One unbroken solid slice of the whole subsection.
Show answer and explanation
Response:C
Final answer:Selected small strands separated from the rest of the subsection.
Weaving selects small strands. With the comb tail, the colorist separates selected hairs within a subsection for isolated highlighting, while a solid slice creates an unbroken section with a different placement pattern.
Question 58
Before adhering a nail tip, how should its width fit the natural nail?
☐ A. Match its free-edge length first and use that size despite a narrower base.
☐ B. Fit the widest tip in the set so it overlaps the lateral skin slightly.
☐ C. Fit from one lateral wall to the other without pressing into the skin.
☐ D. Choose a smaller tip so adhesive fills the spaces at both lateral edges.
Show answer and explanation
Response:C
Final answer:Fit from one lateral wall to the other without pressing into the skin.
Fit the tip to the lateral walls without skin pressure because adhesive is not a substitute for correct width, and the selected free-edge length does not establish a suitable base fit.
Question 59
A cosmetologist stops a service after a minor finger cut, cleans the injury, applies antiseptic, and secures an adhesive bandage. Before handling the client again, what additional protection is appropriate?
☐ A. Add another absorbent dressing over the bandage and resume the service.
☐ B. Wash the hands again and resume with the adhesive bandage as the only covering.
☐ C. Place a clean towel between the bandaged finger and client while continuing the service.
☐ D. Cover the protected injury with a glove or suitable finger guard.
Show answer and explanation
Response:D
Final answer:Cover the protected injury with a glove or suitable finger guard.
Add the protective barrier. A glove or suitable finger guard covers the secured dressing during resumed work, whereas extra absorbent material, another handwash, or a towel does not provide that worn protective covering.
Question 60
A client says a hair dye caused no reaction six months ago. How should the cosmetologist handle the manufacturer's required skin-sensitivity test for today's service?
☐ A. Perform it as directed despite the previous tolerance.
☐ B. Replace it with a hair-strand result test.
☐ C. Perform it only if the formula changes color family.
☐ D. Omit it because one earlier use was tolerated.
Show answer and explanation
Response:A
Final answer:Perform it as directed despite the previous tolerance.
Sensitivity can develop after previous uneventful uses. Follow the current product's testing directions for each use, including today's service, even though the client previously tolerated the dye.
Question 61
During a haircut, a used comb is set beside disinfected combs in a closed storage container. What practice would prevent this contamination?
☐ A. Keep used tools in a separate designated container.
☐ B. Separate the combs only at the end of the day.
☐ C. Store all combs together to reduce handling.
☐ D. Put a clean towel over the mixed combs.
Show answer and explanation
Response:A
Final answer:Keep used tools in a separate designated container.
Separate used and clean tools. Keep used implements in their designated container throughout the service, protecting the reprocessed tools from contact with a comb that has just been used.
Question 62
A disinfectant's label calls for 2 fluid ounces of concentrate per gallon of water. How much concentrate is needed for half a gallon of water?
☐ A. 1 fluid ounce.
☐ B. 4 fluid ounces.
☐ C. 2 fluid ounces.
☐ D. 8 fluid ounces.
Show answer and explanation
Response:A
Final answer:1 fluid ounce.
Half the water quantity requires half the concentrate to preserve the labelled dilution. Half of 2 fluid ounces is 1 fluid ounce.
Question 63
A product-specific amino-acid smoothing service is described as gradually washing out. How does this differ from a permanent relaxer's effect on treated hair?
☐ A. Both maintain the change on treated lengths and require new growth to replace it.
☐ B. Both gradually lose their effect on treated lengths as shampoo removes the treatment.
☐ C. Its effect is renewed only on new growth, while the relaxer's effect is renewed along the treated lengths.
☐ D. Its smoothing effect fades, while permanently relaxed lengths retain their chemical change.
Show answer and explanation
Response:D
Final answer:Its smoothing effect fades, while permanently relaxed lengths retain their chemical change.
Temporary smoothing fades with washing. The specified amino-acid service gradually loses its effect, while permanently relaxed lengths retain their chemical alteration as new hair grows from the follicle.
Question 64
Which statement about exposure is accurate when a smoothing product lists methylene glycol and is heated during use?
☐ A. Closing the bottle before heat styling confines the relevant formaldehyde exposure to dispensing.
☐ B. Ventilation during application is the main control, and the heating stage needs only burn precautions.
☐ C. Heating can release formaldehyde gas that creates an inhalation hazard for workers and clients.
☐ D. An N95 particulate respirator filters the formaldehyde gas released during heat styling.
Show answer and explanation
Response:C
Final answer:Heating can release formaldehyde gas that creates an inhalation hazard for workers and clients.
Heating can release formaldehyde. Review the safety data sheet and ventilation for that stage because closing the bottle or using an N95 particle filter does not control formaldehyde gas released during heat styling.
Question 65
A gel-polish system specifies a compatible lamp and curing cycle. Which practice best supports proper curing?
☐ A. Use a lamp of the same wattage without confirming compatibility with the gel.
☐ B. Use the specified compatible lamp and complete the prescribed curing cycle.
☐ C. Use the compatible lamp for a shorter cycle once the coating looks glossy.
☐ D. Use a longer cycle in an unverified lamp as a substitute for compatibility.
Show answer and explanation
Response:B
Final answer:Use the specified compatible lamp and complete the prescribed curing cycle.
Follow the system's curing conditions. Equal wattage, extra time in an unverified lamp, or a glossy surface does not establish that the gel has received its specified compatible lamp and cycle.
Question 66
A wig is labelled non-heat-resistant synthetic. Which care method is appropriate?
☐ A. Rub the shampoo through the fibers in alternating directions to develop a full lather.
☐ B. Twist the washed lengths inside a towel to remove water before placing it on a stand.
☐ C. Work a fine-tooth comb from the roots through the full length before loosening the end tangles.
☐ D. Wash as directed and allow it to air-dry without hot styling tools.
Show answer and explanation
Response:D
Final answer:Wash as directed and allow it to air-dry without hot styling tools.
Handle the fibers gently. The approved synthetic-care method uses suitable washing, gentle towel patting, wide-tooth detangling, and natural air-drying, with rubbing or twisting avoided during care of the piece.
Question 67
The elbow mainly bends and straightens in the manner of which joint type?
☐ A. Ball-and-socket.
☐ B. Immovable fibrous.
☐ C. Pivot.
☐ D. Hinge.
Show answer and explanation
Response:D
Final answer:Hinge.
A hinge joint chiefly permits bending and straightening. This differs from the broader movement of a ball-and-socket joint and the rotation associated with a pivot joint.
Question 68
During a cut, back sections are directed forward to a guide near the face. What length effect does this overdirection tend to create?
☐ A. More retained length only at the front.
☐ B. Less retained length toward the back.
☐ C. More retained length toward the back.
☐ D. Equal length throughout the back without checking the guide.
Show answer and explanation
Response:C
Final answer:More retained length toward the back.
Directing back sections forward makes them travel farther to the fixed front guide and tends to retain length toward the back, so guide placement changes the haircut's shape.
Question 69
Which structural protein is a principal component of both hair and nails?
☐ A. Elastin.
☐ B. Collagen.
☐ C. Hemoglobin.
☐ D. Keratin.
Show answer and explanation
Response:D
Final answer:Keratin.
Keratin provides structure in hair and nails. Hemoglobin carries oxygen in blood, while collagen and elastin have important roles in connective tissues.
Question 70
A virgin lightening product directs the stylist to apply first to the midlengths and later to the scalp area. Which application follows those directions?
☐ A. Treat the scalp area first and then continue onto the midlengths.
☐ B. Treat the midlengths first, then the scalp area at the directed stage.
☐ C. Treat the midlengths and scalp area together at the first application.
☐ D. Treat the ends first and then finish the whole scalp-to-ends application together.
Show answer and explanation
Response:B
Final answer:Treat the midlengths first, then the scalp area at the directed stage.
Treat midlengths before the scalp area. This product's stated later scalp application should not be replaced by scalp-first or simultaneous application, since those zones can process differently.
Question 71
A nail technician hunches forward to reach a client's unsupported hand. Which adjustment best reduces this strain?
☐ A. Support and raise the hand to a comfortable working height.
☐ B. Add lumbar support while leaving the client's hand at the same low position.
☐ C. Change to a lighter file while keeping the same forward reach.
☐ D. Raise the technician's chair while leaving the hand unsupported on the low table.
Show answer and explanation
Response:A
Final answer:Support and raise the hand to a comfortable working height.
Bring the hand into a supported working position so the technician can reduce the reach and forward bend, rather than changing the file or chair while leaving the work too low.
Question 72
During a consultation, the cosmetologist evaluates how readily the hair absorbs moisture and chemical products. Which characteristic is being assessed?
☐ A. Natural part location.
☐ B. Density.
☐ C. Porosity.
☐ D. Length.
Show answer and explanation
Response:C
Final answer:Porosity.
Porosity describes the hair's ability to absorb moisture and products. Density concerns the number of hairs in an area, so it answers a different consultation question.
Question 73
A heat-friendly synthetic wig's approved care guide directs the stylist to clip a newly formed curl until it is completely cool. Why follow this step?
☐ A. Cooling lets the stylist raise the permitted temperature on the next section.
☐ B. The fiber needs to cool in the intended curl shape.
☐ C. Cooling removes the need to consider whether the synthetic fiber is heat-friendly.
☐ D. Cooling is completed by brushing the curl straight immediately after heating.
Show answer and explanation
Response:B
Final answer:The fiber needs to cool in the intended curl shape.
Cool the fiber in shape. Clipping the formed curl until cool helps set that shape, while the wig's specified heat limits still govern any later heat styling.
Question 74
During a basic daytime makeup application, which product is ordinarily used to set the foundation and control surface shine?
☐ A. Face powder.
☐ B. Cream blush.
☐ C. Skin cleanser.
☐ D. Foundation primer.
Show answer and explanation
Response:A
Final answer:Face powder.
Face powder sets foundation and reduces surface shine. Choose its type and amount for the desired daytime finish and the client's skin.
Question 75
Two suitable permanent-wave services use the same prescribed formula, but different rod sizes and wrapping techniques. What can these mechanical differences affect?
☐ A. The resulting curl size and pattern.
☐ B. The labelled processing limit for that formula.
☐ C. The chemical ingredients listed on the bottle.
☐ D. The product's reducing-agent category.
Show answer and explanation
Response:A
Final answer:The resulting curl size and pattern.
Rod size and wrapping technique help determine curl size and pattern, so two services using the same suitable chemical formula can still produce different shapes through their mechanical arrangement.
Question 76
Which check most directly verifies that warmed soft wax is safe in temperature before skin application?
☐ A. That a small test amount feels warm without hurting or burning.
☐ B. That the wax flows smoothly from the spatula.
☐ C. That the warmer dial matches the setting used at the previous appointment.
☐ D. That the wax has softened enough to spread.
Show answer and explanation
Response:A
Final answer:That a small test amount feels warm without hurting or burning.
Test a small amount by the appropriate method before application because spreadability and a familiar warmer setting do not establish that the wax contacting skin will be comfortably warm rather than too hot.
Question 77
During which hair-growth stage is the follicle actively producing a growing hair?
☐ A. Telogen.
☐ B. Catagen.
☐ C. Exogen.
☐ D. Anagen.
Show answer and explanation
Response:D
Final answer:Anagen.
Anagen is the active growth stage. Catagen is a transition, while telogen is a resting stage, so active production points to anagen.
Question 78
A client can spend only a few minutes styling each morning. Which consultation question best helps choose a workable haircut?
☐ A. Which hair length does the client find most attractive in a reference picture?
☐ B. How does the client usually wear and maintain the hair at home?
☐ C. Which finishing tool would the client be willing to purchase?
☐ D. Which salon styling product does the client prefer for its feel?
Show answer and explanation
Response:B
Final answer:How does the client usually wear and maintain the hair at home?
Ask about the home routine. It shows how the proposed cut can fit the client's available morning time, whereas a preferred photograph, tool purchase, or product feel does not establish the daily maintenance required.
Question 79
Which approach best preserves a natural curl pattern while removing tangles?
☐ A. Use a fine-tooth tool on the entire section before separating smaller sections.
☐ B. Work gently in sections with a suitable wide-tooth tool.
☐ C. Comb from the roots through the full length before addressing knots at the ends.
☐ D. Brush the full section dry until the curl pattern is stretched out.
Show answer and explanation
Response:B
Final answer:Work gently in sections with a suitable wide-tooth tool.
Detangle in manageable sections. A suitable wide-tooth tool allows gentle work through tangles without forcing a fine-tooth tool through them or brushing out the curl pattern.
Question 80
Damage to which structure can affect the production of new nail-plate cells?
☐ A. Hyponychium.
☐ B. Free edge.
☐ C. Lateral groove.
☐ D. Nail matrix.
Show answer and explanation
Response:D
Final answer:Nail matrix.
The matrix produces the cells that form the nail plate. The free edge is the older plate extending beyond the fingertip, so injury there has a different role.
Question 81
Before using a heated iron on a hair section, why does the cosmetologist test the iron's temperature by the approved method?
☐ A. To substitute a standard tool setting for assessment of the hair.
☐ B. To determine how many times the same section should be reheated.
☐ C. To establish one setting suitable for every hair type in the appointment book.
☐ D. To check that the heat is appropriate before contacting the hair.
Show answer and explanation
Response:D
Final answer:To check that the heat is appropriate before contacting the hair.
Check the heat before contact. The suitable setting depends on the hair and tool, so a temperature test supports safe use without replacing hair assessment or establishing a universal setting.
Question 82
What is the main purpose of testing a proposed color formula on a small section of the client's hair before the full service?
☐ A. Confirm that the client will not have a skin reaction to the formula.
☐ B. Determine the finished result from the color chart without testing hair response.
☐ C. Set a processing duration that can be used for all future clients.
☐ D. Evaluate the color result and the hair's response to the proposed process.
Show answer and explanation
Response:D
Final answer:Evaluate the color result and the hair's response to the proposed process.
Test the proposed process on hair. A strand test reveals its color result and the hair's response, while skin sensitivity and a universal processing duration are different questions.
Question 83
A nail-product safety data sheet gives specific waste-disposal instructions. What should the technician do with unused chemical?
☐ A. Follow the product's disposal directions and applicable local requirements.
☐ B. Add it to every leftover product in a common bottle.
☐ C. Leave an open waste container beside the workstation.
☐ D. Pour it into the shampoo sink as a routine disposal method.
Show answer and explanation
Response:A
Final answer:Follow the product's disposal directions and applicable local requirements.
Follow the product's waste instructions. Handle unused chemical according to its safety information and applicable local requirements, using the specified disposal route and keeping incompatible chemical wastes separated.
Question 84
A client with tight natural curls requests a small length reduction. What helps the stylist avoid removing more visible length than intended?
☐ A. Assume wet stretched length equals the final dry length.
☐ B. Pull every curl to its fullest stretch before deciding the finished length.
☐ C. Account for shrinkage and check the shape in its dry curl pattern.
☐ D. Use the wet length alone and skip the dry check.
Show answer and explanation
Response:C
Final answer:Account for shrinkage and check the shape in its dry curl pattern.
Account for the length change as wet curls return to their natural dry pattern, checking the finished shape to avoid cutting beyond the small reduction the client requested.
Question 85
Which of these measured pH values is alkaline?
☐ A. 5.0.
☐ B. 3.0.
☐ C. 9.0.
☐ D. 7.0.
Show answer and explanation
Response:C
Final answer:9.0.
An alkaline value is above pH 7, which makes 9.0 the only alkaline measurement among the four listed choices.
Question 86
Which action is assisted by contraction of the gastrocnemius in the calf?
☐ A. Pointing the foot downward at the ankle.
☐ B. Closing the jaw.
☐ C. Lifting the front of the foot toward the shin.
☐ D. Straightening the fingers.
Show answer and explanation
Response:A
Final answer:Pointing the foot downward at the ankle.
The gastrocnemius assists plantar flexion. Its contraction helps point the foot downward at the ankle, connecting this calf muscle to a movement encountered during a foot service.
Question 87
A storage cabinet is mistakenly described as a sterilizer. What must a process accomplish to qualify as sterilization?
☐ A. Eliminate all forms of microbial life, including bacterial spores.
☐ B. Reduce many pathogens while leaving bacterial spores.
☐ C. Remove visible residue from a tool.
☐ D. Keep previously cleaned tools dry and covered.
Show answer and explanation
Response:A
Final answer:Eliminate all forms of microbial life, including bacterial spores.
Sterilization eliminates all forms of microbial life including bacterial spores, while cleaning, disinfection, and protected storage have separate purposes and holding tools in a cabinet does not establish sterilization.
Question 88
During an ordinary shampoo massage on a healthy scalp, which contact is appropriate?
☐ A. Firm pressure over any visible abrasions.
☐ B. Scraping with the fingernails.
☐ C. Gentle pressure with the pads of the fingers.
☐ D. Repeated pulling at the roots while lathering.
Show answer and explanation
Response:C
Final answer:Gentle pressure with the pads of the fingers.
Finger pads provide controlled massage without scratching the scalp. Fingernails and pointed tools can create abrasions during an otherwise routine shampoo.
Question 89
A small area of nail enhancement has lifted. Which preparation is appropriate before a planned maintenance service on an otherwise healthy nail?
☐ A. Refill the new-growth space first and assess the lifted edge after curing.
☐ B. Gently remove the lifted product by the approved technique and reassess the area.
☐ C. Clean the top surface, then seal the separated edge beneath fresh product.
☐ D. Shorten the free edge and retain the lifted material if it remains attached elsewhere.
Show answer and explanation
Response:B
Final answer:Gently remove the lifted product by the approved technique and reassess the area.
Remove the lifted material first. Controlled preparation and reassessment expose the area before maintenance, whereas a shorter free edge or surface cleaning does not correct separation beneath the product.
Question 90
What should guide glove-material selection when handling a nail chemical?
☐ A. The glove material used successfully for a different chemical at the workstation.
☐ B. The glove's thickness and snug fit, without chemical-resistance information.
☐ C. The product's safety information and the glove's chemical compatibility.
☐ D. The material named for biological protection, without checking solvent resistance.
Show answer and explanation
Response:C
Final answer:The product's safety information and the glove's chemical compatibility.
Check chemical compatibility. A glove chosen for fit, another chemical, or a biological barrier does not establish resistance to the specific product being handled.
Question 91
A colorist describes a shade as level 7 with a cool tone. What does the level number describe?
☐ A. The number of minutes to process the formula.
☐ B. The coolness or warmth of the hue.
☐ C. The shade's degree of lightness or darkness.
☐ D. The diameter of the client's hair strands.
Show answer and explanation
Response:C
Final answer:The shade's degree of lightness or darkness.
Level measures lightness or darkness. A cool tone describes color character, a separate characteristic from the shade's numbered level, which determines neither processing time nor hair-strand thickness.
Question 92
A stylist needs controlled detail work in small cutting sections. Which shear choice best suits that purpose?
☐ A. A long blade intended for covering wide sections quickly.
☐ B. A shorter precision blade that the stylist can control comfortably.
☐ C. Texturizing shears intended mainly to remove bulk.
☐ D. A clipper attachment intended for a uniform short length.
Show answer and explanation
Response:B
Final answer:A shorter precision blade that the stylist can control comfortably.
A shorter precision blade can provide controlled access in small sections. Select shears that suit the technique and that the stylist can hold comfortably throughout the detail work.
Question 93
After the prescribed rinsing and preparation in a thio straightening system, what is the purpose of its oxidizing neutralizer?
☐ A. Serve as the first reducing lotion.
☐ B. Act as a substitute hydroxide neutralizing shampoo.
☐ C. Create the curl shape before the hair is positioned.
☐ D. Help reform disulfide bonds in the new shape.
Show answer and explanation
Response:D
Final answer:Help reform disulfide bonds in the new shape.
Oxidation helps reform disulfide bonds. After the reducing stage changes these bonds, the prescribed thio neutralizer helps reform them in the intended shape, following that system's rinsing and preparation directions.
Question 94
Before directing shampoo water onto a client's scalp, what should the cosmetologist check?
☐ A. That the mixing-control position matches the previous client's setting.
☐ B. That the water feels suitable at the beginning of setup, before it has run through the nozzle.
☐ C. That the running water's temperature is comfortable and safe before scalp contact.
☐ D. That water pressure is suitable, using pressure as a substitute for a temperature check.
Show answer and explanation
Response:C
Final answer:That the running water's temperature is comfortable and safe before scalp contact.
Check the running water. A familiar control position or pressure setting does not verify its actual temperature at the nozzle, and changes during rinsing still need attention.
Question 95
Ringworm of the scalp is caused by which type of organism?
☐ A. A virus.
☐ B. A fungus.
☐ C. A bacterium.
☐ D. A head louse.
Show answer and explanation
Response:B
Final answer:A fungus.
Despite its name, ringworm is a fungal infection. It can spread through infected people, animals, or contaminated objects, so suspected infection calls for appropriate referral and infection-control precautions.
Question 96
An enhancement has grown out, moving its apex away from the intended stress area. What is the purpose of rebalancing?
☐ A. Fill the new-growth gap while preserving the old apex position.
☐ B. Add an even layer over the whole enhancement to replace lost thickness.
☐ C. Shorten the free edge and leave the grown-out structure otherwise unchanged.
☐ D. Restore structural proportions and apex placement for the current nail.
Show answer and explanation
Response:D
Final answer:Restore structural proportions and apex placement for the current nail.
Rebalance the current structure. Filling the gap, adding uniform thickness, or shortening alone can leave the grown-out apex poorly placed for the nail's present length.
Question 97
In which skin layer are hair follicles, oil and sweat glands, blood vessels, and many nerve endings located?
☐ A. Stratum corneum.
☐ B. Epidermis.
☐ C. Dermis.
☐ D. Subcutaneous fat layer.
Show answer and explanation
Response:C
Final answer:Dermis.
The dermis beneath the epidermis contains follicles, glands, blood vessels, and many nerve endings, which helps explain why a deeper injury can involve both bleeding and altered sensation.
Question 98
At a facial-wax consultation, a client reports taking isotretinoin two months ago. What is the appropriate response to the requested waxing service?
☐ A. Apply a protective oil and perform the waxing.
☐ B. Wait another day, then proceed without further assessment.
☐ C. Defer waxing because of the skin-injury risk.
☐ D. Use a smaller strip as the only precaution.
Show answer and explanation
Response:C
Final answer:Defer waxing because of the skin-injury risk.
Defer the waxing service. Recent isotretinoin use creates a skin-injury risk, so direct the client to appropriate medical advice before considering a later service on the affected area.
Question 99
Permanent oxidative hair color develops within which main layer of the hair shaft?
☐ A. Cuticle.
☐ B. Hair bulb.
☐ C. Medulla.
☐ D. Cortex.
Show answer and explanation
Response:D
Final answer:Cortex.
Oxidative color develops in the cortex. This substantial layer lies beneath the protective cuticle, so the permanent coloring process works within the shaft after the product reaches the cortex.
Question 100
During a skin consultation, a client points out a mole that has recently changed size and color. What is the cosmetologist's appropriate next step?
☐ A. Apply stronger exfoliation and check it at the next visit.
☐ B. Diagnose the lesion from its color alone.
☐ C. Recommend medical evaluation rather than attempting to treat the lesion.
☐ D. Conceal it with makeup and continue without discussing referral.
Show answer and explanation
Response:C
Final answer:Recommend medical evaluation rather than attempting to treat the lesion.
A changing mole needs medical evaluation. A cosmetologist can recognize a reason for referral without diagnosing the lesion or trying to remove it during a cosmetic service.
Question 101
A used metal tweezer has visible skin residue on it. What should the cosmetologist do before placing it in the appropriate disinfectant?
☐ A. Clean away the residue with soap and water.
☐ B. Wipe it with a dry towel only.
☐ C. Rinse it briefly without removing the residue.
☐ D. Use disinfectant instead of the cleaning step.
Show answer and explanation
Response:A
Final answer:Clean away the residue with soap and water.
Organic residue can interfere with disinfection. Wash the tweezer first, then use the appropriate disinfectant for its labelled concentration and contact time.
Question 102
A rinse-out conditioner calls for even distribution, a specified conditioning period, and rinsing. The client's lengths tangle easily. Which action follows those directions?
☐ A. Apply at the roots and use the rinse water to carry it through the tangled lengths.
☐ B. Distribute gently through the intended areas, then rinse as directed.
☐ C. Apply at the ends and leave this rinse-out product in place during styling.
☐ D. Apply evenly and rinse before completing the product's directed conditioning period.
Show answer and explanation
Response:B
Final answer:Distribute gently through the intended areas, then rinse as directed.
Distribute and rinse as directed. Applying only at the roots does not ensure the intended lengths receive conditioner, and a rinse-out product should not be treated as leave-in or rinsed before its instructed use is complete.
Question 103
A client wants a one-length perimeter with maximum weight at the bottom. Which cutting approach best supports that result?
☐ A. Cut the perimeter in natural fall with little or no elevation.
☐ B. Use a uniform high-elevation layer throughout.
☐ C. Overdirect every section to the crown.
☐ D. Elevate every section above 90 degrees.
Show answer and explanation
Response:A
Final answer:Cut the perimeter in natural fall with little or no elevation.
Zero elevation preserves perimeter weight. Cutting in natural fall maintains the one-length bottom line, while raising the hair to a high elevation would remove weight and introduce layering.
Question 104
A hydroxide system uses a neutralizing shampoo with an indicator that remains pink when relaxer residue is present. What does pink lather call for?
☐ A. Move to the finishing conditioner while the indicator remains pink.
☐ B. Continue prescribed cleansing and rinsing until the required endpoint.
☐ C. Switch to the oxidizing neutralizer from a thio system.
☐ D. Dilute the shampoo to make the remaining indicator color less visible.
Show answer and explanation
Response:B
Final answer:Continue prescribed cleansing and rinsing until the required endpoint.
Pink still signals residue. Complete this system's prescribed cleansing endpoint instead of hiding the color through dilution or replacing the hydroxide cleansing step with thio oxidation.
Question 105
A client has a fresh abrasion on the lower leg and requests a water-based pedicure. What should the cosmetologist do?
☐ A. Cover the abrasion with a cosmetic barrier cream before immersion.
☐ B. Keep the broken skin out of footspa water and defer the affected service.
☐ C. Shorten the immersion and use freshly changed water for the abrasion.
☐ D. Avoid massaging the abrasion but complete the water immersion.
Show answer and explanation
Response:B
Final answer:Keep the broken skin out of footspa water and defer the affected service.
Keep broken skin out of the footspa. A shorter soak, fresh water, or avoiding massage does not remove the entry point created by the abrasion.
Question 106
A stylist wants high root volume from a wet roller set. Which base placement generally provides the greatest lift?
☐ A. On-base.
☐ B. Half-off-base.
☐ C. Flat against the nape without root elevation.
☐ D. Off-base.
Show answer and explanation
Response:A
Final answer:On-base.
An on-base roller rests within its own base and supports high root lift. Half-off-base placement gives moderate volume, while off-base placement gives less lift.
Question 107
Why should enhancement maintenance include assessment of the client's natural nail and the existing product, rather than a fixed fill regardless of condition?
☐ A. Growth, lifting, and structural balance can change what the service requires.
☐ B. The new-growth gap establishes the structural balance of the existing enhancement.
☐ C. The free-edge length indicates whether product has separated from the natural plate.
☐ D. The previous formula records the natural nail's current condition.
Show answer and explanation
Response:A
Final answer:Growth, lifting, and structural balance can change what the service requires.
Reassess the present nail and product because growth, lifting, and changes in balance affect the maintenance needed, with the gap size, free-edge length, or previous formula alone providing an incomplete service plan.
Question 108
What is a hair follicle?
☐ A. The outermost layer of an exposed hair shaft.
☐ B. The free end of a hair above the scalp.
☐ C. The medulla at the center of a hair shaft.
☐ D. The skin structure from which a hair grows.
Show answer and explanation
Response:D
Final answer:The skin structure from which a hair grows.
Hair grows from a follicle. This opening in the skin is distinct from the exposed shaft and the cuticle covering that shaft.
Question 109
A client returns for a permanent-color retouch and the previously colored lengths still match the target shade. Where is the retouch formula primarily applied?
☐ A. Over the matched lengths first, then the new growth.
☐ B. Primarily to the new growth according to the product directions.
☐ C. To new growth and matched lengths together for the full retouch processing period.
☐ D. To the matched ends first, with the new growth treated only during the final rinse.
Show answer and explanation
Response:B
Final answer:Primarily to the new growth according to the product directions.
