A. Immerse the entire clipper in liquid disinfectant.B. Spray or wipe the clipper with an EPA-registered disinfectant per its label.C. Store it in a clean drawer without further treatment.D. Wash the clipper head with soap and water, then skip chemical disinfection.
Answer and explanations Correct answer: B. Spray or wipe the clipper with an EPA-registered disinfectant per its label.
Option A: Immersion is the procedure for many non-electrical tools; the electrical-tool rule calls for an EPA-registered spray or wipe.Option B · Correct answer: Correct. The label must show bactericidal, fungicidal, and virucidal activity; follow its directions for the spray or wipe.Option C: Clean storage follows disinfection; it does not replace the required treatment before use.Option D: Cleaning with soap and water does not replace the specified disinfectant treatment for an electrical tool.2 / 25 Consultation and hair and skin analysis A barber reviewing a skin diagram for a facial-hair consultation points to the layer beneath the epidermis that contains blood vessels, nerve endings, and oil and sweat glands. Which layer is it? Choose one answer
A. The epidermis, the outer visible layer.B. The dermis, beneath the epidermis.C. The hypodermis, the deepest main layer.D. The stratum corneum.
Answer and explanations Correct answer: B. The dermis, beneath the epidermis.
Option A: The epidermis is the outer layer; the named structures are described in the dermis.Option B · Correct answer: Correct. The NIAMS skin lesson places blood vessels, nerve endings, and oil and sweat glands in the dermis.Option C: The hypodermis lies deeper and connects skin to underlying structures; it is not the layer identified here.Option D: The stratum corneum is at the surface, not the dermal layer with these structures.3 / 25 Hairstyling Before a curling service, a barber notices that the electric iron’s cord is frayed. What is the safest next step? Choose one answer
A. Lower the iron temperature and continue.B. Use it only with completely dry hands.C. Remove the iron from use until it is repaired or replaced.D. Keep the cord away from the client and use the iron.
Answer and explanations Correct answer: C. Remove the iron from use until it is repaired or replaced.
Option A: Lower heat does not repair a frayed electrical cord or remove shock risk.Option B: Dry hands reduce one shock risk, but the Board advises repairing or discarding a frayed or defective iron.Option C · Correct answer: Correct. The Board advises checking cords and repairing or discarding defective electric irons.Option D: Moving the cord does not resolve the electrical defect for the worker or client.4 / 25 Haircutting A barber sketches a proposed haircut and marks its length and sectioning. What else should the structural plan record to guide how each section is cut? Choose one answer
A. The lift angle and distribution of the hair.B. The cutting tools and finishing products.C. A reference photo of the finished style.D. The operator’s hand position and cape placement.
Answer and explanations Correct answer: A. The lift angle and distribution of the hair.
Option A · Correct answer: Correct. After length and sectioning are marked, lift angle and hair distribution tell the barber how to control each section in the planned cut.Option B: Tools and finishing products matter, but they do not specify a section’s lift or distribution.Option C: A style photo shows the target look, but not the lift angle or distribution for each section.Option D: Hand position and caping concern execution and protection, not the planned lift/distribution geometry.5 / 25 Haircoloring A client wants softly blended highlights around a side part. What should guide the barber’s foil direction? Choose one answer
A. Match the angles to foil width.B. Match the angles to developer strength.C. Match the angles to natural hair fall.D. Match the angles to the color level.
Answer and explanations Correct answer: C. Match the angles to natural hair fall.
Option A: Foil width affects section size, but it does not show how highlights will fall around the part.Option B: Developer selection is a separate formulation decision, not the visual direction of foil placement.Option C · Correct answer: Correct. Plan foil direction around how the hair falls from the part and the visible result the client wants.Option D: Color level affects the formula and target shade, but not how foils appear when the hair falls.6 / 25 Chemical texture services During a permanent-wave service, a barber wants to reduce hand contact with the waving solution. Which sequence does the California Board safety sheet recommend? Choose one answer
A. Apply solution to loose hair, then cut and wrap it.B. Apply solution, wrap the hair, then complete the cut.C. Complete the cut and wrap, then apply the solution.D. Cut the hair, apply solution, then wrap it.
Answer and explanations Correct answer: C. Complete the cut and wrap, then apply the solution.
Option A: Applying solution before cutting and wrapping increases opportunities for hand contact during those tasks.Option B: The cut and wrap are still being done after chemical application, contrary to the Board precaution.Option C · Correct answer: Correct. The Board advises cutting and rolling the hair before putting on waving solution to limit hand exposure.Option D: Cutting first helps, but wrapping after applying solution still exposes the hands; the Board advises cutting and rolling before solution.7 / 25 Skin care Two clients ask for a facial massage, but their skin elasticity and preferences differ. How should a barber plan the movement and duration? Choose one answer
A. Use the salon’s usual movements, adjusting only pressure.B. Adapt movements and duration to each client.C. Change only the finishing product, not the massage.D. Use a longer duration for both so neither is shortchanged.
Answer and explanations Correct answer: B. Adapt movements and duration to each client.
Option A: Pressure alone does not account for the different movement and duration needs described in the scenario.Option B · Correct answer: Correct. The cited Australian training unit calls for adapting facial-massage movement and length to skin characteristics and client needs, which differ between these two clients.Option C: Product choice alone does not address the movement and duration the unit says to adapt.Option D: More time for both does not tailor movement or duration to each client’s skin and preferences.8 / 25 Shaving A client requests a close neck shave, but the skin in that area is visibly inflamed. What should the barber do? Choose one answer
A. Use a fresh blade and make shorter strokes over the inflamed area.B. Decline to shave the inflamed area and explain why to the client.C. Refuse every service today and require a doctor’s written clearance.D. Apply extra shaving cream and use less pressure over the inflammation.
Answer and explanations Correct answer: B. Decline to shave the inflamed area and explain why to the client.
Option A: A new blade and shorter strokes do not change the prohibition on working over inflamed skin.Option B · Correct answer: Correct. California bars services on an area of skin that is inflamed, broken, infected, or has an eruption.Option C: The rule bars service on the affected area; it does not automatically bar unrelated services or require a doctor’s note for this finding.Option D: Cream and lighter pressure do not remove the contraindication created by the inflamed skin.9 / 25 Safety and infection control A reusable cape is clean, but it would touch the next client’s neck directly. What should the barber add? Choose one answer
A. A sanitary neck strip or clean towel between the cape and neck.B. Disinfectant sprayed on the cape collar instead of a neck barrier.C. A second cape over the first one.D. Nothing, because the cape was laundered.
Answer and explanations Correct answer: A. A sanitary neck strip or clean towel between the cape and neck.
Option A · Correct answer: Correct. The barrier keeps the protective covering from directly contacting the client’s neck.Option B: Disinfecting the cape does not replace the sanitary neck strip or clean towel barrier.Option C: Layering capes still leaves a protective covering directly against the neck.Option D: Laundering the cape is important, but the neck-strip rule still requires a barrier.10 / 25 Consultation and hair and skin analysis A barber assesses very porous hair before color. How is artificial color likely to behave? Choose one answer
A. Weak uptake and faster fading.B. Weak uptake and longer retention.C. Strong uptake and longer retention.D. Strong uptake and faster fading.
Answer and explanations Correct answer: D. Strong uptake and faster fading.
Option A: Very porous hair tends to take up artificial color strongly, so weak uptake is the wrong expectation.Option B: Both predictions reverse the tendency described for very porous hair.Option C: Uptake may be strong, but artificial color can fade more quickly from very porous hair.Option D · Correct answer: Correct. Very porous hair may absorb artificial color intensely and then lose it faster.11 / 25 Hairstyling While brush-drying a client’s hair for a smooth finish, which airflow direction is best? Choose one answer
A. Across the shaft from alternating sides.B. From the ends upward toward the roots.C. From the roots down toward the ends.D. Directly at one point without moving it.
Answer and explanations Correct answer: C. From the roots down toward the ends.
Option A: Alternating cross-shaft airflow does not follow the direction of the cuticle scales.Option B: That direction runs against the usual orientation of the cuticle scales.Option C · Correct answer: Correct. Airflow directed down the shaft follows the hair-cuticle direction for the planned finish.Option D: Holding air at one point does not describe airflow along the cuticle direction.12 / 25 Haircutting A barber is midway through a layered cut. Some uncut sections have dried while earlier sections were cut wet. What adjustment keeps the work consistent with the plan? Choose one answer
A. Continue cutting; match the dry sections at the finish.B. Cut every section dry even if the plan used wet hair.C. Use a fixed lift angle to offset the moisture difference.D. Restore even moisture and follow the planned partings.
Answer and explanations Correct answer: D. Restore even moisture and follow the planned partings.
Option A: Deferring the mismatch leaves the current sections at different moisture levels rather than following the planned wet-cut pattern.Option B: The criterion allows consistently wet or dry hair; it does not require a switch to dry cutting.Option C: A fixed lift angle does not replace moisture and sectioning control.Option D · Correct answer: Correct. In the cited Australian training unit, consistently wet or dry hair and logical partings support the planned layered cut; rewet the dried sections before continuing this wet cut.13 / 25 Haircoloring A client wants highlights that blend softly into the existing hair color. Which foil selection most directly supports that effect? Choose one answer
A. A heavy weave adjusted to the hair texture and density.B. A fine weave adjusted to the hair texture and density.C. A medium weave adjusted to the hair texture and density.D. Thin slices adjusted to the hair texture and density.
Answer and explanations Correct answer: B. A fine weave adjusted to the hair texture and density.
Option A: A heavy weave tends to create more visible contrast than a fine weave.Option B · Correct answer: Correct. Fine weaving generally makes a more blended highlight; the section still must suit this hair.Option C: A medium weave generally gives more noticeable dimension than the softer blend requested.Option D: Slices tend to make more distinct streaks than a fine weave.14 / 25 Chemical texture services While winding a permanent wave, a barber sees bent hair ends caught under one rod. What should be done before applying the waving solution? Choose one answer
A. Rewind with even tension and no hooked ends.B. Leave the wrap; the bent ends will smooth out during processing.C. Tighten the rod band over the bent ends.D. Apply more waving solution only to the bent ends.
Answer and explanations Correct answer: A. Rewind with even tension and no hooked ends.
Option A · Correct answer: Correct. Rewinding corrects the bent ends before solution is applied and restores the even tension specified for this step.Option B: Processing does not correct a poor wrap; bent ends must be rewound before solution is applied.Option C: A tighter band does not correct the winding and may increase marks or breakage.Option D: Extra chemical cannot replace a clean wrap without hooked ends.15 / 25 Skin care During a neck shave, a client asks the barber to slice off a small skin tag with the razor. What is the correct response? Choose one answer
A. Remove it after applying an antiseptic.B. Remove it if the client signs a waiver.C. Shave firmly over it so it comes off.D. Decline; removing skin with a razor is invasive.
Answer and explanations Correct answer: D. Decline; removing skin with a razor is invasive.
Option A: An antiseptic does not change the act; § 991(b)(5) lists removal of skin with a razor-edged tool as invasive.Option B: A signed waiver does not permit a procedure that § 991 prohibits.Option C: Shaving it off is still removal of skin with a razor-edged tool, which § 991 prohibits.Option D · Correct answer: Correct. Article 12 § 991 prohibits invasive procedures, including removal of skin with a razor-edged tool.16 / 25 Shaving A warmed towel feels too hot on the barber’s wrist before a face shave. What should happen before it touches the client? Choose one answer
A. Fold the towel thicker and apply it at once.B. Ask the client to tolerate the heat briefly.C. Cool it and test it again on the wrist.D. Place it over the cape instead of the face.
Answer and explanations Correct answer: C. Cool it and test it again on the wrist.
Option A: Folding it does not establish that the contact temperature is comfortable.Option B: The barber should correct an overly hot towel before placing it on the face.Option C · Correct answer: Correct. The cited shave procedure checks towel comfort on the wrist and retests after an overly hot towel is cooled.Option D: Moving the towel away from the face does not prepare a comfortable face towel for this service.17 / 25 Safety and infection control A barber is preparing the shampoo station for another client. What does California require for the tray and bowl? Choose one answer
A. Rinse loose hair out of the bowl with water, then dry the tray and bowl.B. Clean the shampoo tray and bowl with soap and water or another detergent.C. Spray the bowl with disinfectant without first washing it with detergent.D. Wipe the tray with a clean towel and rinse the bowl with plain water.
Answer and explanations Correct answer: B. Clean the shampoo tray and bowl with soap and water or another detergent.
Option A: Rinsing and drying omit the detergent cleaning required after each shampoo.Option B · Correct answer: Correct. The rule calls for cleaning the shampoo tray and bowl after every shampoo and keeping them sanitary.Option C: Disinfectant spray alone omits the prescribed washing with soap and water or other detergent.Option D: A towel and plain-water rinse do not provide the required detergent cleaning of both surfaces.18 / 25 Consultation and hair and skin analysis A client wants a clean nape outline, but the hair changes direction at a cowlick. What should the barber do while planning the outline? Choose one answer
A. Check the growth pattern and agree on the outline.B. Copy the reference photo without checking the nape.C. Draw a new straight line against the growth pattern.D. Choose the outline only after cutting the nape.
Answer and explanations Correct answer: A. Check the growth pattern and agree on the outline.
Option A · Correct answer: Correct. The growth change can affect how the nape outline looks as it grows back, so assess it with the client first.Option B: A photo does not reveal this client’s nape growth direction.Option C: A forced line ignores the cowlick and may change appearance as the hair grows back.Option D: The growth pattern should inform the plan before the cutting starts.19 / 25 Hairstyling A round brush catches while the barber releases a blow-dried section. What should the barber do before pulling it free? Choose one answer
A. Pull the brush straight out without rotating it.B. Gently reverse the brush rotation to unwind the hair.C. Wrap another turn around the brush first.D. Twist the brush farther in its original direction.
Answer and explanations Correct answer: B. Gently reverse the brush rotation to unwind the hair.
Option A: A straight pull can tighten the trapped hair rather than unwind it.Option B · Correct answer: Correct. The cited blowout instructions release a caught brush by reversing its rotation.Option C: Adding a turn increases the wrap when the immediate need is to release it.Option D: Continuing the original rotation tightens the wrap rather than reversing it.20 / 25 Haircutting While a barber uses unguarded clippers at the nape, the client says the blade feels like it is scraping the skin. What should the barber do before continuing? Choose one answer
A. Use firmer pressure to complete the area with fewer passes.B. Keep the same pressure but move the clippers more slowly.C. Reduce blade pressure and check the client’s comfort.D. Switch to a trimmer and press it firmly against the same area.
Answer and explanations Correct answer: C. Reduce blade pressure and check the client’s comfort.
Option A: More pressure with an unguarded clipper increases the risk of irritation or abrasion.Option B: Slowing the movement does not address the excessive blade pressure indicated by the client.Option C · Correct answer: Correct. Unguarded clippers can irritate or abrade skin under excess pressure; ease the pressure and confirm comfort.Option D: A trimmer used with excessive pressure can also irritate or abrade the skin.21 / 25 Haircoloring A barber is creating a bold foil accent on very dense hair. Which check most directly prevents an unevenly processed slice? Choose one answer
A. Whether the slice is thin enough for product to saturate it.B. Whether the foils follow the planned diagonal placement.C. Whether the spacing between foils gives the planned contrast.D. Whether each foil is folded evenly along its edges.
Answer and explanations Correct answer: A. Whether the slice is thin enough for product to saturate it.
Option A · Correct answer: Correct. A bold slice can still be too thick for full saturation, especially in dense hair.Option B: Placement affects the visible accent, but it does not establish whether product reaches the middle of each slice.Option C: Spacing determines the distribution of highlights, not saturation within one foil.Option D: A neat fold helps contain the section but cannot correct a slice too thick for product to penetrate.22 / 25 Chemical texture services During a chemical straightening service on previously treated hair, a barber is combing the product through with strong tension. What adjustment should the barber make? Choose one answer
A. Keep the tension but work faster to shorten contact time.B. Stop combing and let the product spread on its own.C. Switch to a wide-tooth comb but keep the same tension.D. Comb gently without stretching, using the planned pattern.
Answer and explanations Correct answer: D. Comb gently without stretching, using the planned pattern.
Option A: Working faster does not correct stretching; this step calls for gentle combing without stretch, while timing follows product directions.Option B: The procedure calls for even application in a planned pattern; leaving the product to spread on its own does not do that.Option C: A different comb does not remove the stretch caused by strong tension.Option D · Correct answer: Correct. Easing the combing tension keeps the previously treated hair from being stretched while the product follows the planned application pattern.23 / 25 Skin care A facial client arrives with styling product residue along the forehead and surface oil on the face. What is the purpose of the first pre-cleanse? Choose one answer
A. To leave residue for the skin analysis.B. To remove surface oil and residue.C. To replace every later cleanse.D. To exfoliate the living dermis.
Answer and explanations Correct answer: B. To remove surface oil and residue.
Option A: Residue can obscure the skin; pre-cleansing removes it.Option B · Correct answer: Correct. The cited facial guide assigns this purpose to pre-cleansing.Option C: The guide follows pre-cleanse with a main cleanse.Option D: A pre-cleanse removes surface residue; dermal exfoliation is not its purpose.24 / 25 Shaving A barber removes a used blade from a replaceable-blade razor after a shave. Where should the blade go? Choose one answer
A. In the covered bin for hair clippings.B. In the closed hamper for used towels.C. In the holder for clean razor handles.D. In the container designated for sharps.
Answer and explanations Correct answer: D. In the container designated for sharps.
Option A: A covered hair bin does not contain a sharp blade safely.Option B: The linen hamper is for washable fabric, not a used razor blade.Option C: A used removable blade should not be placed with clean equipment.Option D · Correct answer: Correct. The cited barbering text directs used razor blades to a sharps container after service.25 / 25 Safety and infection control A barber has a new hair-color product and needs to know what chemicals it must be kept away from. Which SDS section should they read? Choose one answer
A. Section 1, identification of the product and supplier.B. Section 4, first-aid measures after exposure.C. Section 7, precautions for handling and storage.D. Section 8, exposure controls and personal protection.
Answer and explanations Correct answer: C. Section 7, precautions for handling and storage.
Option A: Section 1 identifies the product and supplier; it is not the SDS location for storage incompatibilities.Option B: Section 4 addresses first aid if exposure occurs, not routine storage conditions.Option C · Correct answer: Correct. Section 7 covers safe handling and storage conditions, including incompatibilities.Option D: Section 8 concerns exposure controls and protective equipment; it does not replace Section 7 for storage.
