  1. Q21When performing a basic haircut, the term 'elevation' refers to:

    • AThe direction in which the hair is combed before cutting
    • BThe length guide established at the beginning of the haircut
    • CThe number of sections the hair is divided into
    • DThe angle at which the hair section is held away from the head before cutting
    Show answer

    ✓ Correct answer: D. The angle at which the hair section is held away from the head before cutting

    Elevation (also called projection or lifting) is the angle at which the hair is held away from the scalp during cutting; higher elevation creates more layering and graduation, while zero elevation produces a blunt, one-length effect.

  2. Q22A cosmetologist notices a client has an itchy scalp with oval, yellowish-white nits attached to the hair shafts. The correct professional response is to:

    • APolitely decline the service and refer the client to a physician
    • BApply a medicated shampoo and proceed with the service
    • CDrape the client with an extra towel and complete the haircut quickly
    • DDisinfect the tools and continue with a scalp massage
    Show answer

    ✓ Correct answer: A. Politely decline the service and refer the client to a physician

    Pediculosis capitis (head lice) is a contagious infestation; the cosmetologist must not perform the service on an infested client, must sanitize and disinfect all exposed surfaces, and should refer the client to a physician for treatment.

  3. Q23Which of the following correctly describes the function of the hair's medulla?

    • AIt is the innermost layer of the hair shaft, present in coarse or thick hair, with an unclear but non-structural role
    • BIt provides the hair's tensile strength and elasticity
    • CIt produces the sebum that coats and protects the hair shaft
    • DIt controls the rate of hair growth from the follicle base
    Show answer

    ✓ Correct answer: A. It is the innermost layer of the hair shaft, present in coarse or thick hair, with an unclear but non-structural role

    The medulla is the innermost, central layer of the hair shaft; it is present primarily in coarse or terminal hair and absent in fine hair, and does not contribute significantly to hair strength or elasticity.

  4. Q24During the catagen phase of the hair growth cycle, which of the following occurs?

    • AThe hair is shed and a new anagen phase begins immediately
    • BRapid mitotic cell division in the hair matrix produces new hair cells
    • CThe follicle is completely inactive and no cell activity takes place
    • DThe follicle transitions and shrinks as cell production slows and the hair detaches from the papilla
    Show answer

    ✓ Correct answer: D. The follicle transitions and shrinks as cell production slows and the hair detaches from the papilla

    Catagen is a brief transitional phase lasting 1–2 weeks, during which cell division in the hair matrix slows and then stops, the follicle shrinks, and the hair detaches from the dermal papilla to form a club hair.

  5. Q25A client with tinea capitis should be treated with:

    • AHydrogen peroxide applied to the affected area before the haircut
    • BNo cosmetology service; the client must be referred to a physician for antifungal treatment
    • CA conditioning shampoo and scalp massage to stimulate circulation
    • DAn antibacterial shampoo recommended by the cosmetologist
    Show answer

    ✓ Correct answer: B. No cosmetology service; the client must be referred to a physician for antifungal treatment

    Tinea capitis is a contagious fungal infection of the scalp; cosmetologists are prohibited from treating any contagious scalp disorder and must refer affected clients to a licensed physician.

  6. Q26When performing a blunt, one-length haircut, the cosmetologist uses a stationary guideline and cuts all subsequent sections to match it. This guideline technique is most accurately described as a:

    • ATraveling guideline
    • BPerimeter or stationary guideline
    • CPivoting guideline
    • DInterior guideline
    Show answer

    ✓ Correct answer: B. Perimeter or stationary guideline

    A stationary (or perimeter) guideline remains in a fixed position and is not moved as subsequent sections are cut; it is the foundation of the one-length blunt cut and ensures uniform length throughout.

  7. Q27A cosmetologist is about to shampoo a client who has visible open lesions and abrasions on the scalp. Which infection-control principle most directly requires the cosmetologist to decline the shampoo service?

    • AOpen lesions represent a contraindication because they create a portal of entry for pathogens, elevating transmission risk for both client and cosmetologist
    • BThe cosmetologist must first sterilize all implements in an autoclave before touching broken skin
    • CEPA-registered disinfectants must be applied to the scalp before water contact
    • DStandard precautions require treating all clients as potentially infectious regardless of visible lesions
    Show answer

    ✓ Correct answer: A. Open lesions represent a contraindication because they create a portal of entry for pathogens, elevating transmission risk for both client and cosmetologist

    Open lesions and abrasions on the scalp are a contraindication to shampooing because broken skin provides a direct portal of entry for pathogens; performing the service could harm the client and expose the cosmetologist to bloodborne or other pathogens.

  8. Q28Alopecia areata is best characterized as:

    • AProgressive, diffuse hair loss caused by prolonged, excessive tension on the hair shaft from tight hairstyles
    • BDiffuse hair shedding triggered by severe physical or emotional stress occurring 2–3 months after the stressor
    • CA patchy, non-scarring hair loss condition believed to be an autoimmune response where the body attacks its own hair follicles
    • DGradual hair thinning caused by the conversion of terminal follicles to vellus follicles under the influence of DHT
    Show answer

    ✓ Correct answer: C. A patchy, non-scarring hair loss condition believed to be an autoimmune response where the body attacks its own hair follicles

    Alopecia areata is classified as an autoimmune condition in which the immune system mistakenly attacks hair follicles, producing well-defined, smooth, patchy areas of non-scarring hair loss that can occur anywhere on the scalp or body.

  9. Q29Permanent waving solution (waving lotion) works by breaking which type of bond in the hair's cortex?

    • AHydrogen bonds
    • BPeptide bonds
    • CDisulfide bonds
    • DSalt bonds
    Show answer

    ✓ Correct answer: C. Disulfide bonds

    Permanent waving lotion is an alkaline reducing agent that breaks the strong disulfide (cystine) bonds in the cortex, allowing the hair to be reshaped around a rod.

  10. Q30After the waving lotion has processed, the neutralizer is applied during a permanent wave service. What is the primary function of the neutralizer?

    • ATo swell the cuticle so color can penetrate
    • BTo remove the alkaline waving lotion from the scalp
    • CTo lower the hair's porosity before rinsing
    • DTo re-form disulfide bonds in the hair's new shape
    Show answer

    ✓ Correct answer: D. To re-form disulfide bonds in the hair's new shape

    The neutralizer is an oxidizing agent that re-forms (rebuilds) the disulfide bonds in their new configuration around the rod, locking in the curl pattern.
