  1. 1A newly hired cosmetologist is ready to serve paying clients in Kansas but has not yet received an individual license. What must occur before the cosmetologist begins practicing?

    1. A. An individual cosmetologist license
    2. B. A salon or clinic license
    3. C. A cosmetology apprentice license
    4. D. A cosmetology instructor license

    Answer: A

    Explanation: Kansas law states, "no person shall ... engage in practice of cosmetology ... unless the person holds a valid license, issued by the board." The salon's license does not replace the practitioner's own license.

    Reference: Kansas Cosmetology Law Book — K.S.A. 65-1902(a)(1)

  2. 2When must a Kansas practitioner clean the hands or use alcohol-based hand sanitizer in relation to each client service?

    2. B. Only before the first service of the day
    3. C. Only after visible contamination
    4. D. At the end of each workweek

    Answer: A

    Explanation: K.A.R. 28-24-2 says each practitioner shall do so "before and after each consumer service."

  3. 3Where may a Kansas practitioner carry instruments and supplies while working?

    2. B. In an instrument belt worn at the waist
    3. C. In a uniform-pocket organizer
    4. D. Pinned to an apron

    Answer: A

    Explanation: The rule says, "No practitioner shall carry any instrument or supplies in or on a garment or uniform, including an instrument belt and an instrument organizer."

    Reference: Kansas Cosmetology Law Book — K.A.R. 28-24-14(b)

  4. 4What can frequent use of a formaldehyde-containing nail hardener do to nails?

    1. A. Make them brittle and more likely to break or peel
    2. B. Guarantee permanent flexibility
    3. C. Eliminate all allergic reactions
    4. D. Convert the nail plate into living tissue

    Answer: A

    Explanation: FDA says frequent use "may make nails brittle and more likely to break or peel."

    Reference: Nail Care Products | FDA — Formaldehyde in Nail Hardeners and Nail Polishes

  5. 5During a Kansas salon service, the practitioner discovers ringworm on the client. What is the practitioner's first required action?

    1. A. Stop the service safely
    2. B. Inform the consumer why the service stopped
    3. C. Clean and disinfect affected tools and areas
    4. D. Put on single-use protective gloves

    Answer: A

    Explanation: K.A.R. 28-24-3(b) first requires the practitioner to "Stop services immediately in a safe manner."

    Reference: Kansas Cosmetology Law Book — K.A.R. 28-24-3(b)(1)

  6. 6A client has used the same coal-tar hair color before without a reaction. What allergy precaution is still recommended before this application?

    1. A. Perform the directed skin patch test before every use
    2. B. Skip testing because the prior service was uneventful
    3. C. Test only after the color is applied
    4. D. Replace the patch test with a strand-shape check

    Answer: A

    Explanation: FDA notes that sensitivities and formulas can change and says to "do the skin test before every use."

    Reference: Hair Dyes | FDA — Safety Issues—Allergic reactions

  7. 7A manicure client has thin nails with rough free edges. Which filing motion should the cosmetologist use to smooth those edges while limiting further weakening?

    1. A. Repeated back-and-forth strokes across the free edge
    2. B. Alternating leftward and rightward strokes across the free edge
    3. C. Repeated circular strokes on the free edge and nail surface
    4. D. Consistent strokes across the free edge in one direction

    Answer: D

    Explanation: The American Academy of Dermatology advises, "Always pull the file across the nail in the same direction. Filing back and forth can weaken nails." Back-and-forth and alternating strokes reverse direction; circular motion also changes direction and extends onto the nail surface. A consistent single direction is the supported technique.

    Reference: American Academy of Dermatology, Teaching Your Child Healthy Nail Care — Teaching your child healthy nail care, nail filing advice

  8. 8After a Kansas eyebrow waxing service, product remains in a roll-on wax cartridge used on that client. What should the practitioner do with the cartridge?

    1. A. Clean and disinfect it, then reserve it for the same client
    2. B. Close and store it, then use it on a later salon client
    3. C. Discard it in a covered waste receptacle after the service
    4. D. Sterilize it, then return it to the station's clean supply

    Answer: C

    Explanation: K.A.R. 28-24-7(c) states, "Each roll-on wax cartridge shall be considered a single-use item and shall be disposed of in a covered waste receptacle after the service." Remaining product does not change its classification. Cleaning, storing, or sterilizing it for reuse conflicts with this explicit single-use rule.

    Reference: Kansas Cosmetology Law Book — K.A.R. 28-24-7(c), Waxing

  9. 9Which paid service falls within the Kansas statutory practice of cosmetology?

    1. A. Permanently coloring the hair
    2. B. Tattooing pigment into living skin
    3. C. Removing hair with an electric needle
    4. D. Performing a medical skin biopsy

    Answer: A

    Explanation: Kansas defines cosmetology to include "temporarily or permanently coloring ... the hair." Tattooing, electrology, and medical procedures are separately regulated.

    Reference: Kansas Cosmetology Law Book — K.S.A. 65-1901(d)(1)(A)

  10. 10A Kansas client has visible head lice. What must the client provide before the practitioner may perform a service?

    1. A. A physician-signed statement that the condition is not infectious, contagious, or communicable
    2. B. A salon waiver signed by the client
    3. C. A receipt for an over-the-counter product
    4. D. A verbal assurance from another stylist

    Answer: A

    Explanation: The rule bars service until the consumer furnishes "a statement signed by a licensed physician stating that the communicable disease or condition is not in an infectious, contagious, or communicable stage."

    Reference: Kansas Cosmetology Law Book — K.A.R. 28-24-3(a)(1)
