Kansas Barber Licensing Examination
with Practice Questions And Correct
Answers (Verified
1. A barber uses a disinfectant labeled 'tuberculocidal, hospital-grade' on a
blood-contaminated straight razor. After cleaning with soap and water, the razor is
immersed for 5 minutes. According to Kansas Board regulations and CDC guidelines,
what is the most critical error in this process?
A. The razor should not be disinfected; it must be sterilized in an autoclave.
B. The immersion time is insufficient; tuberculocidal disinfectants require a minimum
10-minute contact time.
C. Soap and water cleaning is unnecessary before disinfection for bloodborne pathogens.
D. The disinfectant must be changed daily regardless of contamination level.
Answer: B. The immersion time is insufficient; tuberculocidal disinfectants require a
minimum 10-minute contact time.
Rationale: Most tuberculocidal hospital-grade disinfectants require a minimum 10-minute
contact time for efficacy against bloodborne pathogens; 5 minutes is inadequate.
Autoclaving is not required for razors unless penetrating skin, and cleaning before
disinfection is mandatory. Daily changing is not the critical error here.
2. A client with tightly coiled, highly porous hair requests a relaxer. The barber
performs a patch test and strand test. The strand test shows severe breakage after 5
minutes. Which of the following is the most appropriate professional decision?
A. Proceed with the relaxer but reduce processing time to 3 minutes.
B. Use a milder relaxer and apply a protective base to the scalp.
C. Refuse the relaxer service and recommend a conditioning treatment instead.
D. Proceed with the relaxer after applying a protein filler.
Answer: C. Refuse the relaxer service and recommend a conditioning treatment
instead.
Rationale: Severe breakage during a strand test indicates the hair cannot withstand the
chemical service; proceeding risks further damage. Reducing time or using a milder
relaxer may still cause breakage. A protein filler does not prevent breakage from
incompatible chemicals.

,3. During a shave, a barber notices a client has a raised, inflamed, pus-filled lesion on
the cheek. The barber should:
A. Shave around the lesion and apply a styptic pencil.
B. Discontinue the shave and refer the client to a physician.
C. Drain the lesion with a sterile lancet and continue.
D. Apply a hot towel and proceed with the shave.
Answer: B. Discontinue the shave and refer the client to a physician.
Rationale: A pus-filled lesion may be a sign of infection (e.g., folliculitis, impetigo) and
shaving could spread infection or cause injury. Referring to a physician is required.
Draining or shaving over it is unsafe and outside scope of practice.
4. A barber is mixing a hair color formula. The client's hair is 30% gray and the
desired result is a level 6 neutral brown. The barber uses a level 6 ash color with 20
volume developer. What is the most likely outcome?
A. The hair will appear too warm due to insufficient gray coverage.
B. The hair will appear too cool or green due to the ash tone.
C. The hair will be one level lighter than desired.
D. The hair will have perfect gray coverage and neutral tone.
Answer: B. The hair will appear too cool or green due to the ash tone.
Rationale: Ash tones contain blue/green bases that can create unwanted cool or green
casts, especially on gray hair. A neutral or natural series would be better for gray
coverage. The level and developer are appropriate for deposit only, but the ash tone is the
issue.

, 5. Which of the following statements about the hair growth cycle is correct and
relevant to barbering services?
A. Telogen effluvium is characterized by sudden shedding of hairs in the anagen phase.
B. The majority of scalp hair is in the catagen phase at any given time.
C. The anagen phase determines the maximum length of hair growth.
D. The telogen phase is the active growth phase of hair.
Answer: C. The anagen phase determines the maximum length of hair growth.
Rationale: The anagen phase is the active growth phase, and its duration determines how
long hair can grow. Telogen is the resting phase, and most scalp hair is in anagen. Telogen
effluvium involves shedding of telogen hairs.
6. A barber is performing a haircut using the shear-over-comb technique. Which of
the following best describes the primary advantage of this technique?
A. It creates a blunt cut line with minimal texturizing.
B. It allows for precise blending and gradual tapering of hair lengths.
C. It is the fastest method for removing bulk from thick hair.
D. It requires no comb and uses clippers directly on the scalp.
Answer: B. It allows for precise blending and gradual tapering of hair lengths.
Rationale: Shear-over-comb allows the barber to cut hair at varying lengths by using the
comb as a guide, enabling precise blending and tapering. It is not primarily for blunt cuts
or bulk removal, and it involves shears and comb, not clippers directly.
