Question 1: According to Texas barbering regulations, what is the minimum
concentration of isopropyl alcohol required for disinfecting non-porous
implements?
A. 50%
B. 60%
C. 70%
D. 90%
CORRECT ANSWER: C. 70%
Rationale: The Texas Department of Licensing and Regulation (TDLR) requires that non-
porous implements be disinfected using an EPA-registered hospital-grade disinfectant
or 70% isopropyl alcohol. This concentration is scientifically proven to effectively kill
most pathogens while maintaining adequate contact time for proper disinfection. Lower
concentrations may not achieve adequate microbial kill, while higher concentrations
evaporate too quickly to ensure proper disinfection contact time.
Question 2: Which of the following bacteria is most commonly associated with
folliculitis barbae in barbering practice?
A. Streptococcus pyogenes
B. Staphylococcus aureus
C. Escherichia coli
D. Pseudomonas aeruginosa
CORRECT ANSWER: B. Staphylococcus aureus
Rationale: Staphylococcus aureus is the primary bacterial pathogen responsible for
folliculitis barbae, an inflammation of hair follicles commonly occurring in the beard
area after shaving. This gram-positive bacterium colonizes the skin and nasal passages
and can enter hair follicles through micro-abrasions caused by shaving. Proper
sanitation of implements and skin preparation are critical preventive measures
mandated by Texas barbering standards.
Question 3: In Texas, how many hours of approved barbering education are required
to qualify for a Class A Barber license?
A. 750 hours
B. 900 hours
C. 1,000 hours
D. 1,500 hours
CORRECT ANSWER: C. 1,000 hours
,Rationale: The Texas Occupations Code Chapter 1603 and TDLR rules specify that
applicants for a Class A Barber license must complete 1,000 hours of instruction at a
TDLR-approved barbering school. This comprehensive curriculum ensures candidates
acquire proficiency in all required barbering services, sanitation protocols, and
regulatory knowledge necessary for safe, competent practice in Texas.
Question 4: When performing a wet shave, what is the primary purpose of applying
a hot towel to the client's face before lathering?
A. To soften the beard hair and open pores
B. To disinfect the facial skin surface
C. To remove excess sebum from the skin
D. To numb the skin for pain reduction
CORRECT ANSWER: A. To soften the beard hair and open pores
Rationale: Applying a hot towel prior to lathering serves to hydrate and soften the beard
hair shaft, making it more pliable and easier to cut cleanly. The heat also promotes
vasodilation, which opens pores and relaxes facial muscles, resulting in a closer, more
comfortable shave with reduced risk of nicks, irritation, or ingrown hairs.
Question 5: Which disinfection method is REQUIRED for metal implements that
have come into contact with blood or bodily fluids in a Texas barbershop?
A. Immersion in 70% isopropyl alcohol for 10 minutes
B. Ultraviolet light exposure for 15 minutes
C. EPA-registered hospital disinfectant with tuberculocidal claim
D. Soap and water scrubbing followed by air drying
CORRECT ANSWER: C. EPA-registered hospital disinfectant with tuberculocidal
claim
Rationale: Texas Administrative Code §83.106 mandates that implements
contaminated with blood or bodily fluids must be cleaned and then immersed in an
EPA-registered hospital disinfectant that is tuberculocidal (effective against
Mycobacterium tuberculosis). This standard ensures destruction of bloodborne
pathogens including HIV, HBV, and HCV, protecting both clients and practitioners from
cross-contamination.
Question 6: What is the correct sequence for cleaning and disinfecting barbering
implements according to TDLR standards?
A. Disinfect, rinse, clean, dry, store
B. Clean, rinse, disinfect, rinse, dry, store
C. Rinse, disinfect, clean, dry, store
D. Clean, disinfect, rinse, store immediately
CORRECT ANSWER: B. Clean, rinse, disinfect, rinse, dry, store
,Rationale: Proper implement processing follows a specific sequence: first, clean with
soap and water to remove visible debris; rinse to remove cleaning residue; immerse in
EPA-registered disinfectant for required contact time; rinse with clean water to remove
chemical residue; air-dry completely; and store in a clean, covered container. This
protocol ensures effective pathogen elimination while preventing chemical irritation to
clients.
Question 7: Which layer of the skin contains the hair follicles, sebaceous glands,
and sweat glands relevant to barbering services?
A. Epidermis
B. Dermis
C. Hypodermis
D. Stratum corneum
CORRECT ANSWER: B. Dermis
Rationale: The dermis is the thick, inner layer of skin that houses hair follicles,
sebaceous (oil) glands, sudoriferous (sweat) glands, blood vessels, and nerve endings.
Understanding dermal anatomy is essential for barbers to perform services safely, avoid
injury to these structures, and recognize conditions that may contraindicate certain
treatments.
Question 8: In Texas, within how many days must a licensed barber notify TDLR of a
change of business address?
A. 10 days
B. 15 days
C. 30 days
D. 60 days
CORRECT ANSWER: C. 30 days
Rationale: Texas Administrative Code §83.91 requires licensees to notify the Texas
Department of Licensing and Regulation in writing of any change of business or mailing
address within 30 days of the change. This regulation ensures accurate licensing
records, facilitates official communications, and supports regulatory oversight of
barbering establishments statewide.
Question 9: What is the primary function of a neck duster during a barbering
service?
A. To apply aftershave lotion evenly
B. To remove loose hair clippings from the client's neck and face
C. To exfoliate dead skin cells before shaving
D. To disinfect the skin surface post-service
CORRECT ANSWER: B. To remove loose hair clippings from the client's neck and
face
, Rationale: A neck duster, typically made of soft bristles or synthetic fibers, is used to
gently brush away loose hair clippings from the client's neck, face, and shoulders after
cutting or shaving. This enhances client comfort, maintains a professional appearance,
and prevents irritation from stray hairs. The duster itself must be cleaned and
disinfected between clients per TDLR sanitation rules.
Question 10: Which of the following is a CONTRAINDICATION for performing a
chemical relaxer service?
A. Client has fine, straight hair
B. Scalp has open abrasions or lesions
C. Client prefers a natural curl pattern
D. Hair was last cut three weeks ago
CORRECT ANSWER: B. Scalp has open abrasions or lesions
Rationale: Chemical relaxers contain strong alkaline agents (e.g., sodium hydroxide,
guanidine hydroxide) that can cause severe chemical burns if applied to compromised
skin. Texas barbering standards require practitioners to perform a thorough scalp
examination prior to any chemical service and defer treatment if abrasions, lesions,
inflammation, or infections are present to prevent injury and liability.
Question 11: What is the minimum contact time required when using an EPA-
registered quaternary ammonium compound disinfectant for non-porous
implements in Texas?
A. 5 minutes
B. 10 minutes
C. 15 minutes
D. As specified on the product label
CORRECT ANSWER: D. As specified on the product label
Rationale: TDLR regulations require that disinfectants be used strictly according to the
manufacturer's label instructions, including dilution ratios and contact time.
Quaternary ammonium compounds vary in formulation, and only the label-specified
contact time ensures validated efficacy against target pathogens. Using disinfectants
contrary to label directions violates both state regulations and federal EPA guidelines.
Question 12: Which angle of elevation is typically used when cutting a blunt or one-
length haircut?
A. 0 degrees (no elevation)
B. 45 degrees
C. 90 degrees
D. 180 degrees
CORRECT ANSWER: A. 0 degrees (no elevation)
