SOLUTION.
Question 1
Under which of the following circumstances should a barber definitely NOT proceed with a
chemical service?
A) The client has curly hair.
B) The client is wearing a hearing aid.
C) There are signs of scalp irritation or abrasions.
D) The client has previously used permanent color.
E) The client has vellus hair on the neck.
Correct Answer: C) there are signs of irritation or abrassions
Rationale: Safety is the primary concern during chemical services. If the scalp has open
sores, scratches, or inflammation, the chemicals in perms, relaxers, or hair color can cause
severe burns, chemical reactions, or infections. Always perform a thorough scalp analysis
before applying any chemical.
Question 2
When performing the "shear-over-comb" technique, how should the tools be positioned in
relation to each other?
A) The shear should be held at a 45-degree angle to the comb.
B) The shear and comb are parallel to each other.
C) The comb should be held vertically while shears are horizontal.
D) The moving blade of the shear should touch the comb's teeth.
E) The comb should be held away from the head at all times.
Correct Answer: B) shear and comb are parallel to each other, with the still blade aligned
where the teeth meet the comb's spine
Rationale: For precision and control, the barber must keep the comb and shear parallel.
The still blade of the shear rests on the spine of the comb to provide stability, allowing the
moving blade to cut the hair evenly as the comb moves up the head.

Question 3
Which roller placement is used when the barber desires a curl with maximum volume, sitting
directly on its base?
A) Off-base
B) Half-off base
C) Over-directed
D) On-base
E) Indentation
Correct Answer: D) on-base
Rationale: On-base placement (also called full-base) involves wrapping the hair at an angle
higher than 90 degrees from the center of the base. The roller then sits directly between the
partings of the base, which provides the most lift and volume at the scalp.
Question 4
In the structure of the hair, which bonds are specifically broken and reformed by the chemicals
used in permanent waving and relaxing?
A) Hydrogen bonds
B) Salt bonds
C) Disulfide bonds
D) Peptide bonds
E) Keratin chains
Correct Answer: C) disulfied bonds are broken by chemicals
Rationale: While hydrogen and salt bonds are physical side bonds broken by water or heat,
disulfide bonds are strong chemical side bonds. They can only be broken by chemical
solutions (reducing agents) and must be reformed by a neutralizer to lock the hair into its
new shape.
Question 5
How is a thio-based relaxer properly neutralized during a chemical service?
A) By rinsing with cold water for 10 minutes.
B) Through the application of a chemical neutralizing solution.
, 3
C) By using a neutralizing shampoo immediately.
D) By applying a deep conditioner.
E) By letting the hair air dry for 20 minutes.
Correct Answer: B) a chemical neutralizing solution
Rationale: Thio relaxers require a specific chemical neutralizer (usually containing
hydrogen peroxide) to rebuild the disulfide bonds that were broken during the softening
process. This is distinct from hydroxide relaxers, which are neutralized through physical
rinsing and acidic shampoo.
Question 6
What is the standard procedure for neutralizing a hydroxide relaxer?
A) Applying a leave-in conditioner.
B) Applying a thio-neutralizer.
C) Through rinsing and shampooing with a neutralizing shampoo.
D) Using a high-heat blow dryer.
E) Brushing the hair vigorously to restore the bonds.
Correct Answer: C) through rinsing and shampooing with a neutralizing shampoo
Rationale: Hydroxide relaxers are not compatible with thio neutralizers. To stop the
chemical action of a hydroxide relaxer, the hair must be thoroughly rinsed to remove the
high-pH chemical and then washed with an acidic neutralizing shampoo to restore the
hair's natural pH.
Question 7
According to Texas Barber regulations, if a barber needs a duplicate license or needs to make a
revision to their existing license, what is the required fee?
A) $10
B) $15
C) $25
D) $50
E) No fee is required for duplicates.
, 4
Correct Answer: C) $25
Rationale: The Texas Department of Licensing and Regulation (TDLR) sets specific
administrative fees for license maintenance. A $25 fee is mandated for processing a
duplicate license or updating information on a current license.
Question 8
What is the technical term for a chronic inflammatory condition of the beard area that resembles
folliculitis, commonly known as "razor bumps"?
A) Folliculitis barbae
B) Tinea sycosis
C) Pseudofolliculitis
D) Seborrhea
E) Alopecia areata
Correct Answer: C) pseudofollicultis
Rationale: Pseudofolliculitis barbae is caused by ingrown hairs, often resulting from
shaving too closely or against the grain. The hair curves back into the skin, causing
inflammation and bumps that look like an infection but are actually a mechanical
irritation.
Question 9
How long can head lice (pediculosis capitis) typically survive once they are separated from a
human host?
A) 12 hours
B) 24 hours
) 48 hours
D) 1 week
E) 1 month
Correct Answer: C) up to 48 hours
Rationale: Head lice are parasites that require the warmth and blood of a human scalp to
survive. Once removed from the body, they generally die within 48 hours due to lack of
food and environmental stress.
