ACTUAL QUESTIONS
Domain 1: Hair Care and Styling
Question 1. Which layer of the hair shaft provides most of the hair's strength,
elasticity, and natural pigment?
A. Cuticle
B. Hair bulb
C. Medulla
D. Cortex
Correct Answer: D
Rationale: The cortex forms most of the hair shaft and contains keratin structures,
side bonds, and melanin. Chemical texture and permanent color services create
their major changes within this layer.
Question 2. What generally occurs when an alkaline product is applied to the
hair?
A. The cuticle swells and lifts, allowing greater penetration into the cortex.
B. The cuticle contracts tightly and blocks all product entry.
C. The medulla becomes the only layer affected.
D. The hair becomes permanently neutral without chemical change.
Correct Answer: A
,Rationale: Alkaline products raise pH, soften and swell the hair, and lift cuticle
scales. This increased penetration supports chemical action but also raises the risk
of structural damage when strength or timing is poorly controlled.
Question 3. A strand absorbs moisture almost immediately but loses it rapidly
and feels rough. How should its porosity be classified?
A. Low porosity
B. High elasticity
C. Normal density
D. High porosity
Correct Answer: D
Rationale: Highly porous hair has a raised or damaged cuticle, so liquids enter
and leave quickly. Product strength, application sequence, and processing time
should be adjusted to avoid uneven or excessive chemical action.
Question 4. During a wet-hair assessment, a strand stretches slightly and
returns to its original length without breaking. What does this indicate?
A. Severe loss of porosity
B. Normal elasticity
C. No cortical strength
D. A contagious scalp disorder
Correct Answer: B
Rationale: Healthy elasticity allows wet hair to stretch moderately and return
because cortical protein and side bonds retain resilience. Hair that snaps quickly
or remains stretched may not tolerate a strong chemical service safely.
Question 5. Which phase of hair growth is characterized by active growth and
lasts for 2 to 6 years?
A. Catagen phase
B. Telogen phase
C. Anagen phase
D. Resting phase
Correct Answer: C
Rationale: The anagen phase is the active growth phase of hair, lasting for 2 to 6
years. The catagen phase is a transition phase, and the telogen phase is the resting
phase.
Question 6. What is the primary function of the hair cuticle?
A. To provide color to the hair
,B. To protect the inner structure of the hair
C. To transport nutrients to the hair
D. To regulate hair growth
Correct Answer: B
Rationale: The cuticle is the outermost layer of the hair, composed of overlapping
scales that protect the cortex and medulla from damage.
Question 7. A client has a coarse hair texture and wants a smooth blowout.
Which styling tool is most appropriate?
A. A fine-tooth comb
B. A boar-bristle brush
C. A wide-tooth comb
D. A pick
Correct Answer: B
Rationale: Boar-bristle brushes are ideal for coarse hair as they distribute natural
oils and help smooth the cuticle during blow-drying.
Question 8. Which chemical service requires the use of a neutralizer to reform
disulfide bonds?
A. Hair coloring
B. Permanent waving
C. Shampooing
D. Hair cutting
Correct Answer: B
Rationale: Permanent waving uses a reducing agent to break disulfide bonds and a
neutralizer (oxidizing agent) to reform them in the new shape.
Question 9. What is the pH range of hair and skin?
A. 1.0 - 3.0
B. 4.5 - 5.5
C. 7.0 - 8.5
D. 9.0 - 10.5
Correct Answer: B
Rationale: Healthy hair and skin have a pH of approximately 4.5 to 5.5, which is
slightly acidic. This helps keep the cuticle closed and protects the hair.
Question 10. Which type of hair color requires a patch test 24 to 48 hours
before application?
A. Temporary color
, B. Semi-permanent color
C. Permanent oxidative color
D. Hair gloss
Correct Answer: C
Rationale: Permanent oxidative hair colors contain PPD (paraphenylenediamine)
or similar chemicals that can cause severe allergic reactions. A patch test is
mandatory according to manufacturer instructions and board regulations.
Question 11. What is the purpose of a developer (hydrogen peroxide) in hair
coloring?
A. To add moisture to the hair
B. To lighten the hair and develop the color
C. To condition the hair
D. To neutralize the hair
Correct Answer: B
Rationale: Developer (hydrogen peroxide) lifts the cuticle, lightens the natural
pigment (melanin), and oxidizes the color molecules to develop the final color.
Question 12. Which type of haircut involves cutting the hair at a 90-degree
angle from the head?
A. Blunt cut
B. Graduated cut
C. Uniform layer cut
D. Long layer cut
Correct Answer: C
Rationale: A uniform layer cut (or 90-degree cut) involves holding the hair at a
90-degree angle from the scalp, creating layers of equal length.
Question 13. What is the term for the process of removing excess bulk from
the hair without shortening the overall length?
A. Clipper cutting
B. Texturizing
C. Blunt cutting
D. Slicing
Correct Answer: B
Rationale: Texturizing (or thinning) removes excess bulk and weight from the hair,
allowing for better movement and shaping without changing the overall length.
