,1. A cosmetologist is formulating a corrective color for a client whose hair has been
lightened to a pale yellow (level 9) but presents with uneven porosity due to previous
chemical services. The goal is a neutral, ash blonde (level 8). Which of the following
approaches best achieves the desired result while minimizing damage and ensuring
even color deposition?
A. Apply a permanent color with a green base to neutralize yellow tones, using a 20-volume
developer.
B. Pre-treat the hair with a protein filler, then apply a semi-permanent color with a
blue-violet base.
C. Use a high-lift tint with a violet base and 30-volume developer to simultaneously lighten
and tone.
D. Apply a demi-permanent color with a blue base after a porosity equalizing treatment.
Answer: B. Pre-treat the hair with a protein filler, then apply a semi-permanent
color with a blue-violet base.
The correct answer is B. Uneven porosity requires a filler to ensure even uptake. A
semi-permanent color with blue-violet cancels yellow while minimizing further damage.
Option A: green base is for red tones, not yellow; 20-volume may lift too much. Option
C: high-lift tint with 30-volume over lightened hair risks overprocessing and
unevenness. Option D: demi-permanent may not provide enough gray coverage if
needed, and blue alone may result in greenish tones on yellow.
2. During a scalp examination, a cosmetologist observes multiple small,
erythematous papules with pustules at the follicle openings, accompanied by yellow
crusts. The client reports mild itching but no pain. Which of the following conditions
is most consistent with these findings?
A. Seborrheic dermatitis
B. Tinea capitis
C. Folliculitis decalvans
D. Contact dermatitis
Answer: B. Tinea capitis
The correct answer is B. Tinea capitis, a fungal infection, often presents with
erythematous papules, pustules, and yellow crusts (kerion) with itching. Option A:
seborrheic dermatitis typically has greasy, yellowish scales without pustules. Option C:
folliculitis decalvans is a scarring alopecia with painful pustules and tufted hairs.
Option D: contact dermatitis presents with vesicles and weeping, not pustules at
follicles.

,3. A manufacturer claims a new hair relaxer has a pH of 11.5 and contains guanidine
carbonate. Which of the following statements best evaluates the chemical process
and potential risks of this product?
A. It is a thio-based relaxer that breaks disulfide bonds via reduction; pH 11.5 is safe for all
hair types.
B. It is a hydroxide relaxer that converts to guanidine hydroxide, breaking disulfide bonds
irreversibly; pH 11.5 indicates high alkalinity, increasing risk of hair damage and scalp
burns.
C. It is a combination relaxer that both reduces and oxidizes bonds; pH 11.5 is optimal for
minimizing irritation.
D. It is a low-pH relaxer that uses enzymatic action to break bonds; pH 11.5 is an error in
labeling.
Answer: B. It is a hydroxide relaxer that converts to guanidine hydroxide,
breaking disulfide bonds irreversibly; pH 11.5 indicates high alkalinity, increasing
risk of hair damage and scalp burns.
The correct answer is B. Guanidine carbonate, when mixed with calcium hydroxide,
forms guanidine hydroxide, a strong alkali (pH ~13.5, but 11.5 is still highly alkaline). It
breaks disulfide bonds irreversibly. Option A: thio relaxers use ammonium
thioglycolate, not guanidine. Option C: no combination relaxer works that way. Option
D: enzymatic relaxers are not standard and pH 11.5 is dangerously high for hair.

, 4. A cosmetologist is performing a strand test on a client whose hair was previously
colored with a metallic dye. The test reveals immediate breakage and a rubbery
texture. Which of the following best explains this reaction and the appropriate next
step?
A. The metallic dye contains silver nitrate, which reacts with ammonia in the new color to
form explosive compounds; discontinue service and refer to a physician.
B. The metallic salts in the previous dye react with hydrogen peroxide to generate heat,
causing hair degradation; avoid peroxide-based services and use a color remover without
peroxide.
C. The metallic dye caused protein loss; apply a deep conditioner and proceed with a
semi-permanent color.
D. The metallic dye is incompatible with all color services; cut the hair short and start over.
Answer: B. The metallic salts in the previous dye react with hydrogen peroxide to
generate heat, causing hair degradation; avoid peroxide-based services and use a
color remover without peroxide.
The correct answer is B. Metallic dyes (e.g., lead acetate) react with hydrogen peroxide
exothermically, causing breakage. The appropriate step is to avoid peroxide and use a
color remover designed for metallic salts. Option A: silver nitrate is not typical;
explosive reactions are rare. Option C: conditioning cannot fix the chemical
incompatibility. Option D: cutting may be necessary but is not the immediate next step.
