,1. A cosmetologist is performing a chemical relaxer service on a client with
previously lightened hair. The relaxer is applied to the regrowth only. After
processing, the hair appears overly straight and shows signs of breakage at the
demarcation line. Which factor most likely contributed to this outcome?
A. The relaxer was left on too long.
B. The relaxer was not neutralized properly.
C. The relaxer was applied to porous hair without a protective base.
D. The relaxer was too high in strength for the hair type.
Answer: C. The relaxer was applied to porous hair without a protective base.
Lightened hair is highly porous and can absorb relaxer quickly, leading to
overprocessing and breakage at the demarcation line. Applying a protective base to
previously lightened hair is critical to prevent this. While other options could cause
issues, the specific scenario points to porosity and lack of protection.
2. A client presents with a history of allergic reactions to hair dye. A patch test is
administered 48 hours prior to a color service. The test site shows slight redness and
itching. What is the appropriate course of action?
A. Proceed with the color service using a lower developer volume.
B. Proceed with the color service but apply a barrier cream to the scalp.
C. Cancel the color service and recommend an alternative like vegetable-based dyes.
D. Perform a second patch test with a different brand of color.
Answer: C. Cancel the color service and recommend an alternative like
vegetable-based dyes.
A positive patch test indicates a sensitivity or allergy to the dye. It is unsafe to proceed
with any product containing similar ingredients. Vegetable-based dyes are less likely to
cause reactions and are a safer alternative. Ignoring a positive test could lead to severe
allergic reactions.

,3. Which of the following best describes the mechanism of action of alpha hydroxy
acids (AHAs) in chemical exfoliation?
A. They break down intercellular lipids in the stratum corneum.
B. They dissolve desmosomes between corneocytes, promoting shedding.
C. They increase collagen synthesis by stimulating fibroblasts.
D. They neutralize free radicals to prevent oxidative damage.
Answer: B. They dissolve desmosomes between corneocytes, promoting shedding.
AHAs work by chelating calcium ions, which disrupts desmosomes that hold
corneocytes together, leading to exfoliation. Option A describes the action of solvents or
detergents, not AHAs. Option C is a secondary effect of some AHAs but not the
primary mechanism. Option D describes antioxidants.
4. A cosmetologist is mixing a permanent hair color with a 20-volume developer. The
mixture is applied to the client's hair and processed for 30 minutes. The result is a
lighter shade than expected. What is the most likely reason?
A. The developer was actually 30-volume due to mislabeling.
B. The hair was pre-lightened before the color service.
C. The color was left on for too long.
D. The color formula contained too much pigment.
Answer: A. The developer was actually 30-volume due to mislabeling.
A 20-volume developer lifts 1-2 levels, while 30-volume lifts 2-3 levels. If the developer
was mislabeled, the higher volume would cause more lift, resulting in a lighter shade.
Pre-lightened hair would require a lower volume to avoid over-lifting. Processing time
and pigment concentration would not typically cause a lighter shade without other
factors.

, 5. In the context of sanitation, which of the following is true regarding the use of an
autoclave in a salon setting?
A. It is used to disinfect non-porous tools like combs and brushes.
B. It sterilizes by using high-pressure steam at a specific temperature and time.
C. It is an alternative to chemical disinfectants for all tools.
D. It requires tools to be submerged in a chemical solution before use.
Answer: B. It sterilizes by using high-pressure steam at a specific temperature and
time.
An autoclave uses steam under pressure to achieve sterilization, killing all
microorganisms including spores. It is not typically used for non-porous tools like
combs, which can be sanitized with chemical disinfectants. It is not an alternative for all
tools, as some may be damaged by heat. Prior submersion is not required.
6. A client with oily skin requests a facial treatment. Which of the following
ingredients would be most beneficial to include in the treatment?
A. Squalane and ceramides
B. Salicylic acid and niacinamide
C. Hyaluronic acid and glycerin
D. Retinol and vitamin C
Answer: B. Salicylic acid and niacinamide
Salicylic acid is a beta-hydroxy acid that penetrates oil-filled pores to exfoliate and
reduce oiliness. Niacinamide helps regulate sebum production. Squalane and ceramides
are more suited for dry or compromised skin. Hyaluronic acid and glycerin are
humectants for hydration. Retinol and vitamin C are anti-aging but not specifically for
oil control.
