,1. A cosmetologist is performing a chemical relaxer service on hair that has been
previously colored with a metallic salt dye. Which of the following is the most critical
risk to consider?
A. The relaxer may cause the hair to become overly porous, leading to uneven curl reduction.
B. The metallic salts can react with the relaxer, causing hair breakage and scalp burns.
C. The color will lift unevenly, resulting in patchy tones.
D. The relaxer will neutralize the metallic salts, rendering the color ineffective.
Answer: B. The metallic salts can react with the relaxer, causing hair breakage and
scalp burns.
Metallic salts in some hair dyes can cause a violent exothermic reaction with chemical
relaxers, leading to hair damage and scalp injury. This is a critical safety concern
beyond porosity or color issues.
2. During a pedicure, a client presents with thickened, discolored toenails and a foul
odor. The cosmetologist suspects a fungal infection. According to Colorado state
regulations, which action is most appropriate?
A. Proceed with the pedicure after applying a topical antifungal agent.
B. Refuse service and recommend the client see a medical professional.
C. Perform the pedicure using separate, disposable tools to prevent cross-contamination.
D. Soak the feet in a vinegar solution before continuing the service.
Answer: B. Refuse service and recommend the client see a medical professional.
Colorado cosmetology law prohibits performing services on clients with visible signs of
infection. The cosmetologist must refuse service and refer the client to a healthcare
provider.
3. Which of the following best describes the function of the arrector pili muscle in the
context of hair removal?
A. It secretes sebum to lubricate the hair follicle during extraction.
B. It contracts to cause goosebumps, which can affect the angle of hair growth.
C. It anchors the hair shaft to the dermal papilla.
D. It dilates blood vessels to nourish the hair bulb.
Answer: B. It contracts to cause goosebumps, which can affect the angle of hair
growth.
The arrector pili is a smooth muscle that contracts in response to cold or fear, causing
piloerection (goosebumps). This can alter the hair's angle, impacting hair removal
techniques.

,4. A salon uses a 5.25% sodium hypochlorite solution for disinfecting implements.
Which of the following statements about this practice is correct?
A. The solution is effective against HIV and hepatitis B with a 10-minute immersion.
B. Sodium hypochlorite at this concentration is a sterilant.
C. This solution is safe for use on metal tools without risk of corrosion.
D. The solution must be diluted to 1:10 for use as a disinfectant.
Answer: A. The solution is effective against HIV and hepatitis B with a 10-minute
immersion.
A 5.25% sodium hypochlorite solution (household bleach) is an effective disinfectant
against bloodborne pathogens when used at full strength with proper immersion time.
It is not a sterilant and can corrode metals.
5. A client with fine, limp hair desires a body wave. The cosmetologist selects a perm
solution with a pH of 9.0. Which of the following is the most likely outcome?
A. The wave will be weak and fall out quickly due to insufficient curl activation.
B. The hair may become overly swollen and damaged because the solution is too alkaline.
C. The solution will produce a firm curl that lasts longer than expected.
D. The hair's cuticle will close, preventing the solution from penetrating.
Answer: B. The hair may become overly swollen and damaged because the solution
is too alkaline.
Fine hair has a smaller diameter and is more susceptible to damage from alkaline
solutions. A pH of 9.0 is high enough to cause excessive swelling and potential damage,
especially on fine hair.
6. In the context of color theory, when a yellow base is mixed with a violet base in
equal proportions, the resulting color is:
A. A neutral brown or gray.
B. A vibrant green.
C. A muted orange.
D. A deep purple.
Answer: A. A neutral brown or gray.
Yellow and violet are complementary colors on the color wheel. When mixed, they
neutralize each other, producing a neutral brown or gray.

, 7. A cosmetologist notices that after applying a gel nail polish and curing under a UV
lamp, the polish appears wrinkled and dull. What is the most likely cause?
A. The gel was applied too thickly.
B. The UV lamp was too powerful.
C. The nail plate was not dehydrated properly.
D. The gel was not fully cured due to insufficient exposure time.
Answer: A. The gel was applied too thickly.
Wrinkling of gel polish typically occurs when the product is applied in thick layers. The
outer layer cures and shrinks faster than the inner layer, causing a wrinkled surface.
8. Which of the following is a key difference between a bacitracin allergy and a
neomycin allergy in the context of cosmetic products?
A. Bacitracin allergies are more common than neomycin allergies.
B. Neomycin allergy is often delayed and cross-reacts with other aminoglycosides.
C. Bacitracin causes immediate anaphylaxis, while neomycin causes contact dermatitis.
D. Neomycin is less likely to cause sensitization than bacitracin.
Answer: B. Neomycin allergy is often delayed and cross-reacts with other
aminoglycosides.
Neomycin is a common contact allergen that often presents as delayed hypersensitivity.
It can cross-react with other aminoglycosides. Bacitracin allergy is less frequent but
may cause anaphylaxis.
9. A salon professional is preparing a disinfectant solution using a quaternary
ammonium compound (quat). Which factor most significantly reduces the efficacy of
quats?
A. High temperature of the solution.
B. Presence of organic matter such as hair clippings.
C. Low pH of the water used for dilution.
D. Exposure to UV light.
Answer: B. Presence of organic matter such as hair clippings.
Quaternary ammonium compounds are cationic detergents that are easily inactivated
by organic matter. Hair clippings, blood, or other debris can bind to the quat molecules,
reducing their disinfectant activity.
