,1. A client presents with a history of allergic reactions to hair dyes containing
paraphenylenediamine (PPD). The salon uses a new oxidative hair color that
contains a derivative of PPD but claims to be 'hypoallergenic.' Which chemical
principle explains why cross-reactivity is still possible?
A. PPD derivatives have a similar quinone structure that can still bind to immune receptors
B. Hypoallergenic products contain lower concentrations of allergen, but cumulative
exposure triggers reaction
C. Oxidative coupling alters the allergen so it is no longer recognized by IgE antibodies
D. The pH of the new color is higher, which denatures the allergen and prevents sensitization
Answer: A. PPD derivatives have a similar quinone structure that can still bind to
immune receptors
PPD and its derivatives share a quinone structure that is the actual immunogenic
moiety. Even if the parent compound is modified, the quinone formed during oxidation
can still cross-link with skin proteins and trigger an allergic response. Hypoallergenic
claims are not regulated and do not guarantee absence of cross-reactivity. Options B, C,
and D are incorrect because concentration, oxidative coupling, and pH do not eliminate
the fundamental allergenic determinant.
2. During a scalp massage, a cosmetologist inadvertently applies excessive pressure
over the temporal region. The client experiences immediate dizziness and blurred
vision. Which anatomical structure most likely has been compromised?
A. Superficial temporal artery, reducing blood flow to the cerebral cortex
B. Trigeminal nerve (V2 branch), causing referred pain and autonomic symptoms
C. Temporomandibular joint (TMJ) capsule, leading to vertigo
D. Temporal lobe via external compression, affecting visual processing
Answer: A. Superficial temporal artery, reducing blood flow to the cerebral cortex
The superficial temporal artery runs over the temporal bone and supplies blood to the
scalp and parts of the brain. Excessive pressure can temporarily reduce blood flow,
leading to dizziness and visual disturbances due to cerebral hypoperfusion. The
trigeminal nerve (V2) is not primarily responsible for dizziness or vision. TMJ
compression causes pain, not dizziness. External compression of the temporal lobe is
unlikely through the skull.

,3. A nail technician observes that a client's natural nails have a yellow-green
discoloration, a foul odor, and slight separation from the nail bed. The client reports
no pain. Which condition is most likely, and what is the appropriate professional
action?
A. Pseudomonas aeruginosa infection; remove artificial enhancements and refer to a
physician
B. Fungal onychomycosis; apply topical antifungal and continue services with gloves
C. Allergic contact dermatitis; change to hypoallergenic products and monitor
D. Nail psoriasis; apply corticosteroid cream and schedule follow-up
Answer: A. Pseudomonas aeruginosa infection; remove artificial enhancements
and refer to a physician
Yellow-green discoloration and foul odor are classic signs of Pseudomonas bacterial
infection, often under artificial nails. The bacteria thrive in moist environments
between the natural nail and enhancement. Pain is usually absent. The correct action is
to remove the enhancement, clean the nail, and refer to a physician for possible
antibiotic treatment. Fungal infections typically cause yellow-brown discoloration and
thickening, not green. Allergic dermatitis presents with redness and itching, not odor.
Psoriasis causes pitting and onycholysis without the characteristic green color.
4. A stylist applies a permanent wave solution to virgin hair, processes for the
recommended time, and then neutralizes. After rinsing, the hair appears frizzy and
has lost its curl pattern. Which factor most likely caused this outcome?
A. Overlapping of the waving solution on previously permed ends
B. Insufficient neutralization leaving disulfide bonds in a reduced state
C. Excessive heat from the dryer during processing
D. Using a rod size too small for the hair length
Answer: B. Insufficient neutralization leaving disulfide bonds in a reduced state
If neutralization is incomplete, the disulfide bonds remain in the reduced (broken) state,
unable to reform in the new curl pattern. This causes loss of curl and frizziness.
Overlapping would cause damage but usually results in breakage, not just frizz. Heat
during processing can accelerate the reaction but typically does not prevent curl
formation if neutralization is adequate. Rod size affects curl tightness, not the chemical
bonding itself; too small a rod would create tighter curls, not frizz.

, 5. A cosmetology student is asked to identify the pH of a solution that has a hydrogen
ion concentration of 1 × 10^-3 mol/L. Which pH value is correct, and what does this
imply about the solution's effect on hair?
A. pH 3; acidic solution that will tighten the hair cuticle
B. pH 7; neutral solution that has no effect on hair
C. pH 11; alkaline solution that will swell the hair cuticle
D. pH 3; alkaline solution that will cause hair damage
Answer: A. pH 3; acidic solution that will tighten the hair cuticle
pH is the negative logarithm of hydrogen ion concentration: pH = -log[H+]. For [H+] =
1e-3, pH = 3, which is acidic. Acidic solutions (pH < 7) cause the hair cuticle to contract
and lie flat, increasing shine and smoothness. Option B is incorrect because pH 7
corresponds to 1e-7 M. Option C is wrong because pH 11 is alkaline (1e-11 M). Option
D incorrectly labels pH 3 as alkaline.
6. A salon manager wants to implement a chemical inventory system compliant with
OSHA Hazard Communication Standard. Which of the following is the minimum
requirement for each product?
A. Safety Data Sheet (SDS) readily accessible to all employees
B. A written hazard communication program updated annually
C. Product labels with pictograms, signal words, and hazard statements
D. All of the above
Answer: D. All of the above
OSHA's Hazard Communication Standard (HCS) requires employers to have a written
program, maintain SDSs for each hazardous chemical, ensure proper labeling
(including pictograms, signal words, hazard statements, and precautionary statements),
and provide training. All three elements (A, B, C) are mandatory. Therefore, the
correct answer is D.
