FLORIDA COSMETOLOGY CLINICAL
FINAL EXAM 2027 QUESTIONS AND
ANSWERS
1. When performing a chemical hair relaxing service on a client with overly porous hair, which
type of relaxer should be selected to ensure safety and efficacy?
A. Sodium hydroxide
B. Ammonium thioglycolate
C. Lithium hydroxide
D. Guanidine hydroxide
Answer: B
Conceptual Explanation: Ammonium thioglycolate (ATG) relaxers have a lower pH and
are milder than hydroxide relaxers, making them more suitable for porous or damaged
hair.
2. Which layer of the skin is primarily responsible for the strength, form, and flexibility of the
skin, containing the majority of the skin’s collagen and elastin?
A. Stratum corneum
B. Papillary layer
,C. Reticular layer
D. Stratum germinativum
Answer: C
Conceptual Explanation: The reticular layer is the deeper layer of the dermis that
supplies the skin with oxygen and nutrients and contains the dense network of collagen
and elastin fibers.
3. In the state of Florida, what is the specific requirement for disinfecting non-porous tools
that have come into contact with blood or body fluids?
A. Washing with soap and water then drying
B. Immersion in an EPA-registered hospital-grade disinfectant with bactericidal, virucidal,
and fungicidal properties
C. Wiping with 70% isopropyl alcohol for 30 seconds
D. Placement in a UV light sanitizer for 20 minutes
Answer: B
Conceptual Explanation: Safety regulations require a hospital-grade, EPA-registered
disinfectant that is effective against a broad spectrum of pathogens when blood exposure
occurs.
, 4. During a permanent wave, the disulfide bonds are broken through a chemical reaction
called:
A. Oxidation
B. Lanthionization
C. Reduction
D. Polymerization
Answer: C
Conceptual Explanation: Reduction involves the addition of hydrogen or the removal of
oxygen; in perming, the addition of hydrogen breaks the disulfide bonds.
5. Which of the following nail disorders is characterized by an inflammation of the nail matrix
followed by shedding of the natural nail plate?
A. Onychia
B. Onychophagy
C. Onychomadesis
D. Onycholysis
Answer: A
Conceptual Explanation: Onychia is an inflammation of the nail matrix, typically caused
by bacterial infection, which can lead to the loss of the nail.
