1. What is the primary goal of electrolysis?
A. To temporarily lighten the hair shaft
B. To permanently disable the hair follicle's ability to produce hair
C. To exfoliate the epidermis
D. To increase circulation around the follicle
Answer: B. To permanently disable the hair follicle's ability to produce
hair
Rationale: Electrolysis is designed to achieve permanent hair removal by
applying electrical energy to the follicle and destroying or disabling the
structures responsible for hair growth. Unlike temporary hair-removal
methods such as shaving or depilatory creams, properly performed
electrolysis targets the follicle itself.
, 2. Which three modalities are traditionally associated with
electrolysis?
A. Galvanic, thermolysis, and blend
B. IPL, diode, and alexandrite
C. Waxing, sugaring, and threading
D. Radiofrequency, ultrasound, and cryotherapy
Answer: A. Galvanic, thermolysis, and blend
Rationale: Galvanic electrolysis uses direct current to produce a
chemical reaction within the follicle. Thermolysis uses high-frequency
alternating current to create heat. The blend modality combines
galvanic and thermolysis to use both chemical and thermal effects.
3. What type of current is primarily used in galvanic electrolysis?
A. Alternating current
B. Direct current
C. Pulsed laser energy
D. Infrared radiation
Answer: B. Direct current
Rationale: Galvanic electrolysis uses direct current, which causes an
electrochemical reaction within the follicle. This reaction produces
,sodium hydroxide, commonly called lye, which chemically damages
follicular tissue.
4. What is the primary action of thermolysis?
A. Chemical destruction using lye
B. Thermal destruction using heat
C. Mechanical extraction of the hair root
D. Cooling the follicle below freezing
Answer: B. Thermal destruction using heat
Rationale: Thermolysis uses high-frequency alternating electrical
current to generate heat around the probe tip. When appropriately
delivered, this heat damages follicular structures responsible for hair
growth.
5. What is the purpose of a sterile or properly disinfected probe in
electrolysis?
A. To increase hair growth
B. To prevent transmission of microorganisms
C. To make the hair shaft thicker
D. To reduce the electrical current
, Answer: B. To prevent transmission of microorganisms
Rationale: The probe enters the follicular opening and therefore must
be sterile when required by the applicable infection-control standard.
Proper probe handling helps prevent cross-contamination and
transmission of bloodborne or other infectious organisms.
6. Which structure is primarily responsible for producing the hair
shaft?
A. Sebaceous gland
B. Hair matrix
C. Arrector pili muscle
D. Stratum corneum
Answer: B. Hair matrix
Rationale: Matrix cells at the base of the follicle actively divide and
contribute to formation of the hair shaft. Damage to the appropriate
follicular structures is therefore essential for effective permanent hair
removal.
7. Which phase of the hair-growth cycle is generally considered the
active growth phase?
