1. What is the primary purpose of electrolysis in hair removal?
To permanently destroy the hair follicle
Electrolysis uses electrical current to destroy the follicle’s growth cells,
preventing regrowth.
2. Which modality uses direct current to produce sodium hydroxide for hair
removal?
Galvanic electrolysis
Galvanic electrolysis causes chemical decomposition in the follicle via lye
formation.
3. What type of current does thermolysis use?
Alternating current (AC)
Thermolysis uses high-frequency AC to generate localized heat in the
follicle.
4. The blend method combines which two modalities?
Galvanic and thermolysis
The blend combines chemical destruction from galvanic and heat from
thermolysis.
,5. What is the active growing stage of the hair cycle?
Anagen
Anagen is when the hair is actively growing and most susceptible to
destruction.
6. Which hair growth stage has the least pigment in the hair shaft?
Telogen
Telogen is the resting phase with minimal pigment, making it less
responsive to treatment.
7. In laser hair removal, which chromophore absorbs the laser light?
Melanin
Melanin in the hair shaft absorbs laser energy and converts it to heat.
8. What is the principle that explains how laser light destroys the follicle
without damaging surrounding tissue?
Selective photothermolysis
Selective photothermolysis targets specific chromophores while sparing
nearby structures.
9. Which laser wavelength penetrates deepest into the skin?
1064 nm Nd:YAG
Longer wavelengths like Nd:YAG penetrate deeper, making them suitable
for darker skin types.
10.What safety device must be used by both operator and client during laser
treatments?
Protective eyewear
Eye protection prevents retinal or corneal damage from laser exposure.
, 11.The unit of laser energy is measured in:
Joules
Laser energy output is quantified in joules, representing energy per pulse.
12.The fluence in laser treatments is measured in:
Joules per square centimeter (J/cm²)
Fluence measures the energy delivered per unit area of skin.
13.Which Fitzpatrick skin type has the highest risk of post-inflammatory
hyperpigmentation with laser?
Type VI
Darker skin has more melanin, increasing the risk of pigmentation
changes.
14.Which electrode is inserted into the follicle during electrolysis?
Probe
A fine probe delivers the electrical current directly to the follicle’s base.
15.Which metal is commonly used for disposable probes in electrolysis?
Stainless steel
Stainless steel is durable, conductive, and resists corrosion.
16.What is the main purpose of using a cooling device in laser hair removal?
To protect the epidermis
Cooling protects the skin’s surface from thermal damage during laser
treatment.
17.What is a contraindication for laser hair removal?
Photosensitive medications
