What is the primary purpose of electrolysis in hair removal?

• A. To damage the cells of the papilla and disrupt hair growth
• B. To shave hair at the surface
• C. To bleach hair color
• D. To permanently remove the sebaceous gland

Answer: (A)

Electrolysis works by permanently disabling the hair follicle itself. A tiny probe is placed into the follicle at the base, and electrical current is applied to destroy the dermal papilla—the tissue that nourishes and regulates hair growth. By damaging the papilla and the hair matrix, the follicle can no longer produce a growing hair, which is why this method is considered permanent.

Shaving only cuts hair at the surface and leaves the follicle intact, so it doesn’t affect growth. Bleaching changes the hair’s color without impacting the follicle. Removing the sebaceous gland targets oil production, not hair growth, so it isn’t the goal of electrolysis.
