Which technique is typically used to extract hair during electrolysis?

• A. Laser energy application
• B. Chemical depilatory agents
• C. Electrical current
• D. Heat application

Answer: (C)

Electrolysis is a hair removal method that specifically utilizes an electrical current to remove hair. The process involves inserting a very fine probe into the hair follicle, through which a small electrical current is delivered. This current destroys the hair's growth cells by generating heat within the follicle, effectively causing the hair to fall out. In contrast, techniques such as laser energy application, chemical depilatory agents, and heat application focus on different methods of hair removal. Laser treatments target melanin in the hair using focused light energy; chemical depilatories dissolve hair at the skin's surface; and heat application methods, like thermolysis, may use radio frequency to achieve similar effects but are not characteristic of electrolysis itself. Therefore, the use of electrical current is the defining characteristic of electrolysis that makes it effective for permanent hair removal.
