Which technique is categorized by the FDA and the AMA as permanent hair removal?

• A. Electrolysis
• B. Laser hair reduction
• C. Waxing
• D. Depilatory cream

Answer: (A)

Electrolysis is the technique categorized as permanent hair removal because it directly destroys the hair follicle with electrical energy. A fine needle is inserted into the follicle and energy is delivered to disable the follicle’s ability to grow hair in the future. Once the follicle is permanently damaged, regrowth is unlikely, which is why multiple sessions are used to treat all hairs in their growth cycles. In contrast, laser hair removal targets pigment in the hair but is considered long-term reduction rather than permanent removal, and waxing or depilatory creams remove hair from the surface without harming the follicle, so hair returns.
