Permanent hair removal uses laser or electrolysis technology to disable hair follicles so they no longer produce new hair. Laser systems target pigment in the hair shaft, while electrolysis uses electrical current to destroy individual follicles. Most people see significant reduction in hair growth rather than absolute removal of every hair, and results can last for years or permanently, depending on the method and individual factors.

Permanent hair removal works best on people with darker hair and lighter skin, since most laser systems rely on contrast between hair and skin. However, newer laser technologies and electrolysis can be adapted for various skin tones and hair colors. A qualified provider will assess your skin type and hair characteristics to recommend the most effective option for you.

Laser sessions typically last 15 to 60 minutes depending on the area being treated. You will wear protective eyewear, and the technician will pass the laser handpiece over the skin, which may feel warm or cause mild discomfort similar to a rubber band snap. Electrolysis is slower, treating one follicle at a time, and sessions often take longer.

Most people return to normal activities immediately after laser treatment. The treated area may appear slightly red or swollen for a few hours. Avoid direct sun exposure and follow your provider's guidance on skincare in the days following treatment.

Hair typically begins to shed within one to two weeks after treatment. Multiple sessions spaced four to eight weeks apart are usually needed to achieve desired results, since hair grows in cycles. Results can last years or indefinitely, though some regrowth may occur over time.
