Electrolysis is also a FDA approved permanent method of removing individual hairs from the face or body. The process works by inserting an epilator device into the skin using shortwave radio frequencies in hair follicles to stop new hair from growing. This damages your hair follicles to prevent growth and causes existing hairs to fall out. However, you’ll still need multiple follow-up appointments for the best results. Ideal for individuals that are not candidates for laser hair removal like women or men with blonde, red or gray hair.
