For over 130 years electrolysis has been ans still is the only 100% permanent hair removal method. This technique permanently destroys germinative cells responsible for hair growth by sliding a fine probe in to the hair follicle and applying a current adjusted to the type of hair and the area to be treated.
People ask why electrolysis instead of laser? Laser tends to treat large areas of skin using a light based lamp or a laser, which can reduce hair growth, but not permanently remove hair like electrolysis. After a course of electrolysis treatment the results are complete, permanent hair removal.
