Electrolysis is the only clinically recognised form of permanent hair removal available. It was developed by Dr Charles Michael, an opthamologist, in 1875. The treatment involves inserting a small, flexible, sterile needle into each hair follicle and applying negative galvanic current. This then destroys the hair follicle. The treatment can be done anywhere on the body and can treat any colour skin and hair colour. Treatment length can vary depending on the area treated and hair cycle of the individual.
