Electrolysis is the use of electricity to remove hair. Short-wave electric currents are applied to the skin to destroy the roots of the hairs. This will remove the hair from the skin and stop it from re=growing. It can be used medicinally or cosmetically. The procedure is generally safe so long as it is being performed by a trained operator. The most dangerous area to perform electrolysis is around the eyes and should only be performed if absolutely necessary. Electrolysis of the legs is rarely carried out because of the length and cost of the procedure. It is not recommended for use on large parts of the body.

Electrolysis destroys the hair follicle and new hair therefore cannot grow. There is no other significant damage to the skin however. It is still recommended that cosmetic use of electrolysis be used sparingly as it is a significant medical procedure and all such procedures carry risks.
