For removal of hairs, usually by electrolysis (catholysis), a fine metal probe is brought into contact with the base of a hair and a direct electrical current is passed through. Chemical changes caused by the current in the vicinity of the probe tip cause the hair follicle to die. The probe forms the negative electrode (cathode) and the positive electrode is attached to the skin nearby. The positive electrode has a large surface area so that the current density beneath it never reaches toxic levels. The same instrument may sometimes be called an electrolysis unit, catholysis unit, or epilation unit.
