Electrolysis is the process of permanent hair removal in which the hairs are treated individually. A trained Electrologist inserts a small metal probe into the hair follicle alongside the hair. A small amount of electrical current is then delivered to the probe by a device called an epilator. Depending on the technique used, the electrical current destroys the hair root either by heat or chemical action, or in some methods by both at the same time.

Coarse hairs cannot always be eliminated with one treatment, thus breaking down the hair germ cells may require additional treatments. During the course of treatment and due to the cyclic nature of hair growth, new hairs, as well as hairs emerging from a dormant phase will also be treated and may be visible the same time as finer re-growth hairs.

Electrolysis has a 125 year history of safety and is a great option for individuals who are not a candidate for laser hair removal (i.e. people with extremely dark skin, or someone who has red, blonde or gray hair). Electrolysis is still the best method for shaping eyebrows permanently.
