What technique involves the use of electrical current to permanently remove hair?

Electrolysis is a method used for the permanent removal of hair by employing electrical current. This technique involves inserting a fine probe into the hair follicle and applying an electric current to destroy the hair root. The process effectively prevents future hair growth, making it a popular choice for individuals seeking long-term hair removal solutions. Unlike other methods, electrolysis treats each hair follicle individually, which is essential for achieving permanent results.

In contrast, laser hair removal operates using light energy rather than electrical current, targeting the pigment in hair follicles. While it can lead to long-term hair reduction, it is not classified as a permanent hair removal solution. Electrotherapy, on the other hand, generally refers to various treatments using electrical currents for skin conditions rather than hair removal. Thermal hair removal typically involves other methods, like laser or intense pulsed light, focusing on heat rather than electrical current. Therefore, electrolysis stands out as the definitive method for permanent hair removal using electrical current.
