Hair removal electrolysis, a permanent hair removal technique, involves the insertion of a fine needle into the hair follicle, followed by the application of an electric current. This process destroys the follicle's ability to produce hair.
Electrolysis is a safe and effective method of removing unwanted hair, and its results are considered permanent. It is commonly used to remove hair from the face, underarms, and bikini line. The procedure was first introduced in the 1870s and has since been refined to become a widely accepted and effective hair removal technique.
