What hair removal method utilizes heat as part of the process?

Electrolysis is a hair removal method that utilizes heat as part of the process. It works by using an electric current to generate heat within the hair follicle, effectively destroying it and preventing future hair growth. This method is particularly effective for permanent hair removal since it targets the hair at the root level.

In contrast, waxing involves the application of warm wax to remove hair from the follicle, but it does not rely on heat generated by a current to achieve results. Shaving simply cuts the hair at the surface without any effect on the follicle, and threading is a technique that uses a twisted thread to remove hair, also without employing heat. Hence, electrolysis is distinct in its utilization of an electrical current to produce heat as a means to effectively and permanently remove hair.
