Electrolysis is a method of hair removal that specifically utilizes an electric current to destroy the hair follicle. This process involves inserting a fine probe into the hair follicle where an electric current is applied. The current either heats or chemically alters the follicle in a way that inhibits future hair growth, making it a targeted and effective long-term solution for hair removal.

In contrast, laser hair removal uses focused light energy rather than electric current to target and destroy hair follicles, making it distinct from electrolysis. Threading is a manual technique that involves using a twisted thread to pull hair from the follicle, and it does not employ any form of electric current. Similarly, waxing is a process that uses a sticky substance to remove hair from the root but also does not involve electricity in any way. Hence, electrolysis is the only method listed that relies on the application of an electric current for hair removal.
