What method of hair removal uses electrical current to destroy hair growth cells?

Electrolysis is the method of hair removal that utilizes electrical current to target and destroy the hair growth cells. This process involves inserting a fine needle into the hair follicle, where a small amount of electrical current is delivered. This current effectively destroys the vital cells necessary for hair growth, leading to permanent hair removal over time.

In contrast, laser hair removal is a method that uses focused light energy rather than electrical current to target hair follicles. It works by heating the pigment in the hair to damage the follicle, but it doesn't specifically destroy the growth cells in the same way as electrolysis. Photoepilation, which is often synonymous with laser hair removal, uses similar technology but generally refers to various light-based methods of hair removal that also target the hair pigments. Waxing, on the other hand, is a temporary hair removal method that removes hair from the root using a sticky substance, but it does not affect the hair growth cells directly. Thus, electrolysis is uniquely effective for permanent hair removal due to its specific mechanism of action using electrical current to destroy these cells.
