Which hair removal method involves the use of heat to destroy hair follicles?

The method that utilizes heat to destroy hair follicles is thermolysis. In this process, a high-frequency current generates heat which is applied directly to the hair follicle, effectively coagulating the tissue within it. This heat disrupts the follicle's ability to produce hair, leading to permanent hair removal over successive treatments.

Unlike other methods, such as shaving which merely cuts hair at the skin's surface, or epilation, which pulls hair from the roots but does not necessarily destroy the follicle, thermolysis specifically targets the follicle itself. Additionally, depolarization refers to a process generally related to the nervous system and is not associated with hair removal techniques. This makes thermolysis a unique and effective approach in permanent hair removal solutions.
