Thermolysis is the hair removal technique that utilizes thermal current to effectively rid the skin of unwanted hair. In this method, high-frequency electrical currents are applied to the hair follicle, generating heat—hence the name "thermolysis." This heat damages the follicle and impedes future hair growth.

The effectiveness of thermolysis makes it suitable for various hair types and skin sensitivities. Unlike alternatives like galvanic methods, which rely on a chemical process, or electrolysis, which applies a direct current to destroy hair follicles by chemical reaction, thermolysis is quicker as it typically requires less time per hair.

Additionally, while cryotherapy is a method that uses cold temperatures to treat certain skin conditions, it does not involve thermal currents, thus is not relevant to hair removal techniques. Understanding the distinct characteristics of thermolysis helps emphasize its unique application in the field of hair removal.
