Thermolysis is the correct response as it employs a thermal effect generated by high-frequency electrical currents to achieve permanent hair removal. In this process, the heat produced destroys the hair follicle by rapidly heating the surrounding tissue, leading to the denaturation of the hair's proteins. This method is effective in permanently disabling hair growth.

In contrast, galvanic involves a chemical process where DC current is employed to create a chemical reaction in the hair follicle, rather than directly using heat. Electrolysis is a broader term that encompasses both galvanic and thermolysis methods; however, it typically refers specifically to the use of direct current. Photoepilation employs light energy rather than thermal effects, targeting pigments in the hair for destruction, which differs fundamentally from the heat-centric approach of thermolysis. Understanding these distinctions clarifies why thermolysis is specifically associated with the thermal effect of current for hair removal.
