What method is used in hair removal known as Thermolysis?

Low frequency current
High frequency current
Chemical depilatories
Laser technology

The correct answer is: High frequency current

Thermolysis is a method of hair removal that utilizes high frequency current to produce heat in the hair follicle, effectively destroying it. When high frequency electrical energy is applied to the skin, it generates heat through a process called impedance. This heat is localized, allowing for precise targeting of individual hair follicles. As a result, thermolysis is an effective method for permanent hair reduction, particularly in delicate areas of the body. This technique contrasts with methods like low frequency current, which do not generate the same level of heat necessary to achieve permanent hair removal. Chemical depilatories work by dissolving hair at the skin's surface rather than targeting the follicle itself, and laser technology employs light energy rather than electrical current. Hence, the unique ability of high frequency current to create sufficient heat to damage hair follicles makes it the correct choice for thermolysis.
