The Thermolysis Electrolysis Method or Shortwave Diathermy Method or Radio-frequency Method.

In this technique alternating current is passed through the needle which heats up the needle inserted into the root of the hair. A fine wire probe is used to transmit radio waves to tissues near the probe. Radio Frequency Diathermy (The therapeutic generation of local heat in body tissues by high-frequency electromagnetic currents) or Short Wave Electrolysis.  Molecules within the tissue are caused to vibrate which lead to a rapid increase of the temperature, causing coagulation (to change or be changed from a liquid into a thickened mass: egg white coagulating when heated; blood clotting over the wound) of the proteins within the follicle, effectively killing the follicle. The heated needle produces bubbles of the water which loosens the root and kills the germinative cells of the hair root to produce removal of the hairs.

Thermolysis is much faster than galvanic electrolysis and requires only a few seconds. In high-speed “flash” thermolysis the higher energy current is applied for only a fraction of a second. The flash method is best used with insulated needles, which protect the upper hair follicle and permit higher energy directly into the lower follicle. This method is not suitable for coarse hairs and may have a slightly higher risk of skin damage.
