Thermolysis Electrolysis is one of the three different types of electrolysis styles practiced by electrologists around the world. Thermolysis Electrolysis is when a AC (or short wave) current passes through the needle causing vibration in the water molecules surrounding the hair follicle which produces heat. (Similar to the principle behind a microwave oven.) The heat damages the hair follicle. This method is much faster than Galvanic or Blend in that larger areas can be cleared at one treatment. Also, it is considered the most comfortable method.
