In which method of electrolysis does the client only feel a tiny "flash" of heat?

The method of electrolysis where the client only feels a tiny "flash" of heat is thermolysis. This technique utilizes high-frequency electrical currents to produce heat that destroys the hair follicle. The sensation experienced during thermolysis is typically described as a quick, mild warmth, which is often likened to a brief flash rather than a continuous sensation. This is due to the rapid delivery of energy focused on a small area, allowing for effective hair removal with minimal discomfort.

In thermolysis, the energy is sufficient to effectively target the follicle while generally being comfortable for the client, which distinguishes it from other methods where sensations may be more intense or prolonged. Understanding how each method operates helps to appreciate why thermolysis is associated with such a specific sensory experience.
