Thermolysis hair removal treatments work by applying alternating current to excite water molecules within the follicle. As these molecules vibrate, they produce enough heat to disable the growth cells, ultimately preventing future hair production.
Because the process is fast and requires only a few steps, an electrologist can treat each hair in just seconds and work efficiently across many follicles. Depending on the treatment approach, the electrologist may apply a higher‑intensity current for a shorter duration or a lower‑intensity current for a longer period.
