Inserting a single needle into a hair follicle for hair removal is called what?

• A. Thermolysis
• B. Galvanic electrolysis
• C. Blend method
• D. Waxing

Answer: (A)

Thermolysis relies on delivering a high‑frequency current through a fine needle that is inserted into the hair follicle. The energy quickly heats the follicle, causing rapid coagulation and destruction of the hair matrix cells that drive hair growth. Because the heating is targeted and fast, this method is efficient when a single needle is used, making it a common and effective approach for electrolysis-based hair removal. In contrast, other approaches rely on different mechanisms: galvanic electrolysis uses direct current to create a chemical reaction inside the follicle (lye) and typically involves multiple steps or electrodes; the blend method combines both heat and chemical action; waxing removes hair from the surface and does not destroy the follicle. The single-needle, rapid heating characteristic is what distinguishes thermolysis as the method described.
