Galvanic electrolysis is most accurately referred to as the single needle method. This technique utilizes a direct current to apply a chemical reaction to the hair follicle, effectively destroying it. In this process, a single, fine needle is inserted into the hair follicle, allowing the electrical current to flow directly into each hair root. This method is known for its precision, targeting individual hairs, and is often associated with permanent hair removal.

While the multiple needle method pertains to electrolysis, it specifically refers to a different technique that uses several needles simultaneously to treat multiple hair follicles at once. The thermal method typically refers to procedures that use heat, while the laser method utilizes focused light rather than electricity. Understanding these distinctions is essential for grasping the different approaches within hair removal techniques in esthetics.
