Electrology is the only method of permanent hair removal approved by the FDA, utilizing three primary techniques. Each technique involves inserting a small, rounded-tip metal probe into the hair follicle and applying a slight electric current to demolish the follicle’s ability to create hair. Unlike the needles used for medical procedures, electrology probes are specially designed to avoid puncturing the skin. The insertion is typically painless as they are inserted into natural openings of hair follicles. There are varying opinions on which modality technique is most effective and least damaging to the skin. However, it is generally observed that while all modalities are effective over time, some like flash, have higher regrowth rates and may require repeated treatments, potentially leading to more skin damage. At ZAP, I primarily use galvanic electrolysis and the blend method. For clients that are sensitive to direct current, I may use manual thermolysis. Due to it’s efficiency and reliable results, I prefer to recommend the blend method for surgical preparation.
