Electrolysis for the treatment of hypertrichosis and hirsutism.
There are three electrolysis modalities. In galvanic electrolysis, a direct current is passed down a needle inserted into the hair follicle, destroying the follicle. In thermolysis a high frequency alternating current is passed down the needle and produces destructive heat. The blend is the third modality, which combines galvanic electrolysis and thermololysis. Electrolysis satisfactorily removes hair from women and men with hypertrichosis, but women with hirsutism require concomitant hormonal management. Scarring does not occur with properly performed electrolysis. Shaving one to five days before electrolysis greatly increases efficacy because it ensures that only growing anagen hairs are epilated. The judicious use of ice packs and the recent availability of EMLA (lidocaine/prilocaine cream) have been beneficial in reducing the sensations of electrolysis.
