This paper deals mainly with histologic findings and clinical aspects of epilation using insulated needles. Patients were checked for hair regrowth after "thermolysis" epilation--a cycle of three to four treatments at roughly 3-month intervals, within an observation period of 2 1/2 years. The results for 39 patients, compiled 6 months to 1 year after the final epilations, showed almost no or extremely reduced hair regrowth with almost no scarring.
