Abstract
A new method and apparatus for the long-term removal of hair are provided. Ultrasonic energy is transmitted to a needle passed through the skin into an individual hair follicle. The resulting cavitation of the area surrounding the hair follicle causes the hair follicle to be disrupted. The process is repeated for individual hair follicles over the selected region of the body.
