The beauty of this dermatological treatment is that it targets the follicle, not the hair. By zapping the follicle deep at its base it deactivates the hair growth. This doesn't happen in just one treatment. It will take several. But over time the hair will grown back lighter and more sparse until it stops growing for good. Pricing will vary as it is based on many factors such as the thickness of the hair and the area being treated. But whatever the price, a permanent solution is worth it.
