During a  Hair Transplant  , a physician moves hairs from an area of thick growth to bald areas. Most  Hair Transplant  are performed in an office setting under local anesthesia. You should only experience minimal pain. After thoroughly cleaning the scalp, the surgeon uses small needles to numb an area where there is normal hair growth on the back of the scalp. A portion of the hairy scalp is then removed with a scalpel and set aside. The scalp is sewn closed.
