Hair transplant surgery is outpatient procedure that is performed under local anesthetic. A very thin strip of hair is removed surgically from the back of the head by the surgeon from an area where you have plenty of density. The surgeon and technicians then divide the hair follicles. Next, they transplant thousands of individual hairs onto the scalp in areas that are thin or have no hair. Pain is minimal Most hair transplant recipients begin to see hair regrowth three to six months after the procedure and the hair that grows in is permanent.
