A hair transplant (also called hair restoration or hair implantation) permanently restores the hair by transplanting new follicles into balding or thinning areas. Healthy follicles are taken from other areas of the body, most often the back or the sides of the head. This can be done by removing a single strip of skin and hair or removing the follicles individually. The number of grafts needed depends on the patient and the size of the area being treated. A typical surgery involves anywhere from 1,000 to 3,000 grafts.
