During a hair transplant, a physician move hairs from an area of thick growth to bald areas.Most hair transplants 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.

As a patient ages, some hairs randomly begin to miniaturize (shrink in length and width) in each follicular unit.in most people, the donor zone retains enough permanent hair that hair transplantation is a viable procedure even for a patient well into his 70's.
