Hair transplant surgery is based on the principle of donor dominance, which means that hair from healthy donor sites will take root and grow normally when transplanted into balding, recipient sites. Hair transplantation involves:
- Removing small strips of hair-bearing scalp from the back and sides of the head, known as the “donor region,” which contains hair that will grow throughout a lifetime
- Repairing the donor region, usually resulting in a very narrow scar which is hidden by overlying hair
- Harvesting strips of hair-bearing scalp and dividing into grafts for placement in the balding areas
The amount of coverage varies depending on the extent of baldness and the specific procedure performed. Within one month, much of the transplanted hair is shed. About two months later, hair starts to grow and continues to grow at a normal rate. After six months, the transplanted hairs begin to take on a natural appearance.
