Hair transplant is surgical procedure wherein hair roots are harvested (removed) from the back and/or, sides of the head (in some cases from beard and chest also) and planted in the required area (bald area).
Sides and back of the head are considered a permanent zone that means hairs in these areas are permanent and remain intact life long. Transplanted hairs maintain all qualities of the donor area ( from where hairs were removed), including color, texture, thickness, and life of hair also. So, transplanted hairs are also permanent.
The best donor area of hair roots for hair transplant is head (back and sides), followed by beard and chest in that order of preference.
Indications of hair transplant:
When hair roots are harvested from any part of the body other than scalp (head) example - chest, beard, back, limbs, abdomen and pubic area and transplanted to the bald area of the head, it is known as body to head hair transplant. These hairs are not the first choice but selected when a patient has advanced baldness and hairs in the donor area of scalp and beard are not sufficient to cover the bald area. Growth rate and thickness are less in body hairs as compared to scalp hairs. Hairs from the body should be harvested with FUE technique and not with FUT because the later will leave a significant visible scar at the donor site
