What is hair transplant surgery?

 Hair transplantation involves extracting grafts from a donor site, usually the back of the scalp, and transplanting them into the recipient area, the bald area. It can be performed in two ways –

 1. Follicular unit transplant (FUT) in which a strip of hair bearing scalp tissue is harvested from the back of the scalp, individual follicular units cut and then transplanted into the donor area.

 2. Follicular unit extraction (FUE) in which individual hair follicle units are harvested from the donor area using a motorised punching machine, and then these grafts are simultaneously implanted in the recipient area.

 - Flap surgery is more elaborate and involves rotating a flap of hair bearing area to the bald area.

 - In tissue expansion surgery, the hair bearing scalp is expanded using tissue expander, and then the expanded tissue is moved to the bald area.

 - Scalp reduction surgery is simply excising the bald area and suturing together the hair bearing areas on the scalp.
