A hair transplant is the transference of hair grafts from a donor region to another region affected by normal male pattern hair loss or female pattern hair loss. This is done by removing a strip of hair-bearing scalp from the back or sides of the head where hair growth is permanent and not affected by Dihydrotestosterone. The most common donor area is from the back of the head, rather than the sides. This strip of hair bearing scalp can vary greatly in size but, as an example, can measure 1-2 cm wide and 10 or more cm long. After it is removed, the doctor will close the donor area with sutures. These will need to be removed in approximately seven days.
