Traditional hair restoration surgery involves removing hair-bearing strips of the scalp from the back and sides of the head, which are then transferred to areas of baldness at the top of the head or along the hairline. The portion of the scalp from which the follicles were removed must be sutured closed, leaving a prominent scar. Not only can it be quite noticeable, but this scar can cause a sensation of tightness on the scalp and sometimes even result in numb areas.
