Hair transplantation involves excising a "donor area" from the back of the scalp and then relocating micro-grafts from this donor area into the patient's thinning or bald region. Tiny holes are made in the bald region with carbon steel instruments and the micro-grafts are manually placed into these openings. Each micro-graft contains one or two hair follicles; approximately 700 grafts are implanted per hair grafting session. It may take several sessions to achieve the amount of thickness you desire. In addition, you must have areas of thick hair in order to have hair grafting. Individuals without hair are not candidates for this procedure.
