Slit grafting involves the harvesting of small follicular units containing between 10-15 hairs.
Once the donor harvest has been completed, individual units are refined under high-power magnification. The follicular unit grafts are then inserted into openings made in the scalp.
This technique, in contrast to the traditional punch graft, utilizes higher amounts of smaller grafts. A huge plus for this type of procedure is that no tissue is removed from the recipient bed (the area of the scalp receiving the transplant), making the whole thing less invasive and far less painful. The vascular structure is preserved, resulting in an increased graft yield, meaning chance of the grafts remaining strong and healthy is higher. The doll head look associated with traditional round grafting is typically eliminated, and a more natural hairline is achieved.
