Which hair transplantation techniques are offered today?
There are currently two methods of hair restoration that are commonly used and widely regarded as the best methods available. With both of these methods, the basic concept is the same: healthy follicles, which are genetically resistive to balding, are harvested from selected areas of the scalp. They are usually taken from the sides and back of the head. The area where the healthy follicles are taken from is called the “donor site”. These healthy follicles are then methodically transplanted into the area of hair loss, called the “recipient site”.
The differences between the methods are the way in which the FUs, also called grafts, are harvested from the donor area. FUT removes a thin strip of hair from which the FUs are separated and prepared for implantation. FUE uses a small cylindrical punch which removes each FU individually for checking and preparation. The grafts are prepared, ready to be placed over the area of hair loss.
In FUE, individual groupings (graft units) are extracted using a surgical punch tool. The punch tool is positioned over the hair where it emerges from the scalp, then aligned with the direction of the hair growth and inserted, creating a round incision. Whether the incision was created manually or by motorized assistance, the graft unit is extracted by hand.
In this method, a linear incision is made along the back of the head to remove a thin strip of scalp. This strip is then dissected under a microscope to harvest the healthy follicles and prepare them for transplantation into the recipient site. This method is also sometimes referred to as follicular unit grafting (FUG) or more casually, “the strip method” of hair restoration. After the donor strip is removed, the incision is carefully sutured closed.
