While there have been several improvements in hair restoration in the last two decades, the introduction of follicular units in hair restoration surgery and the oral medication finasteride are two of the most notable contributions in the field.
One of the biggest complaints about early hair restoration surgery was the appearance of visible plugs or “doll’s hair” in the transplanted area. This unnatural result was due to a single graft containing 15 to 25 or more hairs being transplanted in rows on the scalp. Now, advances in hair restoration surgery have led to the use of follicular units containing small bundles of one to four hair follicles.
There are two methods of harvesting donor follicles – follicular unit transplantation (FUT) and follicular unit extraction (FUE).
In follicular unit transplantation (FUT), the surgeon takes a strip of permanent donor hair from the back of the head, which are then divided up microscopically (so as not to damage them) by a team of highly trained technicians.
In follicular unit extraction (FUE), the specially trained hair restoration surgeon extracts individual follicular units directly from the patient’s donor area (usually at the back of the scalp or nape of the neck where scarring is less noticeable) and transplants them directly into the scalp or further divides them into smaller units before transplantation.
Today’s grafts can better imitate the manner in which hair grows naturally, resulting in a more natural, undetectable outcome. In addition, continual improvements in the instrumentation and techniques used for follicular unit extraction and transplantation, including robotic assisted FUE, may further enhance the results of hair restoration surgery in the future.
Approved by the U.S. Food and Drug Administration (FDA) in 1997, finasteride 1mg (Propecia) is the only oral medication approved for the treatment of male pattern hair loss. Practice Census Report, visit http://www.ishrs.org/mediacenter/media-statistics.htm.
