Jan. 4, 2000 (Atlanta) -- According to the American Academy of Facial Plastic and Reconstructive Surgery, hair loss affects two out of three men, and one in five women. But that doesn't have to be the end of it, thanks to the evolution of hair replacement techniques.
In a study in the recent issue of the Archives of Facial Plastic Surgery, Stephen C. Adler, MD, and Daniel Rousso, MD, compared aesthetic improvement, effectiveness, amount of postoperative pain, and complications of past and present techniques. According to their results, hair restoration procedures overall just keep getting better.
The main objective of the study was to actually prove that newer techniques are better than older techniques, Adler tells WebMD, and also to give patients a voice. "It's important, because as doctors we can always have an opinion of our own work and, yes, we can see that we have improved the hairline, the density, the scars by the new techniques. But basically its our own subjective opinion, and this is actually the first time that the patient's opinion based on an objective evaluation is actually performed and sufficiently proven," he says.
According to Adler, this type of study is not only important for hair restoration, but also for other procedures like facelifts and laser peels. He predicts the research will generate a wave of similar studies.
The researchers sent out 300 surveys to patients who had undergone hair replacement over the last three decades. Of that group, 66 responded, with an average age of about 44. The patients were grouped into three segments depending on when the surgery was done: before 1980, 1981-1990, and 1991-1996.
First, definitions of some terms and techniques are in order. For any hair replacement to occur, some hair is needed from a donor site. A totally bald person is out of luck. According to the authors, the science of hair grafting reaches back to the early 1800s. But the procedures commonly associated with hair replacement didn't begin in the U.S. until the next century.
Adler and Rousso focused on standard grafts (8-10 hairs per follicle), minigrafts (about 4 hairs per follicle), and micrografts (1-2 hairs per follicle). They also focused on scalp reduction, in which a piece of scalp is removed and the parts with hair are stretched over it; flaps, in which a section of hair-bearing scalp is partially disconnected to replace a bald part; strip harvesting, in which a strip of the scalp is entirely disconnected and moved to a bald spot, or punch harvesting. The "punch" method is the oldest method, wherein pencil eraser-sized plugs are removed and placed where needed, giving a person, as Adler describes it, a "doll's head" appearance.
