A doctor who has done many successful hair transplant procedures will have a list of people willing to talk about their experience. You can call each one and ask about how the procedure went for them. Be aware that not all hair transplant doctors are scrupulous businesspeople. Many will try to fool you into believing they are more experienced than they are. Follicular units are then extracted from the tissue using a stereomicroscope. This is all done by skilled nurses and technicians. The insertion of the hair into the receptor sites comes later. Once the follicular units for the hair transplant are dissected out of the donor tissue, technicians set them aside in a saline solution. Some of the available cells go through several stages before ending in cell death in a very short time. These cells would not be adequate for use with hair transplant surgery. There seem to be other cells which last longer and would work for this application. A scientist named Dr. Gho has done some work and acquired a Dutch patent on his work with hair multiplication. Its width should be no more than one centimeter in most instances. This allows the scalp to close completely when sutured back into place. If the hair transplant procedure is done well, the scar will not be noticeable even if the patient likes to wear his hair in a short style. The scar will only become unsightly if the patient is genetically predisposed to keloid scarring. One trick of doctors, who work to give young people hair transplant surgeries, is to guide them in setting the hairline. A young person will usually want a fairly low hairline. He remembers the way it was just a few short years ago and wants to duplicate the image. A good hair transplant surgeon will discourage a low hairline. Scar revision surgery is usually done at a flat fee, perhaps around $1000 for the procedure. The normal hair transplant procedure will cost differently depending on the number of grafts even though the cost per graft goes down the more grafts you have. For example, 100 grafts may cost you $1500, while 3000 grafts may cost about $12,000.
