Because losing hair at such a young age is very traumatic, hair transplant doctors do not like to go along with the patients' snap decisions. After an in-depth consultation, the doctor will do everything in his power to put off the surgery. He will ask the patient to come back for a final consultation in six months or so. This was before World War II. When the war broke out, his discovery of hair transplant procedures was squelched until two decades later. In 1959, Dr. Norman Orentreich began a new field of surgery when he published on the use of hair transplant surgery. It was during this decade that doctors had begun to try moving balding-proof hair follicles to the balding areas of patients' heads. Male pattern baldness uncovers parts of the top of the head. However, the sides and back of the head are usually covered with healthy balding-resistant hair follicles. Men with this pattern of balding will have donor hair that survives the hair transplant process and flourishes long afterward. That is because a naturally-occurring enzyme in the body combines with testosterone to create a chemical called DHT. They might show you photos that they have taken using lighting tricks to make the hair look thicker and healthier than it is. It is often hard to spot such tricks, but knowing that some surgeons do them will help you to watch out for them. You will get some good advice if you go to certain associations for assistance. 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. It is unclear whether this is much like hair cloning or not. You should figure that the average number of hair transplant grafts needed to cover a balding area is 25% of the original hair that was there. You can move up or down from this figure according to your other factors such as thickness, curliness, or color. Then, you can use this number to figure up the grafts needed.
