Okuda of Japan was busy trying to transplant hair to the eyelashes and eyebrows of people who had lost them traumatically. 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. 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. Sometimes, they will try to make you believe they do better work than they do. Since the young patient will be dealing with this problem for a long time, this is a necessary consideration. When the hair transplant surgeon achieves a higher hairline, he will be able to get more fullness on the top of the head because he has less to cover. This is not to say the young person will have a receding hairline when the procedure is complete; just that the hairline will not be too low. Based on the fact that the average Caucasian male has a density of 2 hairs per millimeter, it can be assumed that the average density of hair is 1250 hairs per square inch. Figuring at an average of 2 hairs per follicular unit, it would take 625 follicular units per square inch. To get 25% of that, you would need 156 follicular units per square inch. You will also need to reveal to the doctor if you have had any hair replacement surgery before. To get an idea of how you will react to having a hair transplant procedure done, the doctor will ask many questions. He will want to know the basics of your lifestyle as they relate to your health and hair. Some finance companies are geared especially to people who are getting cosmetic surgery.
