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. They used hair from the fringe, or back and sides of the head, to accomplish this. The most important thing to remember is that you need hair for the hair transplant to your balding areas. The hair has to come from somewhere on your body. Wherever you take the hair from is called the donor site. There can be different donor sites for different people. The most common donor site for hair transplant surgery is on the head. He will try to get the patient started by stating that the price will be very low. He will know all along that the procedures will cost much more, but he will lowball the price anyway just to get the patient started so that they have to finish. 3. Creating Scars. All hair transplant surgery will create small scars. However, with the micro grafts on the leading edges, they blend in and give the hair fullness. They serve an important function. Previously, when hair plugs were used, doctors did the hair transplant surgeries much differently. They used an instrument called a trephine to cut circular grafts from 2mm to 5mm in diameter. 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. 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. The way your hair color compares to your skin color will have an effect on the look of your hair transplant. If you have a hair color that is similar to the color of your skin, you are in luck. Your scalp will not betray any lack of coverage that happens to be present. If, on the other hand, your hair and skin color contrast distinctly hair follicles show up more.
