If the hair restoration is started early enough, the young patient need never feel the stigma of being bald for very long at all. A doctor who is skilled in doing hair transplant procedures on young people will do some investigation before tackling such a project. If you put pressure on the area, the bleeding will usually stop. In rare situations, the bleeding does not stop this way. In that case, it might be necessary for the surgeon to do some extra stitching to close the wounds. 3. Pain. There is actually very little pain with hair transplant surgery. About half of the people who have the procedure done will not need any pain relievers at all. It may seem odd, but once the grafted hairs are set, they are just as strong as the rest of your hair. You can cut them, comb and brush them, and even dye them in time. New hairs start to grow within three months. You will find you need haircuts more often, as your hair will grow about one or two centimeters per month. 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. All that remains is to measure your balding area and multiply the number of square inches by 156. When you know what number of grafts to expect during your hair transplant surgery, you will be a savvy consumer. 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. These plugs were inserted into the balding area. Now, a multi-bladed knife can be used to cut long thin strips of donor tissue.
