They used hair from the fringe, or back and sides of the head, to accomplish this. The doctors were trying to determine whether hair follicles were balding resistant because of where they were located on the head or because of something inherent in the follicles themselves. This would settle the issue of whether hair transplant would work by those methods. To calculate the number of grafts you need for hair transplant surgery, there are several factors to take into account. The thickness of the hair shaft makes a difference. Whether the hair is curly or straight determines if the hair will lie flat or stand up, creating more fullness. Another important factor for hair transplant is the color of the hair in contrast to the color of the skin. 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. However, if you feel inferior when you are dealing with new customers or clients, you will likely not do well at your job. A hair transplant procedure could help your career. 3. How do I feel about my hair in social situations? If you are constantly thinking about your hair loss when you are with friends or colleagues, your social life will suffer. However, there are other surgeries that can be used in conjunction with hair transplant to achieve similar results. The difference is that these procedures are generally more painful. 6. The grafts may not survive. Few surgeons will divulge to you the fact that hair grafts do not always survive after hair transplant surgery. Hair cloning promises to be a revolutionary procedure that would give people with little hair a chance to have hair transplant surgeries. It would do this by multiplying the hair a patient already has rather than using up the good hair that still exists on the patient's head. Hair cloning is done by taking stem cells, or dermal papilla cell, and cloning them in a laboratory setting.
