Up-to-date techniques for hair transplant use only the follicular unit and not a large amount of surrounding tissue for the donor grafts. This cuts down considerably on the amount of pain experienced. The procedure is minimally invasive now, so that no more of the scalp is disturbed than is necessary. 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. There is a very small percentage - about 5% of all women with baldness problems - who are good candidates for hair transplant surgery. The thing that all these women have in common is that they all have healthy areas of hair follicles that can be used as donor sites. For example, women with mechanical or traction Alopecia have lost their hair because they have scratched their head for a long period of time, they have used tight rollers or their hair has been pulled or stretched in any manner. 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. Most others take a mild pain reliever such as Tylenol for a few days, and that seems to be enough for them. The follicular unit is a living unit with muscle, nerves and blood vessels that are all tiny enough to fit into this small package. The unit is set off by a band of collagen that holds it together. If you look under a microscope at a scalp, you can see follicular units growing in just this way. The idea of bringing this information into hair transplant procedures led to innovative surgical methods. Once the follicular units for the hair transplant are dissected out of the donor tissue, technicians set them aside in a saline solution. The temperature must be ideal or the small grafts will not survive the procedure. This is done very carefully in order to ensure a good result. The surgeon will make tiny incisions into the scalp where the hair transplant grafts are to go.
