Mega-sessions where thousands of grafts are done in one sitting help to shorten the overall time. However, the length of these sessions is often grueling. 5. Hair transplant surgery may be combined with other procedures. If you do not have enough hair, you cannot have a normal hair transplant surgery. Coarse hair will cover more area. When your hair transplant is done, the surgeon will be able to use fewer hair follicles per graft if your hair is coarse. That is because coarse hair provides more coverage. However, finer hair will tend to look more natural, if thinner. 5. Straight hair does not cover scalp like curly hair does. These are called stable sites because they remain unchanged over time rather than shrinking like the hair follicles affected by DHT do. Female pattern baldness is different. In most cases, they do not have large areas of stable balding-resistant hair follicles. The sides and back of their hair tends to thin just as the front and top of the head do. This method keeps the units intact and ready to transplant. Earlier methods such as mini-grafting and micro-grafting broke up the follicular units. As a part of the hair transplant process with Follicular Unit Transplantation (FUT), a new microscope technique was used. It is called stereomicroscopic dissection. 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. If they do feel any pain, it is of a degree that can be taken care of with a few doses of Tylenol. On the other hand, some people who have had hair transplant procedures done do not feel that there is any pain involved at all. They tolerate the injections of the local anesthetic well. They are not bothered at all by the procedure.
