There should be one to four full hair follicles in the unit and one or two fine hairs as well. There are sebaceous glands in the follicular unit which produce oil. 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. They waste no time, though, because the small grafts are vulnerable when their follicles are outside of the skin. The goal is to get the grafts in as quickly as possible while staying true to the design. Next, the doctor looks over the hair transplant for quality control. He may take a good deal of time tweaking the placement of grafts before he is satisfied that they are all set properly into their receptor sites in a pleasing fashion. You might wonder, if that is the case, why more women do not have hair transplant surgery. You may be surprised to know that many women are not good candidates. Women usually have a different type of hair loss than men. Male pattern baldness uncovers parts of the top of the head. However, the sides and back of the head are usually covered with healthy balding-resistant hair follicles. It is not unusual for itching to occur on areas affected by hair transplant surgery. Yet, it should not last more than a few days. If you use shampoo and wash the hair every day, it helps with the problem. 5. Swelling. Almost everyone who has hair transplant surgery has swelling in the forehead and around the eyes. Hair cloning is done by taking stem cells, or dermal papilla cell, and cloning them in a laboratory setting. They are then multiplied and combined. The end result is an increase in the number of hairs available for hair transplant. Not only is hair cloning possible, it has been proven in many scientific studies. You should figure that the average number of hair transplant grafts needed to cover a balding area is 25% of the original hair that was there. 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.
