It should have an SPF of at least 30. Having just the right amount of blood flow to the hair transplant sites will make a big difference in how fast they heal. For example, you need to make sure you get enough blood flow during the night. You can do this by sleeping on pillows to elevate your head. Your usual pillows can be used, or you can buy wedge-shaped pillows made for this purpose. 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. You are not asking too much - it is a major commitment you are making. 4. If your doctor says to try a few hair transplant grafts and then decide, run. This is never a good idea. Once you start having the grafts done, you are committing to a full set of procedures. Otherwise, your hair will end up looking out of balance. This hair can be used as donor hair to replace hair you have lost on your balding spots. If your hair in these areas is not healthy, you face a difficult problem - where does the surgeon get the hair? A new procedure allows doctors to use donor hair from other parts of the body. For example, if a man has a particularly hairy chest, some hair can be used from that area as donor hair for the head. It is called stereomicroscopic dissection. This means that the follicular units are carefully taken out of the donor tissue and kept individually intact. When doctors use hair transplant procedures with FUT, they do not have to use quite as large of a donor site. The follicular units are small and they can be separated from tissue that has no hair, under the microscope. It is a common circumstance to have the mini grafts in the central and crown of the scalp and micro grafts at the hairline and around the edges. If a person had this arrangement after a hair transplant and then shaved the micro grafts, the mini grafts would look decidedly unnatural. However, with the micro grafts on the leading edges, they blend in and give the hair fullness.
