Mega-sessions in which large numbers of grafts are completed at one time are cheaper per graft. Figured into the fee is the use of highly skilled technicians to help the doctor. Repair work is also done at a per graft price. This includes taking out hair plugs from past hair transplant procedures gone wrong. The cysts do not usually last more than a few weeks and are rarely more than the size of small pimples. 10. Scarring. If you have keloid scarring after hair transplant surgery, it is probably because you are genetically inclined to have it. Very infrequently, patients have scarring that takes the form of ridges. The doctor will explore both the hair loss you have suffered, and the hair growth you still have. This is very important, because knowing where the donor hair for the hair transplant will come from is imperative. The doctor will also want to know the patterns of baldness and hair growth in your family history. For example, if a man has a particularly hairy chest, some hair can be used from that area as donor hair for the head. This hair transplant procedure requires a surgeon skilled in the latest techniques in order to keep scarring to a minimum. Another aspect of choosing donor sites is the color of the hair being used in the hair transplant. 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. It does not hurt one bit go into the process with an idea of your own about how the treatment should go. Contacting professional organizations is also a good idea. Once you have found a doctor or doctors to consider, make sure they let you see examples of their work. It will not be enough to see what they can do with a virgin scalp. You need to see how successful they have been in dealing with problems such as the ones you have.
