If you protect the skin on your scalp after getting a scalp hair transplant, you will help the wounds heal much faster. You can start out by getting some kind of hat. It does not matter what kind of hat it is, as long as it is fairly loose-fitting so that it does not rub on your new hair transplant grafts. Many doctors will refuse to do immediate hair transplants if they are put to the test. There are advantages to getting hair transplant surgery under the age of 25. Most of these patients are healthy. They do not usually take medications. They are often optimistic and have the motivation required to make the commitment needed for what may end up being lifelong treatment. It hides the sutures and eventually hides any scars you might have. You will be told to use your normal shampoo before the hair transplant surgery. No special scalp treatment will be needed. Do not worry about any scraggly hair on top of your head. The doctor will blend it in with the grafts as he goes. This includes taking out hair plugs from past hair transplant procedures gone wrong. The price may be around $12 per graft when other grafts are being put in at the same time. If the plugs are just being removed, the price is higher, about $15 per graft. Scar revision surgery is usually done at a flat fee, perhaps around $1000 for the procedure. Then, the follicular units are divided into individual hair grafts. This is done with a stereomicroscope. Inserting these micro-grafts is a very tricky business. Creating the correct angles is difficult. If the patient does not have straight hair, her curly hair must be inserted by rotating it so that it lies even with the curve of the brow that is being made. 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.
