However, if the surgeries are handled in the proper manner, the scars are barely noticeable. They are thin to the point that they can barely be seen in most cases. Skilled doctors have ways of making the scars practically disappear. First of all, the surgeon must be very skilled in choosing the site of the path where he harvests the donor tissue for the hair transplant. The first part, and the one most people getting hair transplant surgery are interested in, is the hairs. 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. Then, he can take "bald-proof" hair from the sides and back of your head as donor hair and perform the hair transplant. If you have lost your hair because of some kind of trauma or burns, you will also make a good candidate for hair transplant surgery. This is because the hair you still have will probably still be healthy. Surgeons usually do give some sort of estimate of the cost of the entire procedure of a hair transplant. A reputable surgeon will emphasize that it is only an estimate and that things may change once the procedures are started. Also, she will give an honest accounting of what she expects the procedure to cost. Excessive drinking may be a problem due to anesthesia and medications you have to take in the course of having your hair transplant done, so you may be asked to refrain from drinking until your head has healed. You may even be told whether or not to take certain vitamins and medications. The doctor will discuss where your hair transplant procedure will take place. Some people believe that hair transplant grafts using cloned hair would be about the same cost as the usual hair transplants that are available today. Other experts believe that the price will be much higher - perhaps three or four times per graft higher - because of the specialized methods required to do the work.
