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. 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. Previously, when hair plugs were used, doctors did the hair transplant surgeries much differently. They used an instrument called a trephine to cut circular grafts from 2mm to 5mm in diameter. These plugs were inserted into the balding area. Now, a multi-bladed knife can be used to cut long thin strips of donor tissue. Once the surgeon has made all the hair transplant incisions that lay out the design he has created, the specially trained surgical team steps in. They use his plan to accomplish his goals, and in turn the goals of the patient. The groundwork is done for them by the surgeon when he does his incisions. If the surgeon he sees is not in that ballpark, it may be wiser to look for another surgeon. If however, the surgeon estimates a similar number, just make sure all the grafts go onto the balding parts of your scalp. To calculate the number of grafts you need for hair transplant surgery, there are several factors to take into account. Hair transplant surgery will not correct this problem. It is best used to move hair from one place to another. There is a very small percentage - about 5% of all women with baldness problems - who are good candidates for hair transplant surgery. The thing that all these women have in common is that they all have healthy areas of hair follicles that can be used as donor sites.
