When doctors do hair transplant surgery to replace eyebrows, they have to make sure that they put the hairs in so that they will point in the natural hair direction. For this, the surgeons use very fine gauge needles. They must also use this to help the hair to lie flat. Because the eyebrow hair is made of individual hairs, hair transplant surgery must involve creating those single units of hair. 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. Another important factor for hair transplant is the color of the hair in contrast to the color of the skin. For a light-skinned man with light-colored hair, or a dark-skinned man with dark colored hair, it takes a certain amount of hair to cover the baldness. However, a light-skinned man with very dark hair will need much more hair to provide the same amount of coverage. It is just a fact of life. 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 surgery will make the skin especially sensitive. 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. The truth is that you have many small wounds and you need to protect them. 4. Hair transplant can be a time-consuming commitment. Treatment can often last one to two years. Mega-sessions where thousands of grafts are done in one sitting help to shorten the overall time. However, the length of these sessions is often grueling.
