Certain types of auto-immune diseases, such as alopecia areata can now be treated by means of hair transplant techniques by using the donor strip method. Yet, in the future, hair cloning will make hair transplant easier for these people who often have very little hair to use for grafts. 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. Because the eyebrow hair is made of individual hairs, hair transplant surgery must involve creating those single units of hair. To do this, hair is taken from the scalp, just as in other hair transplant procedures. Then, the follicular units are divided into individual hair grafts. This is done with a stereomicroscope. This method keeps the units intact and ready to transplant. Earlier methods such as mini-grafting and micro-grafting broke up the follicular units. As a part of the hair transplant process with Follicular Unit Transplantation (FUT), a new microscope technique was used. It is called stereomicroscopic dissection. The direction the hair grows, both on the front of the head and at the crown, are very important, too. The doctor must make the condition of the newly placed hair look like the patient's own natural scalp hair. The angle that the hair is put in determines how much it will stand up from the head. 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. 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. People who have this kind of problem need special treatment. If a patient is known to suffer from keloid scarring, the first thing a reputable doctor will do before hair transplant surgery is to explain the possibility of unsightly scars. This requires a very honest surgeon, since the patient may decide the procedure is not worth the scarring it will cause.
