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. Planning for the procedure is necessary before you even make the final decision to have it done. Once that step is completed, you will be ready to start the preparations for your surgery. Before you are approved for a hair transplant procedure, the doctor will have to sign off on you. You must be deemed appropriate for the surgery. Based on the fact that the average Caucasian male has a density of 2 hairs per millimeter, it can be assumed that the average density of hair is 1250 hairs per square inch. Figuring at an average of 2 hairs per follicular unit, it would take 625 follicular units per square inch. To get 25% of that, you would need 156 follicular units per square inch. 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. The next step with such a patient would be to discuss ways the keloid could be covered. A doctor who has done many successful hair transplant procedures will have a list of people willing to talk about their experience. You can call each one and ask about how the procedure went for them. Be aware that not all hair transplant doctors are scrupulous businesspeople. Many will try to fool you into believing they are more experienced than they are. This is important because smoking makes you heal slower by inhibiting blood from flowing to your skin. It may be hard to do, but if you quit smoking just for the surgery, it might not be so hard. Then, once you have done that, you may find that you want to stay off the cigarettes or cigars even after the hair transplant have healed.
