They also use a double layer closure method to help the skin heal properly. As long as the surgeon knows what she is doing, the scars are a minor consideration. Another aspect of scarring is when doctors go in for multiple hair transplant surgeries. A new strip of donor tissue has to be taken each time to supply the grafts for the new transplant. Yet, if you use your imagination, you can see how the right style would make the hair transplant look great. Before you go in for your hair transplant surgery, your surgeon will give you some facts about how to care for your hair before the surgery and after. He will emphasize that the hair on your crown should be at least 2cm long. How to Take Care after Hair Transplant Surgery Once you have made the decision to have hair transplant surgery, you are probably jumping ahead to thinking about your post-op plans. You most likely cannot wait to see the faces on your friends and acquaintances when they notice your new full head of hair. 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 is one reason why you should ask a lot of questions when you look for a hair transplant surgeon. Up-to-date techniques for hair transplant use only the follicular unit and not a large amount of surrounding tissue for the donor grafts. This cuts down considerably on the amount of pain experienced. They may have little or no experience. This is just a way to get names that you can check out. When you contact a hair restoration surgeon, ask to see a portfolio of patients' photos before and after hair transplant surgery. You should be suspicious if you are shown less than a dozen or so sets of pictures.
