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. This is so that the donor site scar will be adequately covered up until the sutures heal. Then, your doctor will schedule other check-ups, which you should also attend. At first it may seem as if you have to be very careful with your hair - and you do! It does not make sense to spend hundreds or thousands of dollars having your hair transplant surgery and then not follow through with good care. You do not need a person whose only agenda is to sell you on getting hair transplant procedures done. 3. You should start to get concerned if your doctor has no specific good stories to tell about hair transplant surgery they have done. You need to see before and after photos. You need a way to contact former patients. 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. It is just your scalp after all, not muscle or bone. 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. Why Some People Do Not Want To Have Hair Transplant Surgery Hair transplant surgery is not for everyone. In fact, some people have been so disappointed and even angered about their results that they have filed class action lawsuits against hair transplant surgeons and clinics. There are several reasons they give for their dissatisfaction.
