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. Most hair transplant surgeries today involve micro grafting to some degree. Micro grafts hold about three or four hair follicles. Older style hair grafts often held more like a dozen hair roots. These new micro grafts are only possible because skilled surgeons have refined the methods of extracting them. It may take special post-operative care and longer down-time. Ask your doctor if she expects you to have more than one surgery session. You may need to have the plugs removed in one session and allow that to heal before going on to the next phase. Your doctor may not know the answer to this until after she sees how your first surgery has gone. Your relatives may have had hair that went bald into a horseshoe pattern and held at that stage. If this is the case, your surgeon will know what to expect. Then, he can take "bald-proof" hair from the sides and back of your head as donor hair and perform the hair transplant. If you have lost your hair because of some kind of trauma or burns, you will also make a good candidate for hair transplant surgery. Excessive drinking may be a problem due to anesthesia and medications you have to take in the course of having your hair transplant done, so you may be asked to refrain from drinking until your head has healed. You may even be told whether or not to take certain vitamins and medications. The doctor will discuss where your hair transplant procedure will take place.
