Of course, to follow the dental analogy, after the numbing wears off there is plenty of pain where the tooth was before. With hair transplant surgery, there is pain after the surgery as well. Swelling is normal after hair transplant surgery and can even keep you away from work. Your skull may feel very unusual for weeks. 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. To understand how follicular units have affected hair transplant surgery practices, it is necessary to first understand what a follicular unit is. A follicular unit is a single entity that is made up of several parts. All these parts are necessary to the whole. The first part, and the one most people getting hair transplant surgery are interested in, is the hairs. 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. This includes taking out hair plugs from past hair transplant procedures gone wrong. The price may be around $12 per graft when other grafts are being put in at the same time. If the plugs are just being removed, the price is higher, about $15 per graft. Scar revision surgery is usually done at a flat fee, perhaps around $1000 for the procedure. The strip of scalp will be about an inch wide and five inches long. Then, the hair transplant doctor pulls the skin together where this was taken out, and stitches it together. Finally, the micro grafts will be finished by being divided into individual grafts by using a stereomicroscope. The surgical team will make a variety of grafts from eight-shaft mini grafts to one or two shaft micro grafts.
