Then, the follicular units are divided into individual hair grafts. This is done with a stereomicroscope. Inserting these micro-grafts is a very tricky business. Creating the correct angles is difficult. If the patient does not have straight hair, her curly hair must be inserted by rotating it so that it lies even with the curve of the brow that is being made. The temperature must be ideal or the small grafts will not survive the procedure. This is done very carefully in order to ensure a good result. The surgeon will make tiny incisions into the scalp where the hair transplant grafts are to go. These are called the receptor sites. They are made with a very thin surgical needle. It was during this decade that doctors had begun to try moving balding-proof hair follicles to the balding areas of patients' heads. They used hair from the fringe, or back and sides of the head, to accomplish this. The doctors were trying to determine whether hair follicles were balding resistant because of where they were located on the head or because of something inherent in the follicles themselves. 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. 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 normal hair transplant procedure will cost differently depending on the number of grafts even though the cost per graft goes down the more grafts you have. However, there are some minor complications or side effects that sometimes come with the surgery. 1. Thinning. If you have hair transplant surgery, you might be alarmed if you notice that the hair you already did have is getting thinner. This is a normal post-operative condition. The thickness comes back within a few months after surgery.
