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. 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. 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. It might make a difference in the angle of the hair or the direction of the hair. The doctor will show you before and after pictures of his past hair transplant patients. Do not be discouraged if they all seem to have the same plain haircut in the after pictures. This is often the case when the doctor is trying to be truthful. If you do not have enough hair, you cannot have a normal hair transplant surgery. However, there are other surgeries that can be used in conjunction with hair transplant to achieve similar results. The difference is that these procedures are generally more painful. 6. The grafts may not survive. Few surgeons will divulge to you the fact that hair grafts do not always survive after hair transplant surgery. 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. For example, 100 grafts may cost you $1500, while 3000 grafts may cost about $12,000. The grafts will be more permanently set into place when the technicians dry them by blowing a cool blow dryer across them. This makes them adhere in their place so that no bandages are necessary. The patient will be asked to bring, or will be given, a baseball cap for the ride home from the hair transplant procedure.
