There are several reasons they give for their dissatisfaction. 1. Underestimating Procedures. Certain surgeons and clinics underestimate the number of procedures necessary to achieve the desired effect. This leads people to have a false hope of having a full head of hair in a very short time. When this does not happen, they are understandably angry. Facial hair grafts for those who have lost eyebrows or eyelashes are also high, at $11 to $15. These are specialized procedures. Follicular Unit Extraction hair transplant costs more than micro-grafts. FUE may cost as much as $15 per graft. Mega-sessions in which large numbers of grafts are completed at one time are cheaper per graft. You may be given specific guidelines for eating in the weeks leading up to the 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 need to let the plug sites heal as well as the new insertion sites and possible new donor sites. 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. That is because a naturally-occurring enzyme in the body combines with testosterone to create a chemical called DHT. This chemical is responsible for the hair loss on the tops of men's heads when they have male pattern baldness. However, it does not affect the back and sides of their hair in most cases. Another important factor for hair transplant is the color of the hair in contrast to the color of the skin. For a light-skinned man with light-colored hair, or a dark-skinned man with dark colored hair, it takes a certain amount of hair to cover the baldness. However, a light-skinned man with very dark hair will need much more hair to provide the same amount of coverage.
