There are individuals with other specialty training background that do good hair transplant procedures. In general, I think that the plastic surgeon is more likely to be able to use mini grafts, tissue expansion, flap advancement, and scalp reduction techniques to accomplish the patient's goals. I think that having many techniques available increases the likelihood that one can meet the patient's expectations. There is, I think, a never-ending supply of over the counter treatments for baldness. I am not aware of any that have undergone scientific testing to show their effectiveness.
People seek treatment for hair loss to improve their self-esteem.
There are many factors that influence the outcome in our attempt to correct baldness by surgical approaches. It is important to choose your surgeon and to be clear with the surgeon about your goals. It is important for the surgeon to attempt to relate to you the extent to which he or she feels the goal can be met. The recent advances into the mini graft approach have produced much better results than were available in the past with the larger plug hair replacements. Many patients do experience a restoration of self-esteem and confidence following hair replacement therapy.
