What is the role of lasers in transplantation?

Laser hair transplantation was pioneered by Dr. W. Unger and Dr. L David. Up to this point many lasers have been tested but none of the present generation of lasers has been found to give a consistently superior result over traditional methods. I addition there is usually more postoperative crusting and a longer delay before transplanted hairs begin to grow. At this point lasers for use in hair restoration, are in my opinion used, by some, as more of a marketing tool, than a clear cut scientific advance.
