Current status of hair restoration surgery

Hair restoration has emerged as a subspecialty of aesthetic plastic surgery practiced by a wide range of doctors including plastic surgeons, general surgeons, dermatologists, and even general practitioners. As a current trend, most doctors practice "Ultrarefined follicular unit hair transplantation" in which the entire procedure is done precisely with minimal donor scar. In selected cases, Mega or even Giga sessions are now done with natural appearance and almost undetectable scar, in a single session with good density. This article is an attempt to review the history of hair restoration surgery, describe a novel technique currently practiced in our center, and summarize possible future innovations.
