Dr. Unger was one of the investigators in the early clinical trials on the treatment of male pattern baldness with topical Minoxidil (Rogaine) for the Upjohn Company and oral finasteride (Propecia) for Merck Research Laboratories.

He is currently a medical advisor to Restoration Robotics, a California research company that is developing a robotic arm that will harvest and move naturally occurring groupings of hair (''follicular units'') from one place to another.  If successful, this will eliminate the linear donor area scar that is a by-product of conventional hair transplanting.  It will also improve the production of optimal graft types, as well as graft quality consistency and speed of production.
