Regrowth of hair loss is often possible. Beginning in 1984, Peter H. Proctor, PhD, MD developed various treatments for hair loss by systematically screening new baldness treatment agents on persons who had previously failed other treatments for hair loss. So far, the US patent office has awarded to Dr. Proctor nine US patents for the treatment of alopecia, hair loss and balding. He has been the subject of articles in various media, including Newsweek, Esquire, and Men’s Health magazines.
