What clinical studies have been done concerning Propecia?
Clinical studies were conducted in men age 18 to 41 with mild to moderate degrees of male pattern hair loss. All individuals treated with Propecia received a tar based shampoo (Neutrogena T/Gel shampoo) and were instructed to wash their hair at least once per day. Clinical improvements were seen as early as three months into the treatment with Propecia. In men with vertex hair loss, global photographs revealed hair re-growth in 66 percent of men. Furthermore, hair counts with these men indicated that 83 percent of the recipients had no further hair loss over the two-year clinical trial period.
