When should I start Propecia (Finasteride)?
Five years of clinical data with Propecia (Finasteride) show the sooner, the better. If you have male pattern hair loss, the sooner you get started on Propecia (Finasteride), the more hair you may have later. In fact, in the longest reported controlled study of male pattern hair loss ever conducted, men who were started on a placebo (sugar pill) and then placed on Propecia (Finasteride) 1 year later never caught up to the men who were on Propecia (Finasteride) for the full 5 years.
