Propecia is an offshoot of another medication called Proscar, which has been widely used since 1992. This 5 mg tablet containing the active ingredient "Finasteride" was used to reduce the adverse effects of DHT on the system. As hair loss is primarily linked to the effects of DHT, it was reasoned that Finasteride would help stop or reverse the process. FDA trials on 1,500 men yielded shocking results. Nearly 83% of men who continued treatment for 2 years either saw a complete stop of hair loss, an increase in hair growth, or
both. Results were confirmed by actual hair counts and nearly 80% of men were
categorized by visual assessments that their appearance had improved.
