Generic propecia - Finasteride

A 5-year clinical study demonstrated the effectiveness of PROPECIA.
9 of 10 men on PROPECIA had visible results (either regrowth of hair, 48% [134 of 279], or no further hair loss, 42% [117 of 279]) vs 25% (4 of 16) on placebo (sugar pill), according to an assessment of photographs by an independent panel of dermatologists.
2 of 3 men who took PROPECIA regrew hair, as measured by hair count. All the men in the study who were not taking PROPECIA lost hair.
A majority of men who took PROPECIA were rated as improved by doctors—77% (210 of 271) vs 15% (2 of 13) with placebo.
A majority of men who took PROPECIA reported their bald spot getting smaller, their hair loss slowing down, and the appearance of their hair improving.

2 of 3 men on PROPECIA regrew hair, as measured by hair count.

Simply put, all men who took the placebo (sugar pill) lost hair by the end of the 5-year study.

On the other hand, most men (2 of 3) on PROPECIA gained hair at the end of the 5-year study.

By the end of the study, there was an average difference of 277 hairs in a test spot (1-inch circle on top of head) between men who took PROPECIA and men who took placebo.

Throughout the 5-year study, the difference between the 2 groups increased. The maximum increase in hair count with PROPECIA occurred in the first 2 years of the study.

9 of 10 patients who took PROPECIA had visible results (maintenance or improvement) according to photographic assessments by an independent panel of dermatologists.

An expert panel of dermatologists determined that 90% (251 of 279) of men who took PROPECIA at 5 years had improvement or no visible hair loss vs 25% (4 out of 16) who took placebo (sugar pill).

Further treatment is unlikely to help if the drug has not worked within 12 months.
