Does Finasteride Work?

In clinical studies, improvements in hair growth have been seen as early as 3 months with finasteride 1mg. Researchers concluded that after one year of treatment, 66% of men treated with finasteride had increased hair growth, and 80% of men after two years.

These benefits were seen up to 5 years later, with a significant increase in scalp hair count and hair regrowth.

One study found that “1 mg/day promotes hair growth and prevents further hair loss in a significant proportion of men with male pattern hair loss.”
