How long does it take before individuals start to notice the benefits of Propecia?
Hair naturally grows at a rate of about a half an inch per month, so it may take up to sixth months for the effects of Propecia to be visible. However, most men begin to see some results early in the first three months. These results include a decrease in the amount of hair loss, general improvement in the condition of the hair with noticeable re-growth occurring after sixth months.
