Is propecia/proscar effective in stopping balding and hair loss?

Yes: Propecia (finasteride) has been clinically proven to help. In a 5-year study of men with mild to moderate hair loss, 2 out of 3 of the men who took 1 mg of Finasteride daily regrew some hair. However, Propecia (finasteride) has been linked to long term erectile dysfunction. Other treatments exist such as hair transplantation.
