Warning to all men who are considering using Propecia to treat their male pattern baldness: it causes sexual dysfunction in nearly all users and this is often PERMANENT! The alternative, Rogaine, is not much better and carries a risk of causing skin problems, dark circles and accelerated aging. Fortunately, there IS a natural (and much safer) alternative.
Please lend your support to Kevin Malley, who is on hunger strike to draw attention to the ravages of Propecia by circulating this story.
