Except in one small way. One manufacturer has developed a product that really works (although, truth be told, it was an accidental discovery). Propecia has been through all the clinical trials and now carries the full approval of the Food & Drug Administration. In every post-marketing survey carried out, men confirm the initial tests. It really does work. So, despite all the claims and promises made by the "rest" of the products, none of which have ever been through full clinical trials - one other drug with FDA approval lists hair growth as an undesirable side effect and its use to stop hair loss does not have FDA approval (it can also be fatal to your pets). So Propecia is the best (and kind to your pets). Ignore all the marketing slogans for the magic products. They did not work in Ancient Rome. They do not work now.
