Looks like the pfs foundation started a very thorough petition to ban fina/propecia in the US for classical hairloss. https://www.regulations.gov/docket?D=FDA-2017-P-5787 There's a 120 page document stating why and backed by a lot of solid science: https://www.regulations.gov/document?D=FDA-2017-P-5787-0001 Imo, I would not ban it. Even after my experience with the drug I find people need to be free to choose whatever meds they want to take but one has to be aware about all the side effects and risks involved. Sadly most of the time this is downplayed or sometimes people have no clue about the risks. Full disclosure is needed and more studies by non biased third parties need to be conducted since the official Merck studies are not to be trusted.
