No one knows how exactly minoxidil works, but it’s generally accepted it has to do with vasilodation methinks. Any oral vasilodator is gonna f*** with your BP and heart to some extent. I’m not sure any commercially available topical vasilodators exist, but some guys have reported success with a homemade topical sildenafil concoction
Side note: I’ve noticed a disproportionate amount of Indian dudes on hair loss forums. Is male pattern baldness more prevelant in Indians or are they simply more motivated to beat it?
