Could be part of it. Minoxdil is just one kind of vasodilator. There hasn't been regrowth noticed with other classes like ACE inhibitors. And in general cardio training hasn't been shown to improve hair loss. Minoxidil might induce vascular endothelial growth factor as well. Maybe you need both? It also seems to work much better in combination with finasteride or dutasteride. All medicine is a little human experimentation. We don't even understand the complete mechanism of action of acetaminophen and that drug has been around for over 130 years. Generally if something works, we're happy.
