The efficacy of Botox for offsetting hair loss is not yet well-established by large-scale clinical studies.

“The efficacy of Botox for offsetting hair loss is not clear. There aren't a lot of large- scale clinical studies on this just yet, but it does seem to be at least one reasonably safe alternative to things like Minoxidil, although I think if one were to just want to increase blood flow to the scalp, things like low- dose Tadalafil, which doesn't seem to carry any of the side effects that Minoxidil can carry, we talked about those side effects earlier, that would probably be the better alternative.”
