hmm i have heard of hairloss due to scalp hyperhidrosis (excessive sweating) which would be cured by a botox
and i could imagine that a botox to the scalp would impove bloodflow so it would work similar to minoxidil
but the thing is, A- that is the sun, not a brilliant source and B- people who have chemo regrow hair normally after anyway so how can we prove the botox had any improvement
on the other hand i would love for it to work and i could have a regimen of 6 monthly botox lol (and it would cure my annoying sweaty scalp lol)
also i wonder how this is only been discovered NOW when we have been botoxing sweaty scalps for a while
