Hey everyone, just recently started applying RU and have been having decent success with it so far. Far less hair shed in the shower and when I run my hands through my hair. Also noticed a few new black hairs on my hairline popping out. Recently however I stumbled on a post claiming that Ru can cause irreversible heart damage? Was just wondering if there was any validity to this claim cause it has done its job of scaring me into dropping Ru despite my current success.
