I don't know, to be honest. My hair has thinned, but it's not noticeable - I only know it's thinned because of the amount that comes out when I shower. Receding gums - I have had that going on for a couple of weeks. It's freaked me the hell out, because I'm very fastidious about dental care. I've been using gengigel paste and mouthwash to try and counter the effects, but it hasn't been long enough to tell yet. I don't think this helps you, but it's definitely something I've noticed. Anyone else?
