I still think I have Androgenetic Alopecia, because I do find what look like miniaturized hairs (short, very fine, unpigmented). Also my most affected area is the top of my head. That being said, I do feel like I have general thinning all over my head, and I don't find any miniaturized hairs either in the back or sides, where my hair also feels thinner (I've always had thin hair though, so maybe I'd never paid attention to how thin it really is). To add to confusion, though, now I read this: Source: http://www.hairsite2.com/library/article194.htm I don't know how legit or reliable that site is, but it still got me thinking. I don't know if I could have an iron deficiency (or any other nutrient for that matter)... I mean, I have dry skin, I feel lethargic, my nails are brittle and thin (but only from time to time, at times the seem to get better), I have low sex drive... I never thought those symptoms could be linked to iron deficiency, but I don't know, it sounds more like thyroid problems but my thyroid is supposed to be fine! (I did read that an iron deficiency can mess with some thyroid hormones, though, but I'm no doctor) I also have insulin resistance, without PCOS (at least that's what the doctor said). Maybe I'm just overthinking this and it's simply genetic, though for both of my parents their hair loss started at least after they turned 40 (and I'd said my mom's started later, with menopause). I'm 24... my sister also has this problem, though (she's 25). So maybe we just got awful genes, but I digress. Any thoughts on this?
