I'm 47 and I definitely can feel hormonal changes (perimenopause) going on in my body. Bloodwork doesn't show much, but it's happening... Last year I noticed a diffuse thinning of my hair. Then it kind of leveled off (maybe). Then, a month ago, I feel like (within a few days) I had a sudden thinning, again. Is this possible? I don't notice any more shedding (I've always been a shedder, but have actually noticed less, lately) than usual. But, I notice my widow's peak growing, and fine, short hairs where longer hairs used to be. If I lift up the top layer of hair on the side of my head, my scalp is right under it. There is not much 'undergrowth' anymore. Are the short, fine hairs 'miniturization'? Can this happen very quickly?? When I pull back my hair into a ponytail, I would say it's 60% of what it was. Maybe that's exaggeration, but it's a lot less. I've been checked by two dermatologists who don't see anything suspicious going on (besides some hair thinning). Bloodwork fairly normal, though some alternative docs would say that my 2.5 Thyroid is a little high. And I was a little low on Vitamin D. Does this sound like Alopecia Areata, and, if so, is there anything to do about it other than Rogaine? I'm really loathe to do that. Kind of freaking out, but depends on the day. Thank you so much for any advice/help!!
