lavenderbrat, it's actually good you noticed the hair thing. For one thing it's a warning about thyroid so you can get on thyroid meds if you need them. Also you can help your hair. Selenium and biotin supplements can help and a shampoo called Nioxin for thinning hair if that's also going on can also make a huge difference. I didn't notice the hair thing until it had gone on long enough that I had a lot of icky brittle hair with some balding spots and it took a long time to fix.
