I'm hypo and I'm being treated by Dr P for Adrenal Exhaustion. I've always had thin, fine hair which got worse as I became more hypo. However since taking thyroxine it started to get curly (not in a good way). Although I should have gone grey years ago, I haven't but my dark hair colour was getting lighter. This has suddenly changed and now its getting darker again - either the Adrenal Extract or the Thyroid Extract I was prescribed I'm thinking. It should have got lighter from the sun. Has this sort of thing happened to anyone else?
