Queen of Chaos had posted a thread in the Health Forum I think about the fact that just a simple tyroid blood test did not always show a problem when there was a problem and that sometimes you have to have an ultrasound or maybe cat scan.
She had found out she was having problems after many years of suffering by further testing.

But I do understand there can be hereditary reasons and stress can effect your hair.

Sorry you are struggling, good to hear you have a good husband that is understanding and kind, worth a hundred friends.
