Could you abnormal thyroid be that is a little on the high side? I had two friends with thyroid problems, one hypothyroid and one hyperthyroid. Both had problems with their hair thinning. The one with the hyperthyroid was not significantly under weight.
Good luck, I remember how stressful my hair thinning was.
