Hi everyone, I am new to the site and am hoping that someone can help me understand what is going on with my hair. I have been losing my hair for over 7 years. 2 months ago when I was prescribed 30 mg of Armour Thyroid eventhough my TSH was in the normal range (4.7). I had many symptoms of hypothyroid but up until now, the doctors wouldn't treat me as hypothyroid because I was still in the "normal" range. I felt better physically almost immediately. However, after 3 weeks on Armour Thyroid I began to experience extreme hair shedding. 300 to 500 hairs a day. My hair has been falling out in clumps and falls out continuously all day. I switched to 15 mgs last week but the shedding continues. It is frightening. Has anyone else had this happen? Should I stay on the Armour and hope my hairloss slows down or get off the Armour immediately? I am so depressed.
