i must say, yes hair loss has happened to me. and i have hashimoto's thyroiditis. my ranges are pretty high. and i've noticed that i'm experiencing alot of hairloss. pretty depressing and stressing. i don't know what to do myself. i am not completely bald. but there is quite alot of strands that do come out. i am not on synthroid and heard that causes some hair loss as well. so double whammy right there. i just pray for some sort of recovery for all of us on this board. g'luck.
