I have read alot on this and was wondering just how large an effect can problems with ones thyroid have. I have been taking kelp just to try and ensure that underactivity of the thyroid does not affect me, however i have read recently that overactivity can be just as detrimental to hairloss. Is this true? And what are the symptoms of under/overactivity of the thyroid? Is the only reliable way to determine for sure if it is a problem is to go to the doctor for tests?
Thanks
