I recall how devastated I was when my hair was falling out. There was hair all over the place...bed, car, home, etc. I do hope you will research the different kinds of thyroid hormones available. If you are hypothyroid and have been placed on meds, I'm sure you need medication. Some meds have both the T4 and T3 in them. Some doctors believe that certain folks need to take both. But, if you still have symptoms of low thyroid (which would include hair loss), than it might very well be something to explore. For me, vitamins and the proper thryoid medication did the trick. I also really got "into" a healthy way of living including eating properly and exercise. But my "gut" tells me it was the right thyroid hormone and vitamins that really did the trick. Knock on wood, lighting a candle, crossing myself, thanking my higher power and doctor, I have a full head of shiney, hair today.
