Recently I was diagnosed with a minor hypothyroid. I had pretty moderate hair loss and was am now on syntrhoid. Ever since I started taking synthroid I have noticed a major increase in dandruff. I noticed that when the skin falls the hair has been falling out with the skin. I was wonderng if this is normal with syntrhoid or if it is a different hormonal imbalance that is causing it. I had my TSH tested recently and my number is now within the normal range thanks to synthroid, but my hair is having serious problems. What should I do?
