I lost a lot of hair (more than half) before i got detected with hyperthyroidism. Post detection, i started taking thyronorm 50mcg and my thyroid levels have leveled out. But now, even after two years of continuing the medication, my hair has improved very little, and it is also very dry unlike the soft and silky hair i used to have before. Is there any chance that my hair will grow back to what it was before? and if yes, then how much more time does it need?!
