Re: Question About Hair Loss on Synthroid
People tend to have hair loss when there is a change in hormone levels. In your case, you can be losing because you have changed the thyroid hormone levels.
However, if this turns out to be an insufficient dose (too low or too high), you could continue lose hair until you find the right dose, and then regulate on it. Once you get to the right dose, and regulate, the hairloss should hopefully stop, and the good news is, it should grow back too.
