A member asked:

Does hair color negatively affect hair loss/ hair thinning due to underactive thyroid?

A doctor has provided 1 answer

No.: If you mean hair dye, no -- it will make no difference, one way or the other, in your rate of hair loss. The hair will usually grow back once your thyroid level is corrected, however.
