Does hair color negatively affect hair loss and hair thinning due to underactive thyroid?
2 doctors weighed in across 2 answers
Yes: Hair coloring can negatively affect hair loss and hair thinning. Underactive thyroid can also negatively affect hair loss and hair thinning. So both will even moreso negatively affect hair thinning and loss.

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.
