Hair loss is very common - in thyroid patients and non-thyroid patients.
Changes in thyroid medications can cause temporary hair changes.
from what i've been reading on the internet -- hair loss is one of the syptoms of being on synthroid or cytomel.
good luck -- hopefully dr lupo will post here for you.
I am using 1/2 synthroid and the cytomel and my skin and hair seem better again. Thankyou for your answer.
This question I posted about the use of Cytomel breaking off my hair was for Hypothyroid not hyperthyroid. I had no symptoms of Hypo but was told I needed medication. Anyway I did not get an answer to my question I posted 10/20/11
