This may be due to change in thyroid hormone status and stress.
Would likely give it some more time and get through the radioactive iodine (which I assume is why you are on cytomel) but talk with your doctor about this.
Thank you for response just completed 153 millicuries of my isotope, finally one hot chick this week and to be back on levothyroid today hopefully now once back on hormone will see less hair loss and scalp improvements. I will wait it out and hope for improvement after a few weeks.
