Hi Donnie 317. You mention that on Synthroid and Cytomel that you are in "normal ranges". Where in the normal ranges??? Do you know where your freeT3 and free T4 are? For some people, hair loss doesn't stop until you get those ranges in the upper end. And neither does the problem with weight. It appears you have to have both the T3 and T4 up there to get results!
Also, female hormones can come into play. My hair was still falling out when my fT3 was very high and optimal. I now realize it's because I have been on synthetic female hormones. I have recently made a switch to using compounded natural estrogen and progesterone, and I am fairly sure it will be the final step in stopping the hair loss.
