Hi align. Staying on top of what your full thyroid panel is (TSH, free T3, free T4, TPO), your symptoms vs which meds is critical in feeling your best (see my post on this topic). Hopefully your doctor might be competent with thyroid management and is listening to you as a person and patient. You might have access to your labs on line. Mine are and they go back to mid 2000's, so I can compare. You can call your doctors office at any time to get copies of all your labs, ultra sounds, radiology/biopsy reports, and also obtain a CD of your imaging.
Until you have stabilized on a med, most people have full thyroid tests conducted every 6-8 weeks. Just TSH will not cut it. Full panel is needed to know if you are properly converting T3/T4, and where your antibodies are. Your T3 or T4 might be too low and be contributing to hair loss.
Synthroid and Tirosint are both Levothyroxine, which is only T4, just different brand names. I am on generic Levothyroxine. Some people do better on one versus the other. I think there might also be some allergy issues with one for some people. Everyone is so different.
Armour is natural dedicated thyroid T3 and T4, so totally different than Levothyroxine.
If your current Endo is not providing explanation for hair loss, perhaps consider a second opinion with one who understands T3 and T4 conversation. I personally have only met with two endos, both only once, and that was plenty. One told me she would not have tested my TPO, that I shouldn't be on meds, wasn't sure if I had Hashimotos and had no idea why I was fatigued. (See my other thread on how insanely high my thyroid levels currently are, thanks to me believing her, and a few other doctors). The latest one last week said my low body temp didn't have anything to do with my thyroid and that nodules, once biopsied, don't grow. I feel sorry for their patients who actually believe in what they say.
People need to be their own advocates and understand their health issues, since some doctors don't. I, and a lot of other folks, have found that most naturopaths understand thyroid hormones better than other doctors. They treat whole person, not just the symptoms.
The other thing I wanted to mention is proper absorption of thyroid medication. You must take it on at least a 4 hours fasted, totally empty stomach, water is ok but nothing else, and also wait at least half an hour before eating, if not an hour. Best if waiting an hour to assure no absorption issues. Coffee interferes with absorption of thyroid meds, as do many vitamins and other medications. If you are not following this protocol, that could be contributing to malabsorption and subsequent hair loss.
When you get your lab results, make a new thread here if you need help understanding what they mean. There are very helpful people here who understand the conversion better than I do who can help you.
