I am obviously not Shenacat, but I wanted to reply.
How were you feeling when you were on the Armour? Is the thinning hair new or worse since starting Levoxyl?
With Hashi's, the goal is to be on enough thyroid replacement that your body's natural production of thyroid hormone is completely suppressed so you can avoid the hyper/hypo swings (this is called block and replace, I believe). I doubt 1 1/4 grain of Armour was enough to do that for you, and your labs back that theory up. Many people need to be on at least 3 grains, with their TSH suppressed to under 1.0 and FT3 and FT4 towards the top of the range, to feel 'good'. It looks like your doctor drew total T3, not free T3, so it's hard to get a good picture of what your thyroid is doing.
