Good day.
Have you checked your thyroid function recently? It is good to check CBC ( to look for iron deficiency clues), Vitamin B12 levels etc along with a TFT. stress,Vitamin and iron deficiencies are other causes of hair fall.
To answer your question regarding the adequacy of dose, you need to provide a recent thyroid function test ( TFT) and based on that we can decide if the dose you are taking now is adequate/excess or less. Just a dose change will not cause hair fall provided the TFT is in normal range.
