Hello, welcome to HCM, I am Dr Das
Firstly, hushimotos thyroiditis
is an autoimmune condition where destruction of the thyroid tissue occurs due to presence of anti TPO antibodies
Normal TSH level depends upon the test method and the laboratory. But cut off value taken is 7 to 8 not more than that.
Continue the treatment. When the TSH level
comes down to normal, then the hair fall
will automatically decreases.
