In brief: Maybe ;)
The thyroid hormone medicine should not affect your hair directly.
However, if your dosage is low, it can indeed affect your hair, as well as cause many other symptoms. If you are having such a problem, some lab tests with your primary doctor should help identify the problem. If you are taking thyroid hormone, you should have your levels checked at least yearly.

Typically the condition of low thyroid hormone is associated with weak hair. The medicine should help to reverse it.

In brief: Thyroid dysfunction
Weak and brittle hair is one of the hallmark signs of thyroid dysfunction.
Accurate evaluation of the current thyroid regimen is necessary if a patient is experiencing more symptoms.
