I'm suspecting I have a thyroid problem. My hair is falling out and ALSO my eyebrows and a few other symptons, it comes and goes. BUT of course I can't know for sure until I get tested, I'm also almost sure I'm low in iron, so it could be that too. But I think the answer to your question is basically yes, it can affect. Although I've had this type of hairloss before taking PM. From what I've been reading a lot about that these last few days, so here's what I found:

"According to the late clinician John R Lee, M.D., estrogen dominance is behind many cases of midlife hypothyroidism, in which there are inadequate levels of thyroid hormone. When estrogen is not properly counterbalanced with progesterone, Dr. Lee surmised, it can block the action of thyroid hormone, so that even when the thyroid is producing normal levels of the hormone, the hormone is rendered ineffective and the symptoms of hypothyroidism appear. In this case, laboratory tests may show normal thyroid hormone levels in a woman’s system, because the thyroid gland itself is not malfunctioning. This problem is compounded when a woman is prescribed supplemental estrogen, which then leads to an even greater imbalance. Prescribing supplemental thyroid hormone in that case will fail to correct the underlying problem: estrogen dominance."
