The types of situations that can cause hair loss include hormonal changes, poor diet and nutritional deficiencies, a variety of medications , surgery, and many medical conditions, but noticeably, thyroid disease.
Many people notice rapid hair loss as a symptom of their hyperthyroidism or hypothyroidism.
If you're experiencing hair loss and are just starting treatment for a hyperthyroid or hypothyroid condition, it's likely that for most of you, the loss will slow down, and eventually stop, once hormone levels are stabilized and in the normal range. This may take a few months, however. But rest assured, I've had many thousands of emails from people, and have yet to hear from anyone who lost all his or her hair, or became bald, due to thyroid disease. In my case, I'd guess I lost almost half my hair. I had long, thick hair, and it got much thinner at various times.
