Any supplements to grow eyebrow hair?

Possibly hypothyroid. Thinning eyebrow hair, especially on the side towards your ears, is a classic sign of hypothyroidism. I advise getting a thorough thyroid evaluation- a T4 and TSH is not enough! see http://bit.Ly/1cjnybx a holistic doc is more likely to do a proper evaluation- see http://bit.Ly/19pettq.
