It had gotten thicker and healthier since I started eating primal in April but over the last two months it has started falling out and just looks thin and unhealthy. Figures the only part of my body I don't want thin is the one that goes. My doctor has lowered my thyroid meds three times since April, the last time about a month ago. I changed shampoos about two months ago as well. Any other thoughts? This is driving me nuts!
