Hi all, I've been a member of this site for quite a number of years. I'd been experiencing thinning hair for at least a decade which forced me to go into a topper in 2006. Well I finally found what at least part of the cause was in my case. It's hard to believe after all the strife and wearing of a topper for consecutive years, but approximately 9 months ago, I noticed renewed hair growth and less of a need to wear the topper. I was stunned! I had already given up on ever finding an answer - I thought I'd be in toppers/wigs for life. But in summer of 2011 I got to finally return to a hair salon, get my hair dyed and be told that I did not appear to have thin hair anymore. So what do I find the cause to be? Well I had been eating alot of gluten-free foods and avoiding lactose because I was experiencing gastrointestinal problems. I was drinking coffee each day and adding not milk, but soy milk. Can you guess what I was ODing on? It was soy. I hadn't thought anything of consuming soy. It was touted as healthy by the USDA and it's supposed to help hair right? WRONG! Thankfully I kicked my coffee habit at the beginning of 2011. My consumption of soy dropped off quite dramatically. By the summer of 2011 my hair was rallying again and growing. I also witnessed an improvement in my thyroid tests. I was by no means hypothyroid - my TSH had always been below 2.0. However, my T4 had gone to the low side of normal range. Well it improved in 2011. Better thyroid function. If you are experiencing hair loss, I strongly encourage you to cut out soy in every form you can. Again, I was not hypothyroid at all but what I was eating did appear to affect my thyroid function. Not only that, it was making my pudgy. Cows are fed corn and soy to fatten them up before they are killed. Don't treat yourself to the same diet. If you want to learn more about the downside of soy, do go to Dr. Mercola's site and read up. I so much wish I had years ago when it was emerging that processed soy and soy derivatives are anything but natural and are not fit for human consumption. I thought I was eating healthy when I was just poisoning myself and my hair. Anyway, there you have it. I have not worn my topper for 9 months. I proudly wear my natural hair and am so grateful to have the freedom not to hyper-obsess about it anymore. This has been an unexpected victory which I never anticipated a few years ago. So here's my testimonial. I whipped hair loss for now. Stop eating soy. Read food labels because you will discover it in the majority of processed foods.
