Bests & Worsts Reviews from Amazon

I've been using the OGX Thick & Full + Biotin & Collagen Shampoo & Conditioner for more than a year. I LOVE the smell of it, and it does a good job. I noticed about a year ago that my hair is falling out by the handfuls! I honestly can't believe I have any left! But I had radiation treatments about a year ago and I blamed the hair loss on that. Now I read that an ingredient in this product, DMDM Hydantoin, causes hair loss, eye problems, and breathing problems! I've also had an eye issue (red, watery, itchy) that I've been to the Dr. twice for and it just won't clear up. It'll be interesting to see if it clears up now. I won't be using this any more. *****UPDATE: I switched to Nioxin. My hair falls out at a NORMAL rate now and I have lots of new growth. Also, the eye condition cleared up. You be the judge.
