So I just went back and looked through all the products I've loved and hated, and ohguesswhat... the ones I loved were either protein free or only had silk proteins or keratin, and the ones I hated were all wheat/oat/other proteins. Go figure. I've actually HAD a keratin treatment, and my hair loved that.
