Over the weekend I bought some Dawn dish detergent. I was standing at the sink and noticed the bottle said "Quick Sudsing Action" and thought of SLS. I looked at the ingredients and SLS was the second one. I recalled looking at ingredient listings on shampoos and sometimes SLS is the 3rd ingredient. I was REEEALLY shocked because for years... most of my life... I've pretty much been washing my hair with expensive DISH DETERGENT!!!!!!!!!! Yikes! It's funny how we've pretty much all been wondering at some point what we WERE doing wrong to our hair... now I know!
