Clarifying cleansers that contain sulfates rid the hair and scalp of silicones and petro-chemicals. That said, I have talked about my search for an all natural clarifying cleanser and I am intrigued with the Aubrey Organics Green Tea Clarifying Shampoo. Currently I am using Organic Black Soap by Eli which is in liquid form. I picked this up from my local flea market and I am not disappointed. I have realized that my hair responds well to black soap as appose to castille soap. I wash my hair with the Organic Black Soap by Eli and than follow with rinsing my hair and scalp with Bragg Apple Cider Vinegar mixed with water (half & half). I have gotten good results without my hair feeling stripped.I like to think of clarifying cleansers as a reviver for hair. They bring the pH balance back to a normal level and promote clean scalp which assist in growth. Keeping our hair and scalp clean is a must if we want to prevent breakage and knotting. Sometimes the residue of products is what is causing the hair to feel rough and look dull which if this is also true for the ends of the hair strand that translates into knotting and breakage. Try clarifying whether it be once a week, every two weeks or once a month, your hair will tell you what it needs.
