Not a product I would purchase again

I purchased this product as it is free of many of the harmful chemicals I have been trying to avoid. And who knows, maybe it is good for someone with super short hair. I personally have hair to the middle of my back and need two handfuls of this shampoo just to begin to feel it is cleaning my hair. I used it 3 times to be sure but each time, no matter how much product I used, my hair didn't come clean and I felt there was a build up of product once I dried my hair. I tried a different shampoo today with the same conditioner I had been using and my hair looks and feels clean with no build up. My conclusion? This shampoo is not good for me. I will be taking it back.
