I've been using this delicious shampoo for quite a while now. By using the product as a normal shampoo, you get minimal to no result. Because of this, I was a little disappointed at first. There was little else on the label as well. In the end, I let the product move in longer. I built this slowly to find out what works for me. Now I leave this product for about 5/10 minutes. This reduces the warm yellow tone in my hair! And that was what I wanted!
