Query: KInd to the Hair

Most shampoos contain sulfates, which amount to detergent. My long, thick hair is dry in the first place, so typical shampoos yield a stripped/frayed/frizzed look and it takes a lot of compensating conditioners, etc., to overcome that.Thanks to the lack of sulfates in this product, my hair is much more tamed and soothed when I use this, and I require far fewer post-shampoo products to achieve a nice look.While I am beating up on sulfates, they also strip out hair color. This product is very kind to both hair and hair color.One final note: this particular shampoo seems to lather better than other sulfate-free formulas, including others by Avalon.
