I have been using the L'oreal Everpure line of shampoo and conditioner for the past couple years. Sulfate free and for color treated hair. Is in the purple-ish color tubes.

I like it. It is a very creamy product, so I always put a dab in my hand and add water, lather between hands and then apply to hair. Otherwise would be too thick to apply directly to hair. Leaves hair nice, and smells good. A little goes a long way.
