There sure are!
-EO Clarifying shampoo (suitable for hard water, too)
-Cream of Nature Clarifying (great for hard water, as well)
-Qhemet Biologics Egyption Wheat Grass Tea (grest, but no chelating ingredients so not so good for hard water)
I am sure there are others but these are the 3 I know of and have personal experience with.
Honestly though, I use Kenra Clarifying with does have SLS and it is never drying. I use it with every wash for one lather. Different strokes for different folks I guess.
