I checked Sulfate free non-lathering cleanser: Deva No-poo, but maybe that is really more like conditioner washing?
In the winter, when I'm more wavy I use mop C-system sulfate free shampoo, really nice stuff.
The CoN's really vary, label to label, and even seem to get reformulated occasionally, they're hard to keep up with.
