This is a fascinating question! I have been skeptical for some time about the cocomidapropyl betaine shampoos I've tried by Avalon Organics. They suds up quite a bit (though it's still hard to distribute through the hair, so I use more than I want to). Afterwards, my hair feels dry. I've wondered: what really IS the chemical reality that makes this better than a sulfate? Or is it a myth? Does anybody know?

I have no answer, but I'll tell you this much: the next 'poo I try might just have a sulfate or sulfonate in it, just further down on the ingredients list.

Wurly and proud!
