I've tested several shampoos recently that were sulfate-free but left my hair a tangled, rough mess. Most of these had intense, rich, incredible lather which usually suggests a high intensity of surfactants, whether they are sulfates or not.

Would you rather have a sulfate-free poo, no matter how gentle it is--all because you are trying to avoid sulfates OR a gentle poo, whether it contains sulfates or alternate surfactants?

Why?
