Are sulfate-free and vegan conditioners actually better?

Sulfate-free matters mostly for color-treated and curly hair, where it helps preserve color and natural oils; for many hair types the difference is modest. "Vegan" and "paraben-free" are formulation choices rather than performance guarantees. Several of the higher-rated picks here are sulfate- or paraben-free, but the consensus we read ties satisfaction more to moisture and slip than to those labels alone.
