Abstract

A compact, stable shampoo composition containing a cationic polymer and from about 20% to about 40%, by weight, of a surfactant system. The shampoo composition is substantially free of sulfate-based surfactants. The surfactant system contains acyl glutamate and one or more co-surfactants. The weight ratio of acyl glutamate to total surfactant can be less than 0.55.
