1. A dissolvable solid fibrous shampoo article comprising fibrous elements comprising:
a. from about 1% to about 50%, by weight on a dry article basis of a polymeric structurant;
b. from about 10% to about 90%, by weight on a dry article basis, of a surfactant system comprising a primary anionic surfactant and one or more co-surfactants; wherein the primary anionic surfactant comprises a glutamate surfactant;
wherein the surfactant system is free of sulfate-based surfactants; and
c. optionally a cationic polymer comprising a weight average molecular weight from about 100,000 g/mol to about 2.5 million g/mol as measured by gel permeation chromatography and a charge density of greater than 0.5 meg/g as measured according to the Charge Density Test Method;
wherein the fibrous article is substantially free of a lamellar structure as determined by the Lamellar Structure Test Method in a conditioned, dry state;
wherein the fibrous article comprises a hand dissolution of less than 15 strokes according to the Hand Dissolution Test Method;
wherein the fibrous elements comprise filaments;
wherein the plurality of fibrous elements are inter-entangled or otherwise associated with one another to form the fibrous structure.
