Claim 0:
1. A water-soluble article for hair care comprising:
a. a water-soluble pouch defining an internal volume comprising:
i. a water-soluble, non-continuous, fibrous facing sheet comprising a perimeter, an outer surface, and an inner surface; and
ii. a water-soluble, non-continuous, fibrous backing sheet comprising a perimeter, an outer surface, and an inner surface;
wherein the facing sheet and the backing sheet comprise a thermal seal joining the facing sheet to the backing sheet along at least a portion of the perimeters to form the internal volume;
wherein the fibrous facing sheet and the fibrous backing sheet comprise a plurality of fibrous elements that are inter-entangled or otherwise associated with one another;
wherein the plurality of fibrous elements comprise a polymeric structurant that is thermally sealable without the addition of an adhesive or other composition; and
wherein the outer surfaces and/or the inner surfaces of the facing and backing sheets comprise from about 5 to about 25 bonding points per cm2 distributed across the facing sheet and/or backing sheet; wherein the bonding points extend completely or partially through the facing and/or backing sheet and the facing sheet is not bound directly to the backing sheet at the bonding points;
wherein the water-soluble fibrous facing sheet and backing sheet are substantially free of a surfactant; and

b. a plurality of prills within the internal volume comprising:
i. from about 1% to about 60%, by weight of the prills, of a cationic surfactant chosen from behentrimonium methosulfate, brassicamidopropyl dimethylamine, behentrimonium chloride, stearamidopropyl dimethylamine, and/or behenamidopropyl dimethylamine;
ii. from about 10% to about 90%, by weight of the prills, of a fatty alcohol;

wherein the prills comprise a melting point of greater than 45° C.
