Abstract: The compositions of the present invention relate to improved shampoo compositions having from about 5 to about 50 weight percent of a detersive surfactant, at least about 0.025 weight percent hollow particles having a mean particle size of less than about 80 microns, and at least about 20 weight percent of an aqueous carrier.

Abstract: Leave-in hair cosmetic compositions for enhancing hair volume comprise non-spherical microparticles exhibiting a mean particle size of less than about 100 &mgr;m in its longest dimension, a water-soluble or water-swellable polymer, and an aqueous carrier such that the combination of the polymer and the microparticles results in a film-forming network. Also disclosed are methods for enhancing hair volume, and more particularly for enhancing hair volume with leave-in aqueous cosmetic compositions which contain non-spherical microparticles of less than 100 &mgr;m in its longest dimension, a water-soluble or water-swellable polymer and an aqueous carrier. The disclosed compositions provide improved hair volume, body, bounce, fullness, springiness, and texture in addition to providing good hair conditioning and styling benefits. Fluid-encapsulated, flexible microspheres which exhibit a mean particle size of less than about 300 &mgr;m in diameter may also be included in the compositions.

Abstract: Leave-in hair cosmetic compositions for enhancing hair volume comprise fluid-encapsulated, flexible microspheres exhibiting a mean particle size of less than about 300 &mgr;m in diameter, a water-soluble or water-swellable polymer, and an aqueous carrier such that the combination of the polymer and the microspheres results in a solid continuous or semi-continuous film network. Methods for enhancing hair volume, and more particularly for enhancing hair volume, comprise applying leave-in aqueous cosmetic compositions which contain spherical, flexible, fluid-encapsulated particles of less than about 300 &mgr;m in diameter, a water-soluble or water-swellable polymer and an aqueous carrier. The compositions provide improved hair volume, body, bounce, fullness, springiness, and texture in addition to providing good hair conditioning and styling benefits.
