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.
