The invention relates to mascara compositions. In one embodiment, it relates to a dye-free and wax-free mascara composition that lasts more than one day when applied to eyelashes, is resistant to water, and does not noticeably thicken eyelashes on application. In another embodiment, it relates to a wax-free mascara composition comprising solid particles of a film-forming acrylic polymer dispersed in a cosmetically acceptable aqueous medium, in which the film-forming acrylic polymer are capable of forming a film having a water-uptake, after immersion for 10 minutes in water at 25° C., of less than 25 wt. %, and wherein the composition has a viscosity, measured at 25° C., at a shear rate of 200 s−1, of from 4 Pa·s to 18 Pa·s. In other embodiments, the invention relates to make-up kits, articles, and methods for making-up and/or coloring human hair, such as eyelashes and/or eyebrows, using these compositions.
