ABSTRACT:
A mascara brush and method of manufacture thereof provides a mascara brush with bristle fibers that are split into numerous fragments. The mascara brush is made with bristle fibers having longitudinal voids. The brush is then conditioned by passing a rotating wire wheel over the bristle fibers . The wire wheel splits the bristle fibers into numerous bristle fragments. The conditioned brush is softer to the touch than the original mascara brush. The conditioning can be applied to the entire brush or one or more zones of the brush. The conditioning can be shallow, so that only the bristle tips are conditioned, or deep, so that a substantial length of the bristle is conditioned.
