Abstract
A brush for applying makeup includes a multitude of bristles wedged into the spirals (9) of at least two branches (10, 11) of a helically twisted metal wire, which form the core (12) of the brush. Over at least a portion of the brush, bristles (8a, 8b) are provided the surface of which has at least one groove extending substantially from the base to the tip, and the cross sections of the bristles have different shapes, of at least two types. As a result, the bristles (8a, 8b) having different cross-sectional shapes are spaced apart differently with respect to the mid-plane (14) of the spiral, and there is a space (15) between the bristles to permit penetration of the eyelashes (16) or hair.
