A brush for applying make-up, particularly mascara, including a shaft provided at one end with a core (6) formed by two metal wires (7, 8) twisted together and having bristles (9) squeezed therebetween such that they extend transversely to the core axis. At least some of the brush bristles (9) have an L-shaped cross-section so that the portion of each bristle (9) which is squeezed between said twisted core wires is flattened either outwards when the arms of the L are pushed apart, or inwards when they are pressed together. In either case, the stiffness of the bristle is reduced and the spacing between the bristle and the wire helix is advantageously increased, whereby a random distribution of bristle cross-sections is achieved.

La brosse pour appliquer un produit de maquillage, en particulier du mascara, comprend une tige équipée, à une extrémité, d'une âme (6) formée par deux branches (7, 8) en fil métallique, torsadées suivant des spires entre lesquelles sont emprisonnés des poils (9) s'étendant transversalement par rapport à l'âme. Au moins une fraction des poils (9) de la brosse présente une section transversale en L de sorte que la zone d'un poil (9) coincée entra les spires de l'âme métallique subit un aplatissement soit par effet de déploiement lorsque l'angle entre les branches du L s'ouvre soit par effet de pliage, lorsque l'angle encre les branches du L se ferme, cet aplatissement réduisant la rigidité du poil d'une part, et, d'autre part, augmentant de façon préférentielle l'écartement du poil par rapport à la nappe hélicoïdale formée par la spire en créant ainsi une implantation désorganisée de la section des poils.
