The brush comprises a wand equipped at one end with a core (6) formed by two twisted branches (7,8) of metal wire. Between the turns of the branches, bristles (9) extending transversely with respect to the core, are trapped. At least a fraction of the bristles (9) of the brush has a transverse section in the shape of an L. The zone of the bristle (9) wedged between the turns of the metal core is flattened either through the effect of unfolding when the angle between the branches of the L opens or through the effect of folding when the angle between the branches of the L closes. This flattening reduces the rigidity of the bristle on the one hand and, on the other hand, preferentially increases the spacing of the bristle with respect to the helical ply formed by the turns. Thus, the flattening creates a disorganized arrangement of the section of the bristles.
