Abstract
A brush for applying a cosmetic product, in particular for applying mascara to eyelashes or dye to hair, has an elongate core (2) formed by the helical winding of two strands of metal wire (3), with bristles (4) radially implanted in the core and being tightly held between the twisted strands. The brush is of an overall cylindrical shape and comprises at least one concave cutback (7) which holds the product during the wiping and which is obtained by clipping the brush. Such a brush allows a make-up to be obtained which is copious, regular and elongating.
