Abstract: An applicator is provided for applying a hair product, for example, a hair coloring product in the form of a gel or of a cream. The applicator includes an array of brush members, such as teeth or bristles, on an application face. The application face is preferably impermeable to the hair product and is capable at least temporarily holding the product that is to be applied to the hair. The application face has a stepped profile with at least two discrete levels so that contact of the application face with the hair, and movement thereof between the roots and the tips of the hair, generates on the hair a coloration pattern which is formed of at least two locks of hair having different degrees of coloration.
