The plurality of bristles tufts can be transferred to a providing unit, in which the bristles tufts are arranged in a pre-defined tuft pattern and may be over-molded by injection molding in order to form at least a brush head. A device suitable to perform the method comprises at least an immersion unit to apply oil to bristles and an airflow-using transportation unit.
