Abstract

An add-on hairbrush for people, pets and livestock comprises a brush base with an internal cavity that includes a connection means. A vessel that houses a composition, liquid or powder, containing active ingredients is attached to the brush base. The composition containing active ingredients is transferred to the internal cavity of the brush base for release directly onto the hair during brushing. Delivery of the liquid/powder is activated during brushing through automatic deformation of a flexible deformable membrane or through manual depression of a deformable brush cover. The flexible deformable membrane includes bristle elements and delivery apertures or spray elements that carry and align with central spray apertures of spray elements for delivery of the composition containing active ingredients onto the hair. The vessel can act as a handle, and is a separate tube or container, that is preferably squeezable for transfer of the composition to the brush base.
