Abstract
A hairbrush for people and pets releases a perfume, fragrance and/or other active compositions including insect repellant, hair conditioning composition, dye composition, moisturizing ingredients, or antibacterial compounds when brushed or activated by manually depressing a cover. The brush includes a flexible deformable membrane that carries brush bristles and has a plurality of apertures for delivery of the active composition and is fitted within a first opening of an internal cavity in a brush base. A porous sponge being saturated with the active ingredient is inserted over the flexible deformable membrane. A cover is inserted through a second opening and rests upon the porous sponge. Brushing action deforms the flexible deformable membrane and squeezes the sponge releasing the active ingredient. Manually depressing the cover also releases the active ingredient even though the bristles may not be in direct contact with the hair at that time.
