A pneumatic hairbrush for people and pets releases a powder mixture containing perfume, fragrance and/or other active compositions directly onto the hair or fur during brushing. 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. The powder mixture containing the active ingredient is poured into the internal cavity and disseminates over the flexible deformable membrane. A cover is inserted through a second opening. Delivery of the powder mixture is activated during brushing or through manually depressing, where the flexible deformable membrane is deformed and compresses the internal cavity causing the powder mixture to be pneumatically forced within the plurality of apertures of the brush bristles or around the outside surfaces of the bristles, and released.
