  • Patent number: 6250312
    Abstract: A novel hair highlighting brush suitable for use in applying color treatment at home or at the hair salon for selected strands of hair separated from a head of hair is provided having a sheet of flexible tubing having at one of the tubing a detachable brush portion that accepts the color treatment and at the other end of the tubing a detachable hair securer so that the selected strands of hairs of different thicknesses can be accepted. The flexible tubing allows both ends to contact so that the selected hairs receive the color treatment while the brush is pulled from the top of the scalp along the length of the selected hairs. Optionally, a pump applicator is affixed atop the removable brush portion so that the color treatment may be applied continuously when the brush is pulled vertically along the selected strands of hair.
