The Hummingbird works and plays well with virtually every professional or home formulation that you would normally use in a bottle. This includes most professional and home glosses, liquid toners, liquid semi-permanent hair colors, light lotions, light gel formulations, and virtually all box colors. The Hummingbird does not work well with colors specifically formulated for bowl and brush applications, direct dye masks that are very thick, or gels that become too thick. If you can pick up a wad of color in your hand, it will not work in The Hummingbird. See our full list of approved brand hair colors here.
