Abstract: A generally cylindrical non-spherical dense body having rib members, used for agitating hair coloring dye within a mixing and application hair coloring dye container. When the container is shaken, the agitator travels randomly inside the container agitating the hair coloring dye liquids together and more thoroughly mixing the entire contents of the container. The shape of the agitator and protruding ribs improve agitation and prevent the blockage of the container applicator orifice when applying the hair coloring dye. The agitator can be dropped into the hair coloring dye container or provided with the container.
