Abstract
Hair treatment formulations, dispensing devices, and methods provide safer, cleaner, less complicated alternatives to existing permanent hair dye kits for home or salon use. In some embodiments, a hair treatment formulation includes a dispersion and an aqueous solution. The dispersion includes a continuous phase including an oil as well as a dispersed phase including a pigment precursor and a catalyst for increasing an oxidation rate of the pigment precursor. The aqueous solution includes an oxidant for oxidizing the pigment precursor to a pigment. The dispersion and the aqueous solution form an emulsion for hair treatment upon their combination, the emulsion including the pigment. In some embodiments, the dispersion and the aqueous solution are distributed between compartments of a dispensing device for simultaneously combining the dispersion and the aqueous solution in a mixing tip to form the emulsion including the pigment through a dispensing action of the dispensing device.
