An aqueous hair color composition for oxidatively coloring hair in twelve minutes or less, wherein said composition is prepared by combining a dye mixture and a developer mixture, said aqueous hair color composition comprising 0.01-2.0% (combined weight) of the total composition of primary intermediates and couplers, a free alkalinity concentration of 0.20-0.75 meq/gram, and a hydrogen peroxide concentration of 4-6% by weight of the total composition; and a hair coloring kit containing separate containers of an aqueous dye mixture and an aqueous developing mixture for use with said dye mixture.

Method and compositions for coloring hair

A single composition for simultaneous coloring and highlighting hair to provide hair fibers having variations in tonality and hue, comprising, 1-10% inorganic persulfate, 1-20% hydrogen peroxide, 0.001-20% of at least one primary intermediate and, optionally, at least one coupler for the formation of oxidation dyes; and 0.01-20% of one or more surfactants; as well as a one step method for simultaneously color and highlighting hair to provide hair fibers having variations in tonality and hue comprising, combining, immediately prior to use, a powder composition comprised of at least one alkali metal or alkaline earth metal persulfate, an aqueous developer composition comprised of hydrogen peroxide; and an aqueous based colorant composition comprised of at least one primary intermediate and, optionally, at least one coupler for the formation of oxidation dyes; and applying the mixture to the hair for a period of time sufficient to cause coloration and highlighting of the hair.
