Abstract: A composition for dyeing keratin fibers that contains 0.1 to 30 percent of at least one substantially pure plant dye material obtained using solvent or supercritical CO2 extraction combined with 0.01 to 5 percent of a metal or mineral salt capable of acting as a mordant as a two part hair color system. The addition of the encapsulation of one or both components allows the use of the plant dye in combination with the metal or mineral salt in a one part hair color system.
