ABSTRACT:
A system for mixing and dispensing oxygen sensitive hair dye consists of concentrates in a sealed air-tight system using preferably 3-8 dye concentrates in collapsible bags having an oxygen barrier. The dye concentrates, along with oxygen activating liquids, are sufficient to produce an infinite number of hair dye formulations, thereby avoiding buying and stocking many bottles of specific color dyes. For formulating the dye mixtures, exact charges, i.e., volumes measured to within 1 ml, are raised from the bags and discharged. Each bag is removably connected, in an air-tight seal, to a separate precision lift pump whose piston lift excursion may be selectively set to determine the volume of the dye charge.
