An apparatus and method for formulating and dispensing customized hair colorant products from a plurality of available constituent materials in an oxygen-protected manner. The apparatus includes a plurality of oxygen-protected constituent material sources, at least one oxygen-protected delivery outlet with a delivery coupling for selective attachment with an oxygen-protected container, a dosing mechanism providing fluid communication between each constituent material source and the delivery outlet, and a programmable formulation device for activating the dosing mechanism to selective dispense appropriate volumes of one or more of the constituents into the oxygen-protected container in an oxygen-protected manner. The invention provides customized hair colorant product in a protected manner, thereby enabling the product to be utilized at a point of purchase or at any time at a remote location, or to be ordered from a remote location and/or shipped to a remote location, without degradation of the product or performance. |
