Abstract

The present invention relates to methods and systems for hair dying. The system includes at least two reservoirs containing different hair dying components in predetermined concentrations, the containers including outlets having cross-sectional areas which are sized relative to the concentration of the component contained in the reservoir and the amount of that component needed to react with the remaining components. The measuring device calibrated with respect to the concentrations of the hair dye components and the cross-sectional areas of their respective reservoir outlets, permits rapid and accurate dispensing of the hair dye components in the proper quantities. In a preferred arrangement, the measuring device is provided on a blending board so that the components can be blended together immediately upon dispensing.

Dependent claims

A hair dying system, comprising:

an oxidative dye component having a preselected concentration of a developable oxidative hair dye;
a first dye reservoir containing said oxidative dye component;
a developer component having a preselected concentration of a developer capable of developing said oxidative hair dye;
a first developer reservoir containing said developer component;
dispensing means for dispensing said oxidative dye component from said first dye reservoir and for dispensing said developer component from said first developer reservoir, said dispensing means including a first orifice defining an outlet from said first dye reservoir, said first orifice having a cross-sectional area sized active to said concentration of oxidafire hair dye, and a second orifice defining an outlet from said first developer reservoir, said second orifice having a cross-sectional area sized relative to said concentration of said developer;
and a blending means for blending together is dispensed quantity of said oxidative dye and developer components, wherein said blending means comprises a substantially fat-surface, inert material having a measuring means for measuring a dispensed quantity of at least one of said developer and said oxidative dye component disposed thereon, and wherein said blending means is detached from said first dye reservoir and said first developer reservoir.

A method of formulating a hair dye composition, comprising the steps of:

providing an oxidative dye component having a preselected concentration of a developable oxidative hair dye, said oxidative dye component being contained in a first dye reservoir;
providing a developer component having a preselected concentration of a developer capable of developing said oxidative hair dye, said developer being contained in a first developer reservoir;
dispensing a quantity of said oxidative dye component from said first dye reservoir and a quantity of said developer component from said first developer reservoir with at least one means for dispensing said oxidative dye component from said first dye reservoir and for dispensing said developer component from said first developer reservoir, said dispensing means including a first orifice defining an outlet from said first dye reservoir, said first orifice having a cross-sectional area sized relative to said concentration of oxidative hair dye, and a second orifice defining an outlet from said first developer reservoir, said second orifice having a cross-sectional area sized relative to said concentration of said developer;
wherein said quantities are dispensed onto a blending means for blending together a dispensed quantity of said oxidative dye and developer components, wherein said blending means comprises a substantially flat-surfaced, inert material which is detached from said first dye reservoir and said first developer reservoir;
measuring said dispensed quantities of said oxidative dye and developer components with a measuring means for measuring a dispensed quantity of at least one of said developer and said oxidative dye component, said measuring means being disposed on said blending means and wherein said blending means is detached from said first dye reservoir and said first developer reservoir;
and intimately intermixing said dispensing quantities of said oxidative dye and developer components to develop said hair dye.
