Hair dying system and methods for accurately blending and developing hair dye

摘要

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.
