Abstract
Abstract The present hair dye is adapted for dyeing, re-dyeing and also for differently dyeing natural as well as artificial hair without showing a difference in the coloring result, or hue. For this purpose so-called oxidation dyes and soluble catalysts especially metal complex compounds are combined in a solvent wherein the components are at least partially solved to produce a solution and/or mixture wherein the proportion by weight of the catalyst is preferably kept below 1%. The hair dye according to the invention is especially suitable for application out of a spraying device such as an atomizer or an aerosol container whereby the pressure supplying means do not contain any oxygen.
