Abstract

The oxidation hair dye composition for oxidative dyeing of hair is based on a combination of developer substance and coupler substance and contains at least one 3,4,5-triamino-pyrazole derivative compound selected from the group consisting of 1-methyl-3,4,5-triaminopyrazole, 3,5-diamino-1-methyl-4-methylaminopyrazole, 3,5-diamino-4-(2'-hydroxyethyl) amino-1-methylpyrazole and physiologically compatible, water-soluble salts of the foregoing pyrazole derivative compounds, as the developer substance. The invention also includes novel 3,4,5-triaminopyrazole derivative compounds.
