Abstract
The oxidation hair dye composition is made by mixing a viscous creamy hair dye-containing carrier and a fluid preparation in a weight ratio of dye-containing carrier to fluid preparation of 2:1 to 1:3. The viscous creamy hair dye-containing carrier has a viscosity of at least 10,000 mPa.s and contains 0.01 to 12 percent by weight of a combination of developer substance and coupler substance and 15 to 60 percent by weight of a thickener mixture containing fatty alcohols having from 10 to 24 carbon atoms, fatty acid esters, petrolatum, thickened polyacrylic acid derivatives, nonylphenol ethoxylated with 2 to 8 moles of ethylene oxide, fatty acids, starch and/or spermaceti. The fluid preparation contains 0.1 to 20 percent by weight of an oxidizing agent and 0.01 to 6 percent by weight of a nonionic polymer of formula (I),
