A composition for the oxidative dyeing of hair based on a gel vehicle and a dye mixture dissolved therein, wherein the gel vehicle contains A) from 12 to 16% by weight of oleic acid, B) from 12 to 30% by weight of nonyl phenol, ethoxylated with from 2 to 6 moles of ethylene oxide, and/or of fatty alcohol, having from 12 to 20 carbon atoms, ethoxylated with from 2 to 6 moles of ethylene oxide, C) from 8 to 14% by weight of fatty alcohol having from 10 to 20 carbon atoms, D) from 4 to 18% by weight of ethanol and/or isopropanol, and E) from 16 to 70% by weight of water. The new composition allows the ammonia it contains to escape more slowly, and it darkens less, when hydrogen peroxide is added, than the known gel hair dye compositions.
