The present specification provides for an agent for dyeing keratinic fibers. The agent includes, in a gel-like carrier at least one oxidation dye precursor. The gel-like carrier includes at least one emulsifier combination. The emulsifier combination includes one or more non-ionic polyethoxylated emulsifiers selected from ethoxylated fatty alcohols containing between 8 and 22 carbon atoms, ethoxylated castor oil, or combinations thereof, and one or more polyethylene glycols having an average molecular weight between 100 and 100,000 grams per mole (g-MOL−1). The gel-like carrier also includes at least one polymeric thickener selected from homopolymers of acrylic acid or methacrylic acid, copolymers of acrylic acid or methacrylic acid with C1-C4 alkyl esters of acrylic acid or methacrylic acid, or combinations thereof.
