1. A method for dyeing keratinous fibers, wherein the mixture is applied to said fibers, wherein said mixture is prepared of: - a coloring composition comprising at least one oxidation dye precursor, u oxidizing composition comprising at least one chemical oxidizing agent - for at least one of the compositions which are sprayed from a container under pressure, - a mixture of two compositions comprising at least one thickening polymer chosen from: - an associative polymer - anionic non-associative vnogo polymer selected from anionic polymers containing sugar units, anionic polymers containing no sugar units selected from crosslinked homopolymers or copolymers of acrylic or methacrylic acid, crosslinked homopolymers of 2-acrylamido-2-methylpropanesulfonic acid and their crosslinked acrylamide copolymers, homopolymers of ammonium acrylate or copolymers of ammonium acrylate and acrylamide, taken separately or as mixtures thereof - and their smesey.2. Method according to the preceding claims, characterized in that said associative thickening polymer (s) chosen from associative polyurethanes, which are in particular cationic or nonionic, associative cellulose derivatives which are particularly cationic or nonionic, associative vinyllactams, associative unsaturated polyacids and especially those which contain at least one hydrophilic unit of olefinically unsaturated carboxylic acid type, and at least one hydrophobic unit of (C) lkilovogo ester, and copolymers comprising among their monomers, α, β-monoethylenically unsaturated carb1.
