The present invention relates to a dye composition comprising: * at least one oxidation dye precursor; * at least one polycondensate of ethylene oxide and of propylene oxide having the structure (A) below H--(O--CH.sub.2CH.sub.2).sub.a--(O--CH(CH.sub.3)--CH.sub.2).sub.b--(O--CH- .sub.2CH.sub.2).sub.a'--OH (A) in which formula a ranges from 2 to 150 and b ranges from 1 to 100; and * at least one oxyethylenated rapeseed fatty acid amide comprising from 1 to 20 mol of ethylene oxide; * the oxyethylenated rapeseed fatty acid amide(s)/polycondensate(s) of formula (A) weight ratio ranging from 1 to 20. The invention also relates to a dyeing process using this composition (free of oxidizing agent) after mixing with a composition comprising an oxidizing agent. Another subject of the invention is a two-compartment device, the first compartment comprising the composition according to the invention, free of oxidizing agent, and the second compartment containing a composition comprising at least one oxidizing agent.
