PURPOSE: Provided is a composition for the oxidation dyeing of keratin fibers, such as human keratin fibers and further such as the hair, comprising, in a medium that is suitable for dyeing and that is free of glycerol and of cationic synthetic thickening polymer comprising at least one fatty chain, at least one oxidation dye, at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one particular polyol. CONSTITUTION: A composition for the oxidation dyeing of a keratin fibre comprises, in a medium that is suitable for dyeing, at least one oxidation dye and at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one polyol of the formula (Ia) in which: R1, R2, R3, and R4 are chosen from, independently of each other, a hydrogen atom, C1-C6 alkyl radicals, C1-C6 monohydroxyalkyl radicals, and C1-C6 polyhydroxyalkyl radicals; A is chosen from linear and branched alkylene radicals containing a number of carbon atoms "n" ranging from 1 to 18, and optionally interrupted with a number of oxygen atoms "z" ranging from 0 to 9; and m is chosen from 0 and 1; wherein the total number of carbon atoms in both radical A and all of the substituents R1, R2, R3, and R4 is greater than or equal to 2; wherein the molecular weight of the at least one polyol ranges (i) from 95 to 500, if m is equal to 0, or if m and n are equal to 1, or if m is equal to 1 and A is a linear alkylene radical and n is equal to 2 and z is equal to 0; or (ii) from 140 to 500, if n is greater than or equal to 2, or if m is equal to 1 and n is equal to 2 and z does not equal 0; or (iii) from 90 to 500, if m is equal to 1 and n does not equal 1 or 2 and z is equal to 0, or if m is equal to 1 and A is a branched alkylene radical and n is equal to 2 and z is equal to 0; and wherein the composition contains no glycerol and no cationic synthetic thickening polymer comprising at least one fatty chain.
