<p>The present invention is related to an aqueous oxidative colouring composition for keratin fibres especially human hair. The inventors of the present invention have surprisingly found out that a composition comprising at least one oxidative dye precursor and optionally at least one coupling agent and an aqueous emulsion of divinyldimethicone/dimethicone copolymer with an internal phase viscosity of more than 1 x 10 8 mm 2 /s measured at 0.01 Hz and at about 25°C and at least one alkyl ether or ester or amine alkyl amine or quaternary ammonium compound colours hair excellently and improves hair shine, combability and manageability and especially hair coloured with such composition has less flyaways. Additionally it has been observed that hair coloured homogeneously. Accordingly, the present invention is an aqueous hair colouring composition comprising at least one oxidative dye precursor, optionally at least one coupling agent, an aqueous emulsion of divinyldimethicone/dimethicone copolymer with an internal phase viscosity of more than 1 x 10 8 mm 2 /s measured at 0.01 Hz and at about 25°C and at least one compound according to general structure
