The present invention is related to an aqueous conditioning composition for hair comprising at least one alkyl ether alkyl amine or alkyl ether alkyl quaternary amine and at least one compound selected from fatty acid fatty alcohol esters and arylated silicones. Present invention is also related to the use of at least one alkyl ether alkyl amine or alkyl ether alkyl quaternary amine compound for hydrophobizing surface of keratin fibers, especially human hair and especially damaged keratin fibers surfaces. Conditioning composition of the present invention can be in the form of a shampoo, cleansing - conditioning composition, or in the form of a conditioner used after washing hair with cleansing compositions. Accordingly the object of the present invention is that a conditioning composition comprising at least one compound according to general structure. Formula (I), wherein R1 is a saturated or unsaturated, straight or branched alkyl group with 8 to 24 C atoms, R2 is a straight or branched alkyl group with 1 to 4 C atoms which may be substituted, A is O and B is selected from. Formula (II), wherein R3 and R4 are the same or different, H or an alkyl with 1 to 4 C atoms, hydroxyl alkyl with 1 to 4 C atoms and di hydroxyl alkyl with 2 to 4 C atoms and. Formula (III), R5,R6 and R7 are the same or different, an alkyl with 1 to 4 C atoms, hydroxyl alkyl with 1 to 4 C atoms and di hydroxyl alkyl with 2 to 4 C atoms, and X is an anion such as chloride, bromide, methosulfate, and at least one compound selected from fatty cid fatty alcohol ester according to general structure R40 C (O) O R41 wherein R40 is a saturated or unsaturated, straight or branched alkyl group with 7 to 23 C atoms and R41 is a saturated or unsaturated, straight or branched alkyl group with 8 to 24 C atoms and arylated silicone, and its use for hydrophobizing keratin fibers especially human hair.La présente invention porte sur une composition aqueuse de conditionnement des cheveux, comprenant au moins une
