Claim:
A method of enhancing the colour perception of artificially coloured hair comprising applying a composition comprising an effective amount of an aminosilicone onto said hair, wherein said aminosilicone is selected from the group consisting of silicones according to the formulas (I) to (IV) and mixtures thereof: Wherein: m and n are numbers wit a sum (n+m) ranging from about 2 to about 2000, n is a number ranging from about 1 to about 1999, and m is a number ranging from about 1 to about 1999; and R1, R2, R3, which may be identical or different, are chosen from a hydroxyl radical, C1-C4 alkoxy radicals or methyl, A is chosen from linear or branched C3-C8 alkenyl radicals, R4 is chosen from H, phenyl, linear or branched C1-C4 alkyl radical, benzyl, or a linear or branched (C2-C8)NH2; G is chosen from H, phenyl, hydroxyl, or a C1-C8 alkyl; Wherein: R1, R2, R4, A, G are defined as above; m and n are numbers with a sum (m+n) ranging from about 1 to about 2000, n is a number ranging from about 1 to about 1999 and m is a number ranging from 0 to about 1999, R5 is Me or A-NH—R4; Wherein: R 3 is a monovalent hydrocarbon radical from C 1 to C 18 ; R 4 is a hydrocarbon radical; Q − is a halide ion; r is a number from about 2 to about 20; s is a number from about 20 to about 200; Wherein: R is selected from alkyl group consisting of about 1 to about 10 carbon atoms and an aryl group consisting of about 6 to about 10 carbon atoms; R2, R4, and A are as defined above; Where a+b is greater than about 4, and b is different than 0.
