Hair composition and method for dying hair using a composition comprising a polymer dye, said polymer dye obtainable by polymerizing: (a) a first dye monomer which has a structure according to Formula (I) where Y is selected from -CONH- or -CH 2 CH(OH)CH 2 -NH- and R 1 is selected from H, alkyl; aryl; benzyl; halogen; ester; acid amide; and, CN, and (b) a second monomer according to a structure according to Formula (II) where X is an organic bridging group covalently connecting the amine to the alkene moiety of the monomer, preferably X is -CO 2 (CH 2 ) n - where n = 1 to 6; where R 5 is selected from: H, alkyl; aryl; benzyl; halogen; ester; acid amide; and, CN, preferably R 5 is CH 3 or H; and where R 2 , R 3 , and R 4 are independently selected from H or alkyl, preferably at least two of R 2 , R 3 , and R 4 are alkyl. |
