| titleOfInvention |
Copolymers for improving color intensity and washfastness of temporary hair dyes |
| abstract |
A method for dyeing hair includes applying a polyvinyl amine copolymer solution to the hair; and applying a hair dye composition to the hair. A hair dye composition includes an aqueous base fluid; a polyvinyl amine copolymer; and an anionic or cationic hair dye. A method of making a hair dye composition includes mixing a polyvinyl amine copolymer and an anionic or cationic hair dye into an aqueous base fluid. |
