Abstract
A method for treating hair to impart thereto a conditioning benefit, the method involving applying to the hair an azlactone-functionalised copolymer consisting of vinyl azlactone and methacryloyl polydimethylsiloxane monomers; and allowing the copolymer to chemically bond through nucleophilic reaction of the azlactone onto the hair, the monomers of the copolymer being present in amounts sufficient to achieve both bonding to the hair and imparting conditioning properties.
