    摘要: Disclosed is a method for achieving a recallable hair deformation. A composition is applied onto hair, comprising at least one active agent, which, alone or in combination with further compounds, is able, after application to the hair and after carrying out the treatment of hair in accordance with the present invention, to provide a shape memory effect. The hair is brought into a defined (permanent) shape and the permanent shape is subsequently fixed by means of inducing a chemical or physical change of the applied agents, wherein after a desired or undesired deformation, the memory shape of the initial memory shape may be recovered by means of a physical stimulation. Suitable active agents are for example macromers which may be cross-linked to provide shape memory polymers, wherein the permanent shape is fixed by means of the chemical cross-linking of the macromer, providing a shape memory polymer, which possesses at least one transition temperature Ttrans. Suitable active agents are also shape memory polymers, which have hard segments which may be cross-linked by physical interactions having a first transition temperature T′trans, which preferably is at least 10° C. above room temperature, and soft segments having a second transition temperature which preferably is at least 10° C. below T′trans. In addition to the permanent hairdo, a second (temporary) shape can be impressed. Furthermore, disclosed is a method for the recovery of a once programmed permanent hairdo, which has been brought into a temporary shape or which has been deformed in any other way.

    摘要: A method for the provision of a recallable hair transformation using shape-memory polymers is disclosed. In this respect a composition which comprises a macromer or prepolymer which is cross-linkable to a shape-memory polymer is applied onto the hair and the hair is brought into a defined (permanent) shape and subsequently the permanent shape is fixed by means of the chemical cross-linking of the macromer or prepolymer under formation of the shape-memory polymer. The macromer or prepolymer contains segments which are cross-linkable by means of chemical bonds as well as thermoplastic segments which are not chemically cross-linkable. The shape-memory polymers do possess at least one transition temperature TTrans. In addition to the permanent shape of a hairdo a second (temporary) shape can be impressed. Furthermore, disclosed is a method for the recovery of a previously programmed, permanent shape of a hairdo, which has been temporarily brought into a temporary form or which has been deformed in a different manner.
