Abstract: In the method of hair color consultation, actual individual images of a person are continuously recorded by a video camera and are input into a computer in a continuous sequence in real time. Automatic image editing and processing is carried out in real time, in which the computer continuously marks hair regions of the individual images by an automatic analysis of close and similar pixel color values, of contiguous texture, and/or of contiguous morphological properties, and changes hair color of the hair regions according to predetermined specifications. Then the modified individual images with the changed hair color are displayed on the at least one screen and/or touch screen in real time so that the desired hair color may be selected. An apparatus for performing the method is also described.

Abstract: 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.

Abstract: 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.
