Abstract: A computer-implemented method for generating feedback for a user performing hair care, the computer-implemented method includes receiving a sequence of images of a face of the user during a hair care process. The method also includes analysing a haircare performance by determining: a facial expression of the user in the sequence of images, and one or more performance parameters and/or one or more haircare events based on the facial expression of the user. The method also includes generating feedback for the user during the hair care process based on: the haircare performance, and the one or more performance parameters and/or the one or more haircare events. The feedback comprises one or more of an instruction, a recommendation, or guidance to improve the hair care process.

Abstract: A computer-implemented method for generating feedback for a user in performing personal care includes receiving a sequence of images of a face of a user and a personal care implement. The method also includes determining one or more implement parameters by tracking the personal care implement using the sequence of images. The method also includes determining one or more facial apparent emotional expressions of the user using the sequence of images. The method also includes analysing a personal care performance based on i) the one or more implement parameters and the one or more facial apparent emotional expressions of the user in a current personal care session and ii) the one or more implement parameters and the one or more facial apparent emotional expressions of the user from a previous personal care session, and determining one or more performance parameters or one or more personal care events.

Abstract: A computer-implemented method for generating feedback for a user performing haircare includes receiving a sequence of images of a head of the user and a haircare implement, the haircare implement being a hairstyling implement. The computer-implemented method also includes determining one or more implement motion parameters by tracking a position or an orientation of the haircare implement using the sequence of images. The computer-implemented method also includes determining a detangling event if one or more of: linear velocity, angular velocity, linear acceleration, and angular acceleration of the haircare implement is less than a corresponding detangling motion threshold, the detangling event being an event in which tangles from hair of the user are being removed. The computer-implemented method also includes generating feedback for providing to the user based on the determined detangling event.

Abstract: A hair treatment composition comprises particles having a first non-aqueous phase and, retained within said first non-aqueous phase, a second hydrophilic phase which is an aqueous solution, dispersion, emulsion or a solid or liquid having a log P value less than 1, said second phase comprising a hair benefit agent, wherein said first non-aqueous phase has a melting point of from 30° C. to 100° C.

Abstract: Rinse off hair treatment compositions comprise particles wherein at least 90% by weight of the particles have an average maximum dimension of from 10 nm to 300 ?m, the particles comprising a silicone wax having one or more C3 to C40, branched or unbranched, saturated or unsaturated, optionally substituted hydrocarbon groups and the wax having a melting point of from 30° C. to 100° C. The compositions can be used in a method of treating hair which comprises: applying to the hair particles wherein at least 90% by weight of the particles have an average maximum dimension of from 10 ?m to 300 ?m, the particles comprising a silicone wax having one or more C3 to C40, branched or unbranched, saturated or unsaturated, optionally substituted hydrocarbon groups and the wax having a melting point of from 30° C. to 100° C.; and heating the hair to a temperature above the melting point of the particles. The method can act to condition the hair.
