Abstract: A method of and system for recommending one or more products to a consumer from a plurality of products, the system comprising: a user interface; and a processor configured to: provide a list of questions for the consumer at the user interface, each question having a defined set of answers; calculate a consumer score for each question using the answer chosen by the consumer at the user interface; calculate a recommendation score for each question, using the consumer score; and select the one or more products for recommendation to the consumer based on the recommendation score.

Abstract: A system for measuring the diameter of a human hair (50), the system comprising: a mobile device (20); and a reference card (10) including a hair attachment mechanism (11a, 11b); the mobile device configured to convert an image of a human hair attached to the reference card by the attachment mechanism into a measurement of the diameter of the human hair, using the size of the reference card itself and/or the size of a calibration marker (12) on a surface of the reference card as a size reference.

Abstract: A hand held imaging device for measuring characteristics of hair and scalp, comprising a housing with a high magnification optic for obtaining magnified images of surface characteristics of hair fibers, said high magnification optic comprising a first lens and a first light source, and a low magnification optic for obtaining magnified images of the scalp and hair, said low magnification optic comprising a second lens and a second light source, wherein the high magnification optic has a fixed focal length and a slot for locating hair fibers in frame such that the hair fibers are in focus and wherein the device further comprises a viewing means, selected from an integral viewing means, an external viewing means and a combination thereof.

Abstract: A self-assessment device comprising an series of rough patches which may be contacted by the user and compared with the roughness of a hair sample in order to provide an indication to the user as to the relative state of the hair sample. A kit comprising a hair care composition and a self-assessment device as described above. A package for a hair care composition comprising a device as described in any preceding claim. A method for assessing the state of hair by contacting a hair sample and then contacting one or more rough patches on a device according to any of claims 1-6 and then concluding as to which of the rough patches has the most similar roughness to the hair sample.
