A hair care device for use in untangling hair includes a body portion and a plurality of substantially parallel flexible bristles made of soft plastics material and projecting from the body portion. The bristles are arranged such that over at least a part of the area of bristles, some of the bristles are of shorter length. The bristles and the shorter length bristles are interspersed over the at least part of the area of bristles.

In various exemplary embodiments a method for determining the waviness index of hair is provided. The method may comprise the steps of determining and/or establishing at least one hair examination region in at least one digital image, in which hair is depicted, determining a plurality of different brightness values in the hair examination region, and determining the waviness index of hair on the basis of the plurality of brightness values.

The present disclosure relates to a multi-phase liquid agent for the non-chemical smoothing and de-curling of keratin fibers, in particular human hair, which has an aqueous-alcoholic phase and a non-aqueous phase existing separately therefrom and which can be applied as a spray, and a method for non-chemical smoothing or de-curling of keratin fibers using the agent.
