Abstract: The invention refers to an apparatus (120) for accessing hair characteristic while brushing hair of a subject, wherein the apparatus comprises a vibration measurement providing unit (121) for providing a vibration signal indicative of a result of a vibration measurement performed by one or more vibration sensors (112) integrated into a hairbrush (110) comprising a plurality of bristles (111). The vibration measurements are performed by the vibration sensors during a brushing of the hair using the hairbrush and are indicative of vibrations of the bristles of the hairbrush during the brushing. A hair characteristic determination unit (122) then determines a hair characteristic based on the vibration signal.
