Definitions

  • the present invention relates to a method to measure and/or adjust combing resistance of fibers by using a brush
  • the brush comprises: a brush handle; a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, wherein a certain number of the bristles are movable; an activation means which moves the movable bristles from their original positions to different positions; wherein the brush further comprises at least one of the following: a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position; an indication to match at least one position of the movable bristles to at least one fiber type and/or at least one treatment type; or the combination thereof.
  • Keratinaceous fibers may be damaged over time. Damages may be caused by environmental factors, including air pollution, sun exposure, chlorine from water pool, and/or rain. Damages may also be caused by applying to the fibers grooming (cosmetic), chemical and/or mechanical treatments. When hair fibers are damaged, the hair fibers may have undesirable conditions of, for example, "fly-away hair", "split end", and/or color fade.
  • Assessing the condition including the degree of damages caused to keratinaceous fibers is of interest in order to understand the impact of various environmental factors as well as the impact of the cosmetic (grooming), chemical and mechanical treatments onto keratinaceous fibers. Such assessment is also of interest in order to demonstrate the efficacy of treatments used for preventing and/or repairing keratinaceous fiber damages.
  • Several attempts for assessing keratinaceous fiber damages, using different methods and/or devices, have already been reported.
  • Measuring combing resistance of keratinaceous fiber, especially its friction and/or detangling, is one of common ways to assess keratinaceous fiber conditions. Generally speaking, damaged and/or curled keratinaceous fibers cause increased combing resistance compared to healthier and/or straight keratinaceous fibers.
