ABSTRACT:
An apparatus for measuring the incremental grooming force experienced by a hair tress during combing, and supplying an instantaneous readout of that force. The apparatus includes a comb or brush with strain gages attached to it which change resistance when mechanically deformed. The change in resistance is electrically measured to provide an indication of incremental grooming force. A continuous monitor is connected to the resulting electrical signal to provide an instantaneous indication of incremental grooming force. A method for using the apparatus to reduce the creation of split ends during hair grooming is also provided.
