Abstract
A hair-care device includes at least two jaws, a first jaw and a second jaw. The first and second jaw are elongated and hinged together so as to be able to shift between an open position and a closed position in which opposing working surfaces define a hair treatment region. An electric heating element is attached to at least one of the working surfaces. The first jaw includes at least one friction bar which is able to move along an adjacent working surface and which is adapted to engage with an opposing element of the second jaw to create, when the jaws are closed, a traction region which generates a traction force which exceeds the traction force generated by the treatment region as the device is moved over a lock of hair.
