A material treatment device intended for use for human or animal hair includes a plurality of rods arranged circumferentially as part of a rod barrel and a handle attached to the rod barrel for rotatable support thereof. A mechanism is provided to rotate the rod barrel in a first direction and a second mechanism is provided to rotate each of the rods separately from the rod barrel in a second direction opposite the first direction. The material being contacted by the rods during use of the hair treatment device rolls away from the contacted rod in the second direction or permitting each of the rods to freely spin during rod barrel rotation. The device can also include bristles that move with respect to the rod barrel or are fixed thereto, the bristles moving with the rod barrel rotation.

An apparatus manipulates the shape of hair using dielectric heating. Typically,the apparatus includes opposing first and second electrodes respectively provided on first and second arms that are movable towards and away from one another. Drive circuitry supplies electrical energy to the first and second electrodes, to cause an alternating electric field to be produced in the vicinity of the electrodes in use, and thereby cause dielectric heating of hair placed between the electrodes in use. Sensing circuitry senses a change in coupling of energy from the alternating electric field to the hair during heating of the hair. Control circuitry controls the drive circuitry to vary the electrical energy supplied to the first and second electrodes in dependence upon the sensed change in coupling. A related method manipulates the shape of hair using dielectric heating.
