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.

The invention relates to a cosmetic refill (20) intended to be inserted in a removable manner into a housing (22) in a device (2) for treating the hair and to the associated treatment device (2). The cosmetic refill (20) comprises a body (23) that has a first wall (40) and a second wall (38) opposite the first wall (40), and at least one coupling relief (50, 52) that extends from each of the first wall (40) and the second wall (38). The coupling relief (50) on the first wall (40) is intended to cooperate with a first surface (46) of the housing (22) when the first wall (40) is introduced into the housing (22). The coupling relief (52) on the second wall (38) is intended to cooperate with a second surface (44) of the housing (22) when the refill (20) is brought into a use position by pivoting in the housing (22) about a pivot axis (B).
