A hair styling apparatus includes a first and a second arm each having a heatable plate and an arm member. The first and second arms are moveable between a closed position, in which the heatable plate of the first arm is adjacent the heatable plate of the second arm, and an open position, in which the heatable plates of each arm are spaced apart. The heatable plate of at least one of the arms is coupled to a respective arm member about a pivot arranged to allow the heatable plate to move relative to the respective arm member about an axis transverse to the length of said respective arm member such that the plate pivots.

A hairstyling device is provided. The hairstyling device includes a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to a tress of hair of a user via the hair-contactable surface. The hairstyling device includes a controller configured to determine that the hair contact member is moving along the tress from a first end of the tress towards a second end of the tress. The controller is configured to, based on the determining, control heating of the hair contact member to cause the operating temperature of the hair contact member to change as the hair contact member moves along the tress from the first end of the tress towards the second end of the tress.

Apparatus for manipulating the shape of hair using dielectric heating is provided. Typically, the apparatus comprises opposing first and second electrodes respectively provided on first and second arms that are movable towards and away from one another; and drive circuitry for supplying 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 may also be provided for sensing a change in coupling of energy from the alternating electric field to the hair during heating of the hair; and control circuitry for controlling 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 of manipulating the shape of hair using dielectric heating is also provided.

The present invention provides a heating apparatus for heating a load. The heating apparatus comprises a heater having a heating element for receiving electrical power and for converting the electrical power into heat to heat a heating surface of the heater. The heating apparatus also comprises a temperature sensor for sensing and outputting a measurement of the temperature of the heating element, a power actuator for providing the electrical power to the heating element of the heater, a power sensor for sensing and outputting a measurement of the power provided to the heating element by the power actuator, and control circuitry for controlling the power actuator to control the power delivered by the power actuator to the heating element. The control circuitry is configured to receive the temperature measurement from the temperature sensor, receive the power measurement from the power sensor, combine the temperature measurement and the power measurement, and control the power actuator in dependence upon the combined temperature measurement and power measurement. This ensures that the temperature of the heating surface is constant throughout a period when the load is applied.

A hairstyling device is provided. The hairstyling device includes a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to hair via the hair-contactable surface. The hairstyling device includes an inertial measurement unit, IMU, configured to output signals dependent on movement of the hair contact member. The hairstyling device includes a controller configured to receive a signal from the IMU indicating movement of the hair contact member along a tress of hair between a first end of the tress and a second end of the tress, process the received signal to determine a speed of the hair contact member, and control heating of the hair contact member based on the determined speed.

A hairstyling device is provided. The hairstyling device includes a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to hair via the hair-contactable surface. The hairstyling device includes a controller configured to monitor power draw associated with heating of the hair contact member during heating of hair of a user via the hair-contactable surface. Based on the monitored power draw, one or more hair damage parameters indicative of damage of the heated hair are calculated. The controller is configured to control the hairstyling device based on the one or more calculated hair damage parameters.

The present invention teaches a hair straightening system including formulations that will safely and effectively straighten curly hair for at least 2-3 months after a single application, despite frequent washings of the hair. Methods for obtaining said formulations are disclosed. Hair straightening systems including shampoo and one or more conditioners are also provided.

The invention concerns a device (10) for treating the hair, comprising two arms (12, 4) that are able to move relative to one another between a first opened configuration for inserting hair between the arms (12, 14) and a second closed configuration for treating the hair, at least one of the arms (12, 14) comprising: —a shell, —a support housed in said shell, —a treatment plate supported by the support, —an electrical heating element received in a housing defined between the support and an inner face of the treatment plate, —a first sealing element sandwiched between the support and the treatment plate, —a second sealing element, wherein the second sealing element is sandwiched between the support and the shell.
