摘要： 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.

摘要： A hair styling apparatus having a pair of closable jaws to engage a user's hair. The jaws have complementary shapes with a first said jaw defining a curved ridge and a second said jaw defining a curved recess. One or both of the jaws includes a heater such that, when said jaws are closed, hair is heated in a heating region between the ridge of the first jaw and the recess of said second jaw. The second jaw has a curved longitudinal surface having an active cooling region. The heating region is located on the forward curve and the active cooling region is located on the reverse curve.

摘要： The invention relates to hair dryers. Various techniques for improving air flow in hair dryers are described, including a hair dryer providing laminar flow air. In another variant a hair dryer has a two air flow channels: one a hot air channel the other a cool air channel, with the cool air channel circumscribing the hot air channel. The nozzle end of the hair dryer is arranged such that the cool air channel extends forward of the hot air channel outlet. This allows a hair dryer to be placed close to, or on, a person's hair/head without and risk of burning the person's head. A hair dryer with external power supply is also described which reduces the weight of the housing held by a user.

摘要： A hair styling appliance for dual supply voltage operation is described comprising a body having at least one arm bearing a hair styling heater (560), wherein the hair styling heater comprises one or more heater electrodes (630,632,634,636) for heating the hair styling heater. A first power input is connectable to a battery power source (564) and a second power input is connectable to a mains powered source (561). The first power input and the second power input are each coupled to at least one of the one or more heater electrodes. Such a hair styling appliance is useable for styling when coupled to the mains powered source and when coupled to the battery power source increasing the versatility of the appliance.

摘要： 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.

摘要： The present invention relates to a method for dyeing hair fibres, in particular a method which involves coating hair fibres with a hair dye composition and directing radio frequency electromagnetic radiation to the coated hair fibres to cause heating within the coated hair fibres by dielectric loss. The present invention also relates to kits and appliances for use in connection with the method, as well as the use of radio frequency electromagnetic radiation in reducing the effective dye-treatment time for hair fibres. In one aspect, there is provided a method of dyeing hair fibres, said method comprising the steps of: i) coating one or more hair fibres with a hair dye composition; and ii) directing radio frequency electromagnetic radiation having one or more frequencies from 1 MHz to 300 MHz to the one or more coated hair fibres to cause heating within the one or more coated hair fibres by dielectric loss. Preferably, the hair dye composition used in step i) is a permanent or demi-permanent hair dye composition that may be prepared by combining a dye lotion containing one or more dye precursors and an activator solution containing an activating agent, wherein the activating agent in the activator solution converts the one or more dye precursors in the dye lotion to active dye agents.
