A haircare appliance is provided for detecting a hair moisture content. The haircare appliance includes a processing element, at least one light emitting element emitting at least two wavelengths, and a sensor element, wherein the light emitting element is adapted to irradiate a portion of hair to be treated. The sensor element is adapted to receive a sensor reading from an acquisition region of the irradiated hair and generate a sensor signal dependent on the sensor reading, and includes a spectral sensor element. The processing element is adapted to determine a moisture content of at least the irradiated portion of the hair from the sensor signal.

In one aspect the invention is arranged to provide a hair treatment apparatus adapted to reduce the temperature of hair. This apparatus includes at least one thermal energy storage core arranged to draw heat out of hair wherein said at least one thermal energy storage core is arranged to cool hair to a temperature below 0 Celsius.

Disclosed is a hair iron comprising: a pair of bodies each including a fixing portion and a driver rotatably coupled to one side of the fixing portion; and a hinge portion which is coupled to the other side of the fixing portion of the pair of bodies and adjusts the angle of the pair of bodies, wherein the driver comprises: a rotating plate coupled to one end of the fixing portion so as to be rotatable in a longitudinal direction from the other end of the fixing portion to the one end thereof, as a rotary shaft; a heating module located on one surface of the rotating plate; and a cooling module located on the other surface of the rotating plate. Accordingly, by simultaneously or sequentially applying a hot/cold process, thermal damage to hair may be minimized and setting power may be increased.

A hair curling iron relating to the field of hairdressing devices is provided, which includes a handle and a hair curling component having a plurality of specifications and detachably connected to the handle. The handle includes a housing, a driving component disposed in the housing, and a rotating component of which one end rotates in the housing. A working end of the driving component is connected to the rotating component, one end of the hair curling component adjacent to the handle is provided with a connecting post and a plurality of probes. The connecting post is detachably inserted into another end of the rotating component, and the plurality of probes are correspondingly connected to a circuit in the handle through the rotating component.

A haircare appliance is described comprising a heater assembly and a controller. The heater assembly comprises a heating element and a sensor to sense a temperature of the heater assembly. The controller is configured to determine the presence or absence of hair in contact with the heater assembly based on the sensed temperature.
