Abstract: A haircare appliance has a housing having an air inlet and an air outlet, an airflow generator for generating an airflow from the air inlet to the air outlet, and a heater for heating the airflow. The haircare appliance has an airflow temperature module for obtaining a value indicative of a temperature of the airflow at the air outlet, a distance sensor for sensing a distance to hair within a flow path from the air outlet and a temperature sensor for sensing a temperature of the hair. The haircare appliance has a moisture estimation module configured to estimate, based on received output values from the airflow temperature module, the distance sensor and the temperature sensor, a moisture content of the hair.

Abstract: A hair styling appliance includes elements moveable relative to each other, including a first arm and a second arm coupled together for reciprocal movement towards and away from each other, the first and second arms being arranged to receive hair within a region between each other. A sensor arrangement includes at least a first sensor component mounted to at least one of the elements and is configured to sense, using the first sensor component, a change in relative position of at least two of the elements. The sensor arrangement outputs a first signal indicative of an angle and/or a distance between the first arm and the second arm based on the sensed change in relative position.
