Abstract: 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.
