ABSTRACT:
An electrical hair dryer (5) comprises a housing (10) with an air inlet (11) and an air outlet (12) between which are arranged a mechanism for delivering a flow of hot air, comprising an air circulation mechanism (13) and air heating mechanism (14), and detection mechanism (20) for measuring a radiation emitted by the hair (8). The hair dryer also includes a control mechanism (18) which jointly acts on the air circulation 13) and the heating (14) mechanisms, for regulating the flow of hot air during drying as a function of the measurements of the emitted radiation, which effects simultaneous variation in the flow rate and temperature of the air flow as a result of the measurements of the emitted radiation.
