Provided is a hairdressing appliance, which includes a portable treatment unit provided with a gripping device and a heat and steam treatment system configured for heating hair and for applying steam to this hair, a base remote from the portable treatment unit, and connection device between the base and the portable treatment unit configured for supplying the portable treatment unit at least with electricity from the base. The hairdressing appliance includes a circuit board for controlling the treatment system arranged in the base and a system of communication between the control circuit board and the treatment system. The hairdressing appliance enables, for example, the straightening, curling, or crimping of hair and chiefly aims to reduce the weight and the bulk of the portable treatment unit so as to make it easier to handle during styling.
