Abstract: A hair care appliance including, a body, a heater, a PCB and a primary fluid flow path extending from a primary fluid inlet into the appliance to a primary fluid outlet out of the body wherein the PCB and heater are in fluid communication with the primary fluid flow path and the PCB is upstream of the heater. A fan unit may be provided and the fan unit is upstream of the heater and may be upstream or downstream of the PCB. A thermal barrier may be provided between the PCB and the heater. The thermal barrier may be in thermal communication with the PCB and functions as a heat sink for the PCB.
