The PROluxe You hot air brush features intelligent StyleAdapt technology that learns, personalises and adjusts the heat to the unique styling needs of your hair. During styling, the sensor on the barrel measures the temperature of the hair more than 1,800 times and learns your individual hair type and styling technique. The sensor feeds the temperature values into an intelligent microprocessor and continuously adjusts the heat of the airflow in real time to the ideal styling temperature for your hair. So you can be sure to always achieve results that last all day. This is personalised styling, just for you.
