The Dyson Airwrap uses a powerful digital motor that creates the Coanda effect, as well as intelligent temperature control that measures the temperature up to 40 times per second. This allows you to style your hair without fear of heat damage. The combination of the hair's moisture, a strong airflow, and a temperature that is always kept below 150°C, you can style and dry simultaneously. Connect to the MyDyson app to complete your hair profile and create a custom curl sequence. Using the aerodynamic Coanda effect, the Dyson Airwrap id creates a continuous airflow that creates vortices, pulling your hair towards the head and coiling it. The curling head can be set to rotate in one direction or the other. For styling voluminous curls and waves. The Dyson Smoothing Brush uses the Coanda effect to draw hair to the surface of the brush. The air is distributed along the strands of hair using the same airflow technique that a hairdresser uses.
