What is the i.d. curl personalized curling sequence and how do I activate it?

The i.d. curl personalized curling sequence is a feature that tailors wrapping and styling times to your personal hair profile using the MyDyson app. To activate it, you must first complete the tutorial in the MyDyson app to unlock the feature, then slide the power button up and release it. The sequence will automatically run, including a cold shot to set the curl, and airflow will automatically reduce when the sequence is complete. (Pages 3–4, 6)
