Styling Techniques
- Wet to Dry Straightening: Ensure hair is towel-dried. Select Wet Mode and your preferred temperature. Pass the straightener slowly through sections of hair, allowing the airflow to dry and straighten simultaneously.
- Dry Styling: For refreshing or light straightening on dry hair, select Dry Mode.
- Root Volume: Use the lock feature to close the arms of the machine. With the arms locked, gently pre-dry hair at the roots to create volume before unlocking for full straightening.

Intelligent Heat Control
The Dyson Airstrait features intelligent heat control, which regulates the airflow temperature 16 times per second. This precise regulation ensures that hair is straightened without extreme heat, helping to maintain hair strength and reduce breakage.
Intuitive Airflow
The machine is designed with intuitive airflow, sensing when hair is between its arms. When hair is detected, the airflow automatically adjusts to the optimal level for styling. When no hair is present, the airflow reduces to a lower setting, contributing to quieter and more efficient operation.
LCD Screen
The high-definition colour LCD screen provides clear visual feedback on airflow and temperature settings, allowing for easy monitoring and adjustment during styling.

Lock Feature
A sliding button allows you to lock and unlock the arms of the straightener. This feature is particularly useful for pre-drying hair or creating root volume when the arms are locked.

Auto Pause
For energy efficiency and convenience, the machine will automatically pause airflow after three seconds of inactivity. Simply move the straightener to restart the airflow.
Maintenance
Regular maintenance ensures optimal performance and longevity of your Dyson Airstrait straightener.
- Cleaning the Filter: Periodically check and clean the filter located at the base of the handle. Dust and hair buildup can restrict airflow and affect performance. Refer to the full user manual for detailed filter cleaning instructions.
- Wiping Surfaces: Use a soft, damp cloth to wipe down the exterior surfaces of the straightener. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the straightener in a dry place, away from direct sunlight and extreme temperatures. Ensure the arms are locked for compact storage.
