The Dyson Airstrait straightener has been engineered to simplify your routine to straighten as it dries, making it ideal for every day fast styling or the days where you don’t have as much time to spend on your hair - with two styling modes, Wet and Dry.

In each of these modes there is a different temperature and airflow setting combinations - this helps when straightening wet hair. The higher airflow is needed to dry simultaneously.

These differences include:  

Temperature:

The temperatures in Wet mode are 80°C (175°F), 110°C (230°F), and 140°C (285°F). 

In Dry mode, the temperatures are 120°C (250°F), 140°C (285°F) and BOOST for an additional optional boost for maximum styling impact. 

Airflow:

Airflow speeds in Wet mode are High (11.9 L/s) and Low (9.2L/s). 

In Dry mode, these are High (10.9L/s), and Low (9.2L/s).

To change between styling modes, press the Mode select button. The onboard LCD screen will show a Wet animation or a Dry animation. The animations identify which of these two modes is active. 

What is the difference between 140 degrees in Wet mode and 140 degrees in Dry mode?

The difference between each Wet and Dry mode is the airflow speed. When straightening wet hair, higher airflow is needed to dry simultaneously. Hence, the airflow options are: High (11.9 L/s) and Low (9.2L/s). In Dry mode, lower airflow is needed as we’re not drying, so the airflow options are: High (10.9L/s) and Low (9.2L/s).
