Pioneering Dyson technology

No hot plates.
No extreme heat.1

Our latest hair care technology uses high-pressure airflow to straighten hair as it dries. Air is precisely heated and projected evenly through the tress as you style – with no need for extreme heat.1

Directional airflow to
smooth and align

Airflow is projected downwards at a 45° angle to create the tension needed to align hair for a smooth end style – with less damage and breakage.2

Inside the machine

    Intelligent heat control

    Glass bead thermistors, located in the machine arms, regulate airflow temperature up to 16 times per second, to prevent extreme heat damage and protect hair’s natural shine.

    Dyson Hyperdymium™ motor

    A 13-blade impeller spins up to 106,000rpm, propelling 11.9 litres of air through the machine per second. This generates 3.6kPa of air pressure, powerful enough to straighten hair as it dries.

Your routine, simplified

The Dyson Airstrait™ dries and straightens hair simultaneously. Take hair from wet to finished look – with one machine.

Why straighten from wet?

    Style reset

    When hair is wet, its hydrogen bonds are more pliable and easier to 'reset'. Using a combination of moisture and airflow, hair can be styled effectively – without extreme heat.1

    The science of shine

    Using lower temperatures and resetting the hair's bonds from wet mean its internal structure is protected, so it can reflect more light, for a shiny finish.
