Your routine, simplified. Dyson Airstrait dries and straightens simultaneously from wet. Engineered to create a natural straight finish for multiple hair types. No hot plates. No heat damage (when used in wet to dry mode).
Key Benefits
- Style from wet: Straighten and dry hair – at the same time.
- Three pre-set temperatures – 175°F, 230°F and 285°F – to take your hair from wet to finished style, with one machine.
- Refresh from dry: Touch-up or refresh your style from dry. Style at 250°F, 285°F or use the optional Boost mode for maximum shine.
- Lock feature: Slide the button to lock and unlock the arms of your machine. Use with the arms locked to gently pre-dry hair and create volume from the roots.
- No wait time: Unlike hot plates that need to heat up, styling with air means it is ready to style when you are.
- Intuitive airflow: Airflow when you need it. Your machine senses when hair is between the arms and automatically drops to low airflow when it's not – for quieter, more efficient styling.
- LCD screen: High-definition colour display shows airflow and temperature settings, for easy reference when styling.
- Auto-pause: After three seconds of inactivity your machine will automatically pause. Simply move the machine to restart the airflow.
- Technology 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
- Intelligent heat control: Glass bead thermistors, located in the machine arms, regulate airflow temperature up to 30 times per second, to prevent extreme heat damage and protect hair’s natural shine.
- Ioniser: Negatively-charged particles are delivered from root to tip with high-velocity air, to help reduce static in the hair.
- Dyson Hyperdymium motor: A 13-blade impeller spins up to 106,000rpm, propelling 11.9 liters of air through the machine per second. This generates 3.6kPa of air pressure, powerful enough to straighten hair as it dries. 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 heat damage.¹
- 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.
Caveats:
- ¹When used in wet to dry mode.
- ²When used in wet to dry mode vs. hot plate straighteners which operate with extreme heat.

Dyson solves problems that others ignore. Dyson has been researching the science of hair styling for almost a decade, investing over £100m into hair laboratories across the globe and employing thousands of hair scientists, engineers and professionals. These expert teams have studied in detail everything from the structure of hair to airflow dynamics whilst understanding thermal, mechanical and chemical damage – and the subsequent effects on hair health. At the core of Dyson technology is the drive to engineer products that use less reliance on heat and improve the overall styling experience, creating hair products for every hair type and every style with less damage.
