Wet to dry straightening, with air. No hot plates. No heat damage¹. Powerful, directional airflow smooths and aligns hair. Straightens from wet to dry, simplifying your routine. For a natural straight finish. Style from wet Straighten and dry hair – at the same time. Three pre-set temperatures – 80°C, 110°C and 140°C – take your hair from wet to finished style, with one machine. Refresh from dry No hot plates. No heat damage.¹ Dyson's 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.² 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. 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. 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 up to 3.6kPa of air pressure, powerful enough to straighten hair as it dries. LCD screen High-definition colour display shows airflow and temperature settings, for easy reference when styling. 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. Auto-pause After three seconds of inactivity your machine will automatically pause. Simply move the machine to restart the airflow. More than a plug The PRCD plug (Portable Residual Current Device) is engineered for your safety and comfort when using the Dyson Airstrait™ straightener. Dyson engineers designed the plug to include key electronics elements in it. By moving this to the plug, it removed weight and bulk from the machine itself. The plug is currently Dyson's best solution to enable a lightweight and compact product that enables wet-to-dry straightening. The straightener’s powerful air drying technology for wet to dry use requires a PRCD plug to test the electrical current for safety. Such plugs are on a variety of electrical appliances, particularly in proximity to water or water vapour. For your safety, press TEST and RESET every time before you use your Dyson Airstrait™ straightener. See the step-by-step instructions in your online user manual.
