The Dyson Airstrait is a straightener that skips the hot metal plates. Two apertures on the inside of each arm shoot high-velocity air at your hair from a 45-degree angle, drying and straightening in the same pass. Wet Mode has three temperature settings for different hair types, ranging from 175°F to 285°F, and Dry Mode adds a Boost setting for touchups. A Cool Mode sets the finished style with room-temperature airflow.

A powerful hair tool that’s well worth the entry price and beyond
Straightening from wet used to mean drying your hair with a blow dryer first, then running a flat iron over each section afterward. Two steps, two devices, and roughly 30 to 45 minutes for anyone with long or thick hair. The Airstrait handles both jobs at once. You start with towel-dried hair straight out of the shower and finish with a smooth, straight style in the same session.
Every flat iron on the market runs on the same principle. Two hot ceramic plates clamp around your hair, pressing it flat as the heat resets the hydrogen bonds in the strands. Dyson swapped the plates for airflow. Two 1.5mm apertures along the inside of each arm force air at 3.6 kilopascals of pressure at a 45-degree downward angle. The air stream is what straightens the hair, not direct contact with hot metal.
