The Dyson Airstrait is designed to dry and straighten hair at the same time, saving you valuable time in your hair styling process. It moves from wet to finished with one tool and it doesn't rely on hot plates or extreme heat. It works by using a heated, downward airflow to align hair for a smooth, natural-looking straight finish. It even has sensors that regulate temperature and adjust airflow depending on whether hair is between the arms.

The device uses a high-speed motor to generate enough pressure to straighten as it dries, and the built-in LCD display shows airflow and heat settings while you style. The arms can be locked to pre-dry roots and add volume, and the built-in auto-pause feature reduces noise and energy use when the device isn’t in contact with hair. It can even be used on dry hair to give it a touch up or to restyle it completely.
