The Dyson Airstrait replaces the usual two-step routine of blow-drying and then straightening with one tool. It suits people who straighten most days and want to start from towel-dried hair instead of dry hair. The defining feature is the absence of hot plates: two jets of air, angled downwards, dry and straighten at the same time.

In its favour
- Dyson claims up to 66% reduction in frizz and flyaways when used wet to dry.
- Air is directed down at a 45° angle, and a new integrated comb adds tension for a sleek finish.
- Wet and Dry modes, four heat settings and three airflow settings are listed.
Good to know
- It only straightens, so it cannot diffuse curls or add round-brush volume.
- Wattage is not stated, and the listed weight of 923 g is heavy for a hand-held tool.
Our take
How the Airstrait straightens without plates
A conventional straightener clamps hair between heated metal. The Airstrait instead pushes two powerful jets of air down through the hair at a 45° angle, which Dyson says gives the right tension to straighten. A 13-blade impeller spins at up to 106,000 rpm in the Hyperdymium motor, and glass bead thermistors measure the airflow temperature up to 500 times per second.
The newer version adds an integrated comb that increases tension through each section, aimed at a sleeker finish with more control.
Wet mode, Dry mode and the settings
Wet mode is for wet to dry styling. Dyson recommends starting at 140°C in Wet mode, pre-drying the roots, then finishing on a cool setting to lock the style. Dry mode is for touching up hair that is already dry. Across both, there are four heat settings and three airflow settings, and the listed maximum temperature setting is 200°C.
Dyson claims you can save up to 8 minutes per style compared with separate drying and straightening, and quotes up to 66% less frizz and flyaways in wet to dry mode against air drying. These are the maker's figures, with footnotes on the listing.
Weight and practical limits
The listed item weight is 923 g, heavy for a tool you hold open around each section. The listing does not give wattage, cable length or warranty terms on this page.
It is also a single-purpose tool. It cannot diffuse curls, it has no round brush for volume and it does not curl. Dyson's own guidance says curly and coily hair can be straightened with it, while straight and wavy hair keeps a natural look.
Airstrait or a dryer with a smoothing nozzle
If you want smooth rather than poker-straight hair, a dryer may do the job. The Dyson Supersonic r comes with a smoothing nozzle and flyaway attachment and can also diffuse. The Shark SpeedStyle Pro includes a FrizzFighter Finishing Tool and QuickSmooth Brush. The Airstrait makes most sense when a flat, straight finish is the daily goal.
Verdict
Choose the Dyson Airstrait if you straighten most days and want to go from wet to straight in one pass without hot plates. If you want a smooth blow-dry with volume, curls on other days or a lighter tool, a dryer such as the Dyson Supersonic r or Shark SpeedStyle Pro is the more flexible buy.
