This Plum Copper Airstrait is sold as a gift edition, but the tool inside is Dyson's wet to dry air straightener. It is especially relevant for people with fine hair who dislike clamping it between hot plates, because the Airstrait uses two jets of air rather than heated metal. Dyson recommends starting at 140°C in Wet mode, a lower point than the fixed 185°C of the ghd straighteners, and that recommended starting heat is the key reason to consider it for delicate hair.

In its favour
- No hot plates press the hair, which suits anyone wary of clamping fine hair.
- Four heat settings and three airflow settings, with a recommended 140°C start in Wet mode.
- The maker says it automatically pauses when not in use.
Good to know
- A listed 820 g makes it heavier than most plate straighteners.
- The finish is a straight blow dry, which may lack the flat sleekness some want.
Our take
Why air suits fine hair
Fine hair responds quickly to heat and can look flat or limp after pressing. With the Airstrait, air is directed downwards at 45° through the hair while an integrated comb adds tension, so the hair is shaped as it dries rather than squashed. Dyson cites up to 66% less frizz and flyaways and twice the shine compared with air drying.
Dyson's explanation is that hydrogen bonds in wet hair are pliable, so moderate heat can reset them as the hair dries.
Settings and routine
There are 4 heat settings, 3 airflow settings and separate Wet and Dry modes, with an auto pause function. The suggested routine is to towel-dry, pre-dry the roots, glide through in Wet mode and finish on a cool setting to set the style. A Hyperdymium motor drives a 13-blade impeller at up to 106,000 rpm, and glass bead thermistors check the air temperature up to 500 times a second.
Weight and guarantee
Amazon lists 820 g for this edition and a length of 33 cm, so it is heavier than a ghd Gold but lighter than the pink Airstrait's listing. Dyson gives a 2 year guarantee. Being a gift set, presentation is part of the appeal, though the listing does not describe any extra items in the box.
Airstrait against plate tools for fine hair
The Cloud Nine Original Iron starts at 100°C with heated plates, giving finer control on dry hair. The ghd Gold is the light, simple plate option at 185°C. If you want air plus plates, the Shark SilkiPro combines both, though with a higher listed weight.
What to expect from the finish
An air-straightened result looks like a sleek blow-dry, with movement rather than a flat, glassy finish. People who want poker-straight hair for an event may still prefer a plate straightener for that occasion.
Verdict
Pick the Plum Copper Airstrait if you have fine or fragile hair, start your routine with wet hair and want to avoid hot plates. If you prefer to style dry hair with gentle plates, the Cloud Nine Original Iron is the better match, and the ghd Gold suits anyone who wants a light, fixed-heat straightener.
