Dyson Airstrait vs ghd Duet Style

How each one is built

The Dyson Airstrait has no hot plates. Its listing describes air that is precisely heated and projected evenly through the section as you style, with sensing that drops to low airflow when hair is not between the arms. Dyson's no-heat-damage claim applies when used wet to dry.

The ghd Duet Style combines air and plates. ghd calls it air-fusion technology that dries and straightens at the same time. It has advanced floating plates with an ultra-glass coating, plus root drying vents that direct airflow outward at a lower temperature for the roots.

Spec table from the listings

Weight is a common question for these tools. Neither listing states it, so it is marked not confirmed.

Settings and dry-hair use

The Duet's Shine Shot mode is the practical difference. On dry hair it switches off the air and works as a ghd styler at 365F. That means one tool can dry and straighten after a wash, then smooth a frizzy section the next day. Our ghd temperature explainer covers why ghd sticks to 365F.

The Airstrait listing does not detail heat settings. Dyson publishes more on its own site; our Airstrait temperature settings page covers what Dyson states. If you need dry-hair touch-ups often, check those details before you buy.

Finish and hair contact

Because the Duet uses plates as well as air, expect a result closer to a flat iron, especially in Shine Shot mode. The Airstrait never presses hair between hot plates, so its finish generally has more softness and movement.

If your goal is the sleekest possible finish on thick or curly hair, a plate tool tends to win. Our Airstrait vs flat iron comparison covers that trade-off in more depth.

Price and value

At listed prices the Airstrait costs $289 more. Both replace a separate dryer for straight styles. The Duet adds a dry-hair plate mode at a much lower price. The Airstrait's case rests on its plate-free design and Dyson's airflow system. Read is the Dyson Airstrait worth it if you are weighing that premium.

Using a wet-to-dry straightener well

Both tools work best with a similar routine. Start with hair that has been towel-dried so it is damp rather than dripping, detangle fully, and work in sections small enough for the arms to cover. Keep the tool moving at a steady pace from root to end. Dyson and ghd both publish step-by-step instructions, and our how to use the Dyson Airstrait guide covers the Dyson routine in detail.

Very thick or long hair takes longer with any wet-to-dry tool because there is simply more water to remove. If that describes you, plan for a longer first session while you learn the section size that works.

Who each one suits

The ghd Duet Style suits people who want one tool for wash days and touch-up days. It dries and straightens from wet, then works as a fixed-temperature plate styler in Shine Shot mode on dry hair. It is also the obvious pick if you trust ghd's 365F approach and want to spend about $210 rather than about $500.

The Dyson Airstrait suits people who specifically want straightening with no hot plates touching the hair, and who mostly style straight after washing. Its sensing, which drops to low airflow when hair is not between the arms, is a comfort feature during long sessions. If you are not sure air straightening will suit your texture, start with our how to use the Dyson Airstrait guide to see what the routine involves.

Either way, use the tool as each maker directs. The Airstrait's damage claim is tied to wet-to-dry mode, and the Duet's Shine Shot mode is for dry hair only, per its listing.
