These two tools straighten hair in very different ways. The GHD Chronos is a flat iron with heated plates, used on dry hair. The Dyson Airstrait has no plates. It uses airflow to dry and straighten damp hair in one step.
Quick pick: the GHD Chronos for the flattest, glossiest finish and a much lower price. The Dyson Airstrait if you want to skip the blow-dry and keep hot plates off your hair.

How They Work
GHD Chronos: a 1-inch flat iron that heats to GHD’s set styling temperature of 365°F (185°C). GHD’s motion-responsive technology is designed to keep the plates at that temperature as you move through each section. You use it on fully dry hair.
Dyson Airstrait: two arms blow high-pressure air down the hair as you pull the tool through. It has wet and dry modes, so you can start on damp, towel-dried hair.
Finish
The Chronos gives a flatter, glossier result. It’s what you want for poker-straight hair. The Airstrait gives smooth hair with more movement, closer to a good blow-dry.
Speed
The Airstrait saves time if you’d otherwise blow-dry first. The Chronos is quick on dry hair, but you need to dry your hair before you start.
Hair Health
The Airstrait never touches the hair with a heated plate, which is its main appeal for fragile or bleached hair. The Chronos works at a single, controlled temperature rather than the very high settings some irons offer. Either way, use a heat protectant.

FAQs
Is the Dyson Airstrait better than GHD?
It’s different. Dyson is gentler and saves a step. GHD gives a flatter finish for less money.
Which causes less heat damage?
The Airstrait, because no heated plate touches the hair. The Chronos limits itself to one controlled temperature, which helps.
Can I use the GHD Chronos on wet hair?
No. Flat irons are for dry hair only.
Which is better for thick hair?
The Chronos usually straightens thick hair more completely. The Airstrait needs smaller sections.
