In dry mode, the Airstrait makes use of decrease airflow with temperature settings of 250°F, 285°F, and “enhance,” which fits as much as 320°F and is really helpful just for touch-ups. When working with moist hair, increased airflow is required and you may select from three completely different warmth settings that begin a lot decrease: 175°F, 230°F, and 285°F.

How precisely does it straighten with out heated plates?

This query has been floating across the Attract workplace. The Airstrait actually isn’t the primary wet-to-dry instrument we’ve tried — earlier this 12 months, GHD launched a reasonably nice one, the Duet Fashion. However the distinction between the Airstrait and wet-to-dry instruments that got here earlier than is, as a substitute of conventional scorching plates, this system options unheated stress bars alongside the highest aspect of the arms to clamp the hair when straightening. These bars act as plates, Craft explains, making use of stress for a clean end, however put much less strain on the hair. And, yet another time: They’re unheated. It’s solely high-velocity scorching air — popping out of 1.5 mm gaps in every arm of the instrument and projected down at a 45-degree angle — that straightens the hair because it dries it.

Does the “no harm” declare take a look at?

“No scorching plates. No warmth harm.” That’s the declare Dyson makes with the Airstrait. As of press time, the model was not in a position to present info on the testing it had carried out to again this declare. However Evans from TRI Princeton thinks it is a affordable one (noting that he has not examined the instrument himself). “At heats this low, this instrument is unlikely to trigger harm to even moist hair,” he says. “When you go above 375°F, that’s when a scorching instrument turns into damaging to the hair.” Bear in mind, the Airstrait’s highest warmth setting is 285°F, with a touchup enhance setting at 320°F (to be used on dry hair).  It is value noting that the GHD Duet Fashion additionally makes a no harm declare — it does have scorching plates, however they solely attain 248°F, with airflow going as much as 302°F.

To stop the frizz, dullness, and cut up ends related to warmth harm, “a tool used on moist hair must take away the water with out creating excessive warmth or steam,” Joshua Zeichner, MD, a board-certified dermatologist and director of beauty and scientific analysis in dermatology at Mount Sinai Hospital in New York Metropolis, beforehand advised Attract. A lot of the Attract editors who examined the Airstrait say they seen minimal steam through the styling course of.

How I examined:

All of this sounded nice to me, however it was time to place the system to the check. I began the trial with my regular wash-day routine, utilizing my present favourite shampoo and conditioner, the OGX Thick & Full + Biotin & Collagen Shampoo & Conditioner, following up with a K18 therapy and a few warmth protectant from Tresemmé as a result of, whereas the Airstrait field says “no warmth harm,” this instrument would nonetheless be directing a variety of scorching air at my hair.
