The Airstrait has the strangest rating profile of any premium hair tool in our data. On its main Amazon listing, 75 percent of owners give it five stars and describe it as the best thing they have bought for their hair. Another 13 percent give it one star, and their reviews read like a different product entirely: tangled sections, a tired arm, half a head still damp after thirty minutes. Almost nobody lands in the middle.
That split is the real story of this straightener, because both groups are describing the same machine used on different heads of hair. The Airstrait currently holds 4.2 stars across 286 reviews on Amazon, a low score by Dyson standards. The gap between the people it works for and the people it fails is so wide that the average stops being useful.
So this review is built around the gap. We pulled the current Amazon data for the Airstrait and for the three lower-priced tools buyers most often cross-shop against it, then mapped what owners report onto hair type. If you read nothing else, read the verdict below and the hair-type section after the table.
The Airstrait earns its premium tier for one specific buyer: someone with wavy, thick, or frizz-prone hair who wears it straight most days and currently spends an hour on a dryer plus flat iron. Owners in that group consistently report their styling time cut roughly in half, with hair that feels healthier than it did under hot plates. If your hair is already straight or fine, very tightly coiled, or you only straighten now and then, skip it. The cheaper tools below cover those cases for a fraction of the cost.
Why the Ratings Split Down the Middle
Read enough five-star Airstrait reviews and a pattern appears fast. The happiest owners have thick, wavy, or curly hair that they wear straight. Before the Airstrait, their routine was a blow dryer followed by a flat iron, often more than an hour end to end. For them the wet-to-dry trick is real: one owner with long, thick, naturally curly hair went from over an hour to about twenty minutes, and the finish survives a few days and humid weather without collapsing into frizz.
The one-star camp tells two different stories. The first is very thick or dense hair that forces tiny sections. When each section needs several passes to dry, the promised time savings evaporate, and a few owners describe giving up mid-head with a frizzy, tangled result. The second story is an expectations problem. People who wanted a flat iron experience, glassy and pin straight from the first pass, discover this is an air tool. It dries and aligns hair under tension rather than pressing it, and the finish is closer to a smooth blowout than to glass.
Two complaints cross both camps and are worth knowing upfront. At 2.2 pounds the Airstrait is heavy for a styler, and arms get tired during long sessions on long hair. The body also runs warm near the vents, so several owners wish a comb came in the box for guiding sections. Neither issue dominates, but neither is rare.
Which Hair Type Gets Which Result
- Already straight or fine hair. Skip it. The Airstrait solves a problem you do not have, and fine hair dries fast enough that a basic dryer with a brush gets you there. This group shows up in the disappointed reviews more than you would expect.
- Wavy or frizz-prone hair worn straight most days. The ideal owner, and the core of the five-star reviews. Wet to finished in one tool, less heat exposure than a daily flat iron, and a style that holds through humidity.
- Thick or curly hair. It works, with caveats. Plan on smaller sections and a clumsy first week while you learn the technique. Most owners in this group still save serious time against a dryer-plus-iron routine, which is why many of the strongest reviews come from exactly this hair.
- Coily or very tightly textured hair. The riskiest group. The recurring complaint is roots: airflow does not fully straighten the first inch near the scalp, and some owners finish with a flat iron anyway. If that compromise sounds annoying, it will not improve with practice.
The Airstrait is Dyson’s answer to a routine problem: drying and straightening as two separate jobs. It holds 4.2 stars across 286 reviews on Amazon. Instead of hot plates, it pushes precisely heated air through wet hair at a downward angle, drying and aligning each section in the same pass. Three wet-mode temperatures, a separate dry mode for touch-ups, and a boost setting cover the styling range.
The everyday details are better than the spec sheet suggests. The arms sense when hair is between them and quiet the airflow when it is not. The machine pauses itself after a few seconds of inactivity, and there is none of the singed smell of a flat iron session. Owners who switched from daily flat ironing are the most enthusiastic group, and the most repeated line in positive reviews is some version of the routine taking half the time it used to.
The honest catches: it is the heaviest tool in this comparison at 2.2 pounds, the body runs warm near the vents, and the first session is almost always worse than the third. Technique matters, sections need to be deliberate, and very dense or tightly coiled hair will fight it at the roots.
Skip this if your hair is already mostly straight, if you straighten less than a few times a week, or if you expect the glassy finish of hot plates. This machine sells time, and you need to be spending enough of it to buy some back.

Before spending premium money, be honest about whether you need straightening or just smoothing, because the REVLON One-Step is the most popular answer to the second problem. It carries 4.6 stars across 351,811 reviews, the largest review base of any styling tool in this comparison by a huge margin.
It is a hot-air brush, not a straightener. You rough-dry damp hair and brush through it while the airflow finishes the job, and what comes out is a smooth, rounded blowout with volume at the roots. For wavy hair that just needs taming, that result covers most days, and the technique takes one session to learn, not a week of practice.
What it will not do is make textured hair actually straight. Curl comes back, edges stay soft, and on thick or coily hair it is a smoothing tool at best. It is also pure hot air on the hair surface, so heat exposure is closer to a traditional dryer than to the Airstrait’s regulated airflow.
Skip this if you genuinely wear your hair straight. Buy it if most of your straightener use was really about frizz and polish, which is true for more buyers than will admit it.
REVLON One-Step Volumizer
The Remington Wet2Straight is proof the wet-to-dry idea did not start at a premium tier. It rates 4.6 stars across 4,911 reviews and goes from damp hair to a straight finish in one tool, using vented hot plates that release steam as they press.
The mechanism is the opposite philosophy of the Airstrait. Instead of avoiding plate contact, it embraces it and vents the moisture out, with salon-level heat up to 450 degrees Fahrenheit available when you want it. The result is closer to a classic flat-iron finish, flatter and more polished than an airflow tool produces, and owners rate the outcome highly for the money.
The trade-off is heat. Pressing hot plates onto damp hair several times a week is exactly the exposure the Airstrait was designed to avoid, and longtime daily users tend to graduate away from it. As an occasional tool, though, the math is hard to argue with: most of the one-tool convenience for roughly a tenth of the spend.
Skip this if you straighten daily and care about long-term hair health. Buy it if you want the wet-to-dry shortcut a few times a month and a pin-straight result matters more to you than gentle treatment.
Remington Wet2Straight
The TYMO Ring answers a different question: what keeps hair straight on day two and three? It is a heated straightening comb with 4.4 stars across 83,146 reviews, built for dry hair, fast mornings, and touch-ups rather than full wet-to-finish sessions.
Owners use it the way the category intends, brushing through dry or mostly dry hair in a few minutes to refresh a style, tame regrowth at the roots, or knock out morning frizz. The comb format is faster and harder to mess up than a flat iron for that job, and it reaches scalp-adjacent sections that bigger tools handle awkwardly.
It is not a wet-to-dry tool and it is not a deep straightener for very coily textures, where owners report it smooths more than it straightens. Think of it as the maintenance half of a routine: whatever does the heavy lifting on wash day, this keeps the result alive between washes.
Skip this if you want one tool for the entire wash-day routine. Buy it if your real frustration is the daily five-minute fight, or as the in-between companion to any of the tools above.

The Trade-Off Nobody Prices In
Every tool in this comparison is really selling you minutes, and that is the honest way to decide between them. The Airstrait’s premium only makes sense against a routine that currently costs you an hour, several days a week. Cut that in half and the machine buys hours back every week. But if your styling routine is already twenty minutes, there is no time left to save, and the cheaper tools cover the same ground.
There is also a patience tax the glowing reviews skip past. Nearly every detailed owner report, positive or negative, agrees the first session is clumsy: sections too big, angles wrong, results underwhelming. The owners who pushed through describe a skill that clicks within a week. The owners who judged it on night one wrote the angriest reviews. Whichever tool you pick, give the technique three sessions before you decide, and keep the return window in mind while you do.
How to Decide Before You Spend
Start by counting your straightening sessions in a normal week, honestly. Daily or near-daily straightening of wavy, thick, or curly hair is the only pattern that justifies the Airstrait’s tier, and it is exactly the pattern its happiest owners share. Twice a month does not get there, no matter how nice the machine is.
Then place your hair on the spectrum from the section above. Wavy and frizz-prone hair worn straight is the sweet spot. Tightly coiled hair should assume root touch-ups will still happen and weigh whether the partial win is worth it.
Finally, work the ladder from the bottom. If smoothing is the real goal, the REVLON One-Step probably ends your search. If you want wet-to-dry occasionally, the Remington does it at a budget tier. If day-two maintenance is the pain, the TYMO covers it. The Airstrait is the right buy only when none of those cheaper answers fit, and for the right head of hair it genuinely is the upgrade its five-star owners describe.
Does the Dyson Airstrait work on curly or coily hair?
It straightens curly hair, but owners with very dense or tightly coiled textures report needing smaller sections and more passes, and some still finish their roots with a flat iron. The tighter the curl pattern, the smaller the time savings. Wavy to loosely curly hair sees the best results in owner reviews.
Is the Airstrait worth it for short hair?
Usually not. Short hair already dries and styles quickly, so the time savings that justify the premium mostly disappear. It still works on short styles, and the lighter sessions reduce the weight complaint, but the value case is much weaker than for long, thick hair.
Does the Airstrait damage hair or cause hair loss?
It uses regulated heated airflow instead of hot plates, and in wet-to-dry mode Dyson positions it as styling without heat damage. Owners who switched from daily flat ironing often say their hair feels healthier over time. Review data cannot show a styling tool causing or preventing hair loss; persistent shedding is a question for a dermatologist, not a straightener.
Should I buy the Airstrait or the Airwrap?
They do different jobs. The Airwrap is a multi-styler built around curls, waves, and volume, while the Airstrait does one thing: straight finishes from wet hair. If you wear your hair straight most days, the Airstrait is the more direct tool. If you switch between styles, the Airwrap covers more ground.
Can you use the Airstrait on dry hair?
Yes. It has a dedicated dry mode with two temperature settings plus a boost option for touch-ups and refreshing day-two style. Most owners buy it for the wet-to-dry routine, though. If dry-hair touch-ups are your main use, a heated brush like the TYMO Ring handles that for far less.
How is the Airstrait different from a regular flat iron?
A flat iron presses dry hair between hot plates. The Airstrait pushes heated air through wet hair under tension, drying and aligning it in the same pass. The finish is a soft, blowout-like straight rather than the glassy, pin-straight result of plates, which is why some owners still pass a flat iron over their front pieces.
