Best Investment: Dyson Airstrait

Why It's Worth It: If you're a fan of the Dyson Corrale, just wait until you get your hands on an Airstrait. This wet-to-straight flat iron takes damp strands and transforms them into a silky-smooth waterfall of flyaway and frizz-free hair in minutes. The beauty of this tool is that it relies on the velocity of hot air instead of heated plates, so its highest temperature is a gentle 285 degrees Fahrenheit. Sure, it's a splurge, but its unique, hair-health-first design makes it worth the cash.

Tester Feedback: "I found the dryer function useful and intuitive," says commerce producer Sarah Hoffmann. "It's really nice not having to hold a brush in one hand and a hair dryer in the other for the 30-plus minutes it takes for my hair to dry," she says. "The wide clamp is great for covering large sections of hair all at once, but I definitely needed multiple passes to add shine and smoothness to my curly hair."

If you're unsure about your settings, the Mane website offers a handy guide on which heat setting to use depending on your hair type and styling goals, but generally, if you have fine hair or fragile hair, lower temperatures are better.

Tester Feedback: In addition to straightening her whole head of hair, contributing commerce writer Annie Blackman loves using the Mane The Three Way Multi-Use Flat Iron for post-blowout touch-ups. "The narrow shape of this flatiron is perfect for touching up sections of hair as I reach the end of the day's styling journey." She makes sure to brush through sections as she glides the tool along her locks (and uses clips to keep things organized). "To make my naturally wavy hair more approachable, I use Mane's Ready or Knot Detangling Brush, which works like a dream to work through any lingering kinks."

Frequently Asked Questions

You may be wary of using high heat on your hair, but hair straighteners are perfectly safe for your strands when used correctly. "The key is to use them on dry hair and ideally as a finishing tool. I typically recommend smoothing with a round brush before straightening. Always apply a heat protectant before styling to shield your strands from high temperatures," says hairstylist and founder of Trademark Beauty, Joseph Maine. “Also, it's important to keep the flatiron clean to ensure it heats evenly and doesn't snag your hair.”

"Use a haircare product that's marketed as a heat protectant before straightening your hair. In general, I don't recommend using oils because they can burn, along with your hair, when applied right before using a flat iron," warns NYC-based hairstylist Devin Toth. "Don't go over the same section of hair over and over again. It's better to go over it once, slowly. People tend to have more damage in their face-framing area of hair because they hit it with the iron too many times to get them just right," he adds.

Another key to straightening safely is to be mindful of the temperature of your flat iron. The optimal temperature to avoid burning is 365 degrees Fahrenheit.

"Flatirons work by using heated plates to temporarily alter the structure of your hair, making it straight. When you apply the heated plates to your hair, the heat breaks down the hydrogen bonds in the hair's cortex, causing it to straighten," says Maine. "Once your hair cools down or gets wet, these bonds reform, and your hair goes back to its natural state," Maine adds that varying materials like ceramic, titanium, or tourmaline have different effects on the heat distribution and speed of the straightening process.

Picking a hair straightener is a personal choice and largely depends on your hair type and styling desires. "For fine or damaged hair, look for a flat iron with adjustable heat settings to prevent overheating—ceramic plates are great for even heat distribution without getting too hot," Maine tells Allure. He adds that if your hair is on the thicker, or coarser side, a hair straightener with titanium plates is ideal because they "can handle higher heat and manage frizz more effectively."

Toth explains that plate size and shape are key to selecting a hair straightener. "The wider the plate, the straighter the hair will look. So if you like to really bend and bevel the ends of your hair then choose a more narrow plate," says Toth. Maine echos Toth, explaining that a "wider plate can straighten more hair at a time, which is useful for thicker hair, while a narrower plate is better for short hair, detailed styling like bangs, or achieving specialized styles like flat iron waves or curls.

According to Maine, you should also consider the type of plate edges featured on a hair straightener before making your purchase. "If the plates of the flat iron are slightly protruding out of the iron and the edges of the plates are beveled, then you will be able to effortlessly make curls with this tool," he states. "If the plates are not protruding with beveled edges, then the iron is mainly designed for straightening hair."

We always enlist a range of testers for any review, but hair-care products and tools are another story. While some can be used across different hair textures, lengths, curl patterns, thicknesses, colors (natural and unnatural), and concerns, many are created with specific consumers and their needs in mind. When reviewing tools, we also take into account testers’ experience levels. For instance, an innovative new blow-dryer may feature industry-leading technology, but if the only people who find it intuitive to use are professional hairstylists, we have to consider this when determining whether it is worthy of a recommendation.

For our review of the best hair straighteners, we enlisted the help of multiple editors, writers, contributors, and hair stylists with varying hair types and desired styling outcomes, and whether one product was tested across multiple hair types. Testers considered performance across three primary categories: efficacy, safety, ease of use, and value. For more on what's involved in our reporting, check out our complete reviews process and methodology page.

A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.

After all, can we really say a skin-care product is the "best" for people over 50 if the only testers we’ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We're proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
