But, surprisingly, finding the best flat iron doesn’t have to be a nightmare (yes, really). First, know that the more efficiently your straightener works, the better it is for the overall health of your hair, which meant it’s time to throw away your gunk-covered flat iron from high school. Second, it’s 2019, and straighteners have come a loooong way in the last decade, so even though, sure, there are certain flat irons that are better for certain hair types (more on that below), you can kinda pick and choose whichever straightener seems best, and you really can’t go wrong.
FHI’s rounded edge allows you to easily curl or add waves without much effort. It’s almost as small as a travel flat iron, and I love that it straightens even the poofiest sections with just a single pass. But don’t just take my word for it, listen to Beyoncé (via InStyle): “I’m crazy about it! I can’t live without my flatiron! It takes me about an hour to do my hair, and the only time I don’t is when I’m on vacation.” (Picture younger Beyoncé, doing her own hair on vacation).
Beachwaver Co. has reached cult-level status for its super easy-to-use Beachwaver, yes, but this styling iron from the brand is equally as notable. The beauty of it is the fact that you can achieve multiple looks with it. Use as is for a sleek, straight look or apply the black Coast Pro attachments (that are shaped like a round brush) and glide the iron down each hair section, rolling your wrist under towards the ends to create the illusion of a professional blowout.
Thanks to the tourmaline ceramic plates, this iron “glides through my hair, never grabbing or pulling it,” writes one reviewer. Others point out that this tourmaline ceramic plate “works way better on fine hair than other types,” not burning thin strands even at high temperatures. Or, as one reviewer writes, “It’s well made, it doesn’t snag my fine hair and because of the heat control settings, doesn’t burn it either. Yay for not having breakage!”
Most of the hair straighteners we reviewed heat up in under a minute, but the Cloud Nine Original Flat Iron has to be one of the fastest on the market! In as little as 20 seconds, this hair straightener transforms from cool to hot, hot, hot! With this model, there is no need to wait around for your hair straightener to warm up, which means you spend less time getting ready in the morning and more time getting on with your day.
For undereye bags and inflammation, caffeine, peptides and hyaluronic acid can be soothing, Mattioli says. “Dark circles can be due to visible veins or actual discoloration common in darker skin tones,” she says. “Look for brightening ingredients like vitamin C, kojic acid and niacinamide.” Insider tip: Steer clear of strong retinols (which can sting and create redness) and fragrance, to avoid any eye irritation.
Though it looks high tech with an LCD screen, this budget-friendly straightener has impressed Amazon reviewers everywhere. "I have very thick curly/wavy hair and in a matter of 45 minutes my hair was the straightest I’ve ever been able to get it by doing my hair on my own," wrote one reviewer from Florida, who said her straight hair managed to endure the state's humid climate.
Sephora’s best-selling hair straightener and flat iron list is dominated by styling tools from big hitter GHD. The crème de la crème on the beauty retailer’s list is GHD’s Platinum+ Professional Performance 1” Styler. The flat iron operates at 365-degrees Fahrenheit, which the brand considers “the optimum styling temperature for even healthier hair,” has a 20-second heat-up time, and a heat-resistant plate guard to protect your furniture and other surfaces. While the price point is definitely on the higher side, GHD’s hair straightener uses predictive technology that adapts to your hair’s individual texture and needs, promising you a unique — and worth it — hair-styling experience.
