These Are Officially The Top Flat Irons And Best Hair Straighteners To Purchase In 2021

There are few hair tools on the market more versatile than a trusty flat iron. The things can curl, wave, and straighten your hair to perfection. Not only that, but they also work on literally any hair texture—it's just a matter of finding the right one. Lucky for you, the internet has no shortage of options when it comes to straightening tools. But it would be helpful to know which one is the best for your specific hair type, the difference between ceramic, titanium, and tourmaline, and—oh yeah—which one is best. That's why we're here to help you find the crème de la crème of whatever your heart desires. Ahead, we break down the best flat irons on the world wide web and give you the 411 on what makes them so great.

WHAT'S THE DIFFERENCE BETWEEN CERAMIC, TITANIUM, AND TOURMALINE? 

So what's the difference between the three types of flat irons, and why does it actually matter? To put it simply, achieving the pin-straight hair of your dreams requires you to use a flat iron that's suited for your specific hair type and needs. Ceramic irons work best on easy-to-straighten hair—think textures that range from fine to wavy. Titanium works best on coarse and curly hair, and it's the most common type of straightener found in a stylist's tool kit. Lastly, tourmaline is the type of flat iron you'll want to use if your hair is already damaged or you're doing all you can to avoid damage. Additionally, these tools are great for neutralizing ions that cause static and frizz. 

HOW DO I CHOOSE THE BEST STRAIGHTENER FOR MY HAIR? 

When it comes to the shape of your flat iron, you'll want to keep your texture in mind. If you're attempting to transform your unruly curls into the glass hair you see all over Instagram, you'll want to use a thinner or more narrow straightener. If your hair is straight for the most part but still requires a few touch-ups, you'll want to go for a wider shape. Lastly, if you're looking for a tool that can handle small sections or shorter hair, you'll want to use something mini, like a travel-sized flat iron. 

The next thing we recommend putting some thought into is how you intend to use your iron when it comes to styling. If you're going for tight ribbon curls, you'll want to search for a flat iron with a rounder shape. If beachy waves are in your look book, search for something with a wider, flatter shape that you can easily twist and turn throughout your hair. 

HOW TO GET THE MOST OUT OF YOUR HAIR TOOL

Reaching your straightener's fullest potential starts with a great base. Before you embark on your straightening journey, make sure your hair is completely dry, has been prepped with a heat protectant, and is detangled. Next, section your hair into small pieces, beginning to straighten at the root and gliding the flat iron down to the end. To be frank, straightening your hair or using any sort of heat will always lead to damage. But you can avoid a whole lot of it by using your heat tool on the lowest setting. Trust us—it'll still work just as well.
