20 Best Flat Irons for Extremely Straight Hair

best flat irons 1280

A good flat iron is one of those styling tools that can turn a “meh” hair day into a great one. Even second-day hair (or third...or fourth?) can get an instant refresh with a few passes of a straightner and some dry shampoo.

The best flat iron is speedy, sleek-looking and won’t totally damage or destroy your tresses. Each of the following on this list -- choose from ceramic, tourmaline and ionic technology -- is a favorite among stylish celebs and pro stylists (as well as us mere mortals). And each will deliver serious shine and style to your frizzy, wavy, curly hair and natural hair.

Just a few swipes with one of these hair tools will have you looking and feeling like you just emerged from the salon when you haven't even left the house.

So bypass the keratin treatment, turn up the heat and shop the best flat irons on the market, below. (And not to nag, but don't forget the heat protectant.)

ET Style's Picks for the Best Flat Irons:

The Ceramic Flat Styling Iron from Harry Josh (Gisele Bundchen's hair stylist) straightens and smooths hair, leaving it super-shiny and silky. At 1.25 inches the ceramic plates are a bit wider than most flat irons but the plates are also curved with a nice grip, so you can pull hair through without it slipping or holding it too tightly to create that weird flat iron kink.


A true classic, this versatile straightener from Chi gives you straight and sleek strands with minimal damage, thanks to its ceramic plates. It also helps tame frizzy hair and static to keep hair looking silky and smooth. No wonder it's considered the best flat iron by many beauty lovers.


Long hair and even super-thick hair are no match for this sunny yellow straightener from blowout salon Drybar. It also zaps frizz and its temperature control function protects your hair from heat damage. Plus, the rounded edges mean you can also use it to create waves and curls -- no curling iron required, if you’ve got the hair styling tool skills! 


For those who aren’t keen on running hot plates directly over their hair, this heated styling brush (a relative of the buzzy Revlon One-Step) is a great alternative. This heat styling tool features ceramic coated bristles that glide seamlessly through the hair, straightening your strands as you brush. With extra-long bristles and a special ion generator that delivers a constant stream of frizz-reducing negative ions, it allows you to straighten out kinks and curls with less damage. And good news, especially for ladies with short hair: Its extra-long bristles can get right to the root of your hair -- something that can be tricky with conventional irons.


Attention folks! This is the flat iron that Beyonce uses! Beyonce told Instyle about her love for this flat iron “I’m crazy about it! I can’t live without my flat iron! It takes me about an hour to do my hair, and the only time I don’t is when I’m on vacation.” This FHI Heat Platform Tourmaline Ceramic Pro Styler is a compact flat iron whose rounded edges allows you to easily add waves or curls flawlessly.


Dyson's  Corrale Hair Straightener, which uses innovative flexing plates that allow for lower heat and thus less heat damage. Over on the brand's Instagram Story highlights, founder James Dyson explains that the flat iron's plates corral the hair into an oval section (that's where it got its name!), holding it together and easing tension. And according to celebrity hairstylist Jen Atkin, you can use it with the cord or go cord-free when you're on the move. We also love that it has an idle mode; after not being used for five minutes, it automatically shuts off.


The Babyliss Pro Nano Titanium Ultra-Thin Straightening Iron is a mouthful -- maybe because it can do so many things. With 50 heat settings, it's suitable for all hair types from thick hair to fine hair, and its 5-inch plates allow for faster straightening. Plus, it's slim and lightweight enough to travel with easily. Needless to say, this tool is a solid beauty investment.


This Remington ceramic flat iron is proof that you don't need to spend a ton to look like you just walked out of a blow-dry bar. The ceramic plates on this flat iron hair straightener are infused with crushed pearls, which will give you that "Did she just get a blowout?" look.


Conair's Infiniti Pro Rainbow Titanium 1'' Flat Iron goes after stubborn curly hair to gives you straighter results thanks to the rainbow titanium plates which offer superior heat conductivity and the True Ceramic heater heats up in 15 seconds and maintains heat level and has a heat for every hair type.


This best-selling straightening iron leaves your hair so shiny that friends might start seeing their reflection in your strands. The 1-inch ceramic plates maintain an even temperature and seal your hair cuticle for extra smoothness -- and as the name suggests, you only need to use it once on each section of hair. If you are planning to straighten your hair on the go, let us introduce you to the SinglePass travel straightener, an absolutely adorable mini flat iron.

Hot tip: GHD stands for “good hair day,” and let’s just say that this professional flat iron straightener lives up to its name. It spreads heat evenly over the plates at an optimal temperature -- 365°F, if you're curious -- to prevent breakage, protect color and deliver a super-straight look in seconds. 


This bright pink, patterned straightener is more than just a pretty hair tool to show off on your vanity. Each nano-diamond-infused ceramic tourmaline plate -- along with silver and other mineral powders -- create a type of heat called far-infrared. This method is unique because it prevents damaged hair by actually locking in moisture to keep each hair strand soft and supple. FYI, Amika recommends using these heat guidelines for its adjustable heat setting, according to your hair type: Fine, thin hair should stay below 360°F; normal, medium and wavy hair can go between 360°F and 380°F; and thick, coarse and curly hair can crank it up between 380°F and 450°F.
