Hair straighteners come in a lot of different sizes, and that can make it more difficult to decide which one is right for you. By learning about the type of hair you have, the kind of style you want, and the amount of heat you need, you can also figure out what the best size iron for your hair is. It does make a difference for the sake of speed as well as precision. It sounds like a lot of work, but you can figure out what’s right for you by clicking here.
If you’re looking for an affordable mid-grade hair straightener that offers tremendous value, you can’t go wrong with the HSI Professional Digital Ceramic Flat Iron with Tourmaline. With a quick heat-up, digital LCD temperature control, and solid ceramic plates infused with tourmaline, you can straighten type 3 hair – and some type 4 hair – with ease.

For those with thick hair, the idea of "quick styling" often feels like an impossible dream. It's usually easier to use the "throw it up and go" technique to get out the door in time. However, straight, sleek hair doesn't have to be a luxury reserved for those with fine hair, especially when you have a styling tool designed to tackle even the thickest, curliest hair like the Xtava Pro.
The more temperature control options you have, the more control you'll have over the heat you'll be applying to your hair. Keep in mind, any type of heat styling can be damaging to your strands, so you want to take care not to use too much high heat, especially if you're styling daily. Flat irons that have lower temperature options that start around 250 degrees Fahrenheit are ideal for those with thin, damage-prone hair. If you do have thick hair, higher heat settings can help straighten those curls. To help prevent damage, you should start with lower heat first, and then only increase as needed. Keep in mind, anything above 400 degrees has the potential to damage your hair. Even those with coarse, curly hair should stay within the 350-400 degree range to be safe.
Our two testers with kinky and thick hair loved the Chi Air Expert Classic Tourmaline Ceramic Flat Iron. In fact, it was each of their top picks, with the Bio Ionic coming in second. The Chi Air reaches 410 degrees F, which is definitely hot enough for thicker and curlier hair types. The speed at which the tool worked was surprising considering the kinkiness and thickness of both testers’ hair. One tester with long, curly hair had to leave early for an event and needed to finish styling. The Chi Air moved through her hair quickly, giving her time to spare. And, even at 410 degrees, our testers didn’t feel like their hair was being fried or that the heat burned their heads. In fact, they complimented how soft it made their hair feel and how comfortable it was to use, unlike the NuMe Megastar which snagged a lot or the HSI Professional Glider which felt hot against their scalps. As one tester said, “Chi is killing it.”
“I bought the HSI titanium tourmaline ionic flat iron and I was so impressed with it. It glides so smoothly down the hair without any tugs! The digital display screen lets me adjust the temperature without any problems, it heats up fast, and I love that it comes with a pretty purple pouch, glove, and argan-oil serum. I also own the digital HSI ceramic ionic flat iron from 2013, and it’s still going strong, but I do like the titanium iron better, and I see myself using for it for years to come. It leaves my hair shiny and soft!”

We started with six flat irons but ultimately dropped two because they didn’t work well on any of our testers’ hair. The inexpensive, but highly rated HSI Professional Glider Ceramic Tourmaline Ionic Flat Iron was bulky and awkward. Testers said it felt like two pieces of plastic passing through their hair. We thought the NuMe Megastar Hair Straightener, a popular and more high-end tool, would be a clear contender for our list. However, testers said it snagged hard against their hair to the point of hurting. It was also difficult to hold closed when styling. Because both of these flat irons received such low ratings among our testers, we didn’t include them in our top picks.
While it isn’t the fastest heating hair straightener we have reviewed, the CHI Air Expert Classic Tourmaline Ceramic Flat Iron warms up to temperature in just one minute! If one minute seems like too long for you to wait, try adding a bit of multitasking into your morning routine by taking advantage of this found time. If you are at a loss for what you can do in just one minute, check out this list for a little inspiration:

This styling iron has 1-inch plates, allowing it to do more than just straighten. It can also curl, flip, and be used to add volume if your hair tends to fall flat. It heats up in under 30 seconds so you can start styling almost right away, and there are a wide range of temperature settings from 250 degrees to 460 degrees Fahrenheit. While the high-temperature options make this straightener ideal for other hair types, too, if you do have fine hair you'll want to keep this in the lower temperature range.
Unlike the Bio Ionic’s handy digital temperature control, the Chi Air uses a small dial on the side of the tool that’s harder to read. The dial’s placement makes it not only more difficult to get an accurate reading, but also more prone to being hit by your hand and switching to a new temperature. That being said, most of our testers didn’t mind this minor inconvenience since they don’t expect to change the tool’s temperature often.
4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
Coming in at a close second, the CHI G2 Ceramic and Titanium Flat Iron is our second editor’s choice as the best hair straightener on the market today – featuring fool-proof and color-coded temperatures for easy straightening or who just wants to protect their luscious locks. We also love the digital display that is featured on the CHI G2 model along with its combination ceramic and titanium design for optimal shine!

Available with either ceramic plates (good for all hair types) or titanium ones (choice for curly, thick, and coarse textures), this innovative styler features touch sensor technology that lowers the heat when it's not being used, then automatically brings it back up to temp as soon as it's touched. Translation: No more waiting for your iron to heat up in between passes. Use it for smooth and sleek styles, or take advantage of the round brush-esque attachments to create more of a bouncy blowout effect.
