If you are unsure what exactly your hair type is (or if it has changed over the years, which happens more often than you’d think!), check out this incredible overview by the hair professionals at Redken! Don’t stress if you have combination hair (i.e., fine and curly or thin and straight) either; we recommend choosing a hair straightener based on your biggest hair complaint and focusing on that problem first. So, if your curls are driving your nuts, you will want to select a hair straightener with higher temperatures, thin hair needs moisture, etc. You’ll find that your entire hair type can usually benefit from the extra TLC!
It contains tri-zone® technology, which works quickly and effectively to straighten, curl and style without compromising the health of your hair. The technology uses three sensors in each plate to ensure the optimum temperature for styling hair is consistently maintained across the entire plate from root to tip, reducing breakage and improving shine.
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.
Perfect for straightening, curling or waving, this straightener features high-gloss titanium floating plates for a smooth glide, and advanced ceramic heaters to ensure fast and even heat distribution. Utilizing Ion Boost Technology, the straighteners deliver active conditioning ions to help hair look smoother and shinier, and are housed in strong, lightweight steel with curved edges to keep the plates aligned and allow you to create effortless curls and flicks. Versatile and easy to use, this amazing tool is the perfect choice for anyone who needs a tool that can do it all!
Gisele uses this flatiron. Need we say more? OK, maybe a little bit: From the same celebrity hairstylist whose blow-dryer launch nearly broke the Internet,this green-plated flatiron is equally as buzzworthy. It has plates that are larger than most other irons (meaning fewer passes) and rounded edges that prevent snagging or pulling. And because it shuts off automatically after an hour, it's ideal for those of us who constantly forget to unplug our flatiron before running out the door.
Twist And Curl – The awesome folks at Good Housekeeping couldn’t have put it better than this: curling your hair with a flat iron is like curling ribbon with a pair of scissors. To do this, simply clamp your hair straightener around a piece of hair as you normally would when straightening, except flip the entire tool, so your hair is now wrapped around one of the plates. Holding the tip of your hair for support, simply glide the straightener down the entire length of hair and just like magic, you’ve made a curl!
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:

The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.

“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!”

Negative ions have been a longtime fan favorite in the hair care industry, and it is no surprise that this same technology would appear in our top picks for the best hair straightener.

We’ve all heard the saying that the grass is always greener on the other side, and our hair types tend to follow the same old adage. If you were born with a head full of beautiful curls, you probably spent your childhood longing for straight hair; if you were born with bone straight hair, then you’ve probably spent more hours than you’d care to admit with a throbbing curler-induced headache. No matter how hard we may try to love the hair we’re born with; the truth is that most of us wish there were something else perched on top of our heads from time to time.
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.
This Amazon reviewer dubbed it the "perfect travel tool" that straightens their hair just as effectively as a normal sized hair straightener and they like that it automatically changes voltage so you don't have to worry about doing so manually. Reviewer Lynn B. writes on Ulta that she loves how quickly it heats up, and how she can easily pack it away right after use thanks to the heat-resistant carrying case it comes with.
BUYER BEWARE: I bought this from Amazon LLC, but the product would NOT register as authentic on ghd's site. I tried the hologram code and date code multiple times, but the site wouldn't verify the numbers. Also there was no country of manufacture listed on the unit, the box or the booklet. The styler looked great and was packaged well. Did the unit and stickers look authentic? Yes in every way. But the ghd site states: "fake ghd products are virtually impossible to spot." I called ghd, and a rep said sometimes legit numbers aren't accepted by the site (?!) - and told me that sometimes fake numbers go through. So in the end not sure what good the checker does. The rep did add that "Amazon is not an authorized dealer for ghd products." And the rep echoed what another reviewer said, "the only way to authenticate a styler not bought from us or an authorized dealer is to send it in to the warehouse." That's too much trouble for anyone. Is the one I bought legit? I just can't tell for sure. I'm not taking the risk. Returning it to Amazon.
