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.”
If you have ever visited a luxury spa or wellness company, you have probably run across far infrared heat a time or two. Without going into too much science, infrared heat is the same heat you feel when the sun kisses your cheeks and warms your body from the inside-out. Far infrared heat, in particular, has been used by medical and wellness professionals for years to treat a variety of conditions from muscle pain to even cancer.
As one of the hottest hair straighteners we have reviewed (temperature-wise…although it is pretty to look at, we have to admit…), the Solano Sleek Heat 450 Professional Flat Iron can reach temperatures of up to 450° F in as little as 60 seconds! This Solano hair straightener also features thin 1 inch plates, making it an ideal choice for anyone with short or medium length hair and the quick heat time ensures that even the most stubborn of curls can be tackled with a little extra heat. If you are looking or something a little larger though, it is also available with 1.54-inch plates too.

“I’m in ‘ahhh’ at how awesome of a straightener this is. If you ask me, it’s a lot better than the high-end brands. It leaves my hair silky-smooth and shiny. I absolutely love its features, and you can watch the heat meter rise as it’s heating up. To me, five stars is not enough to rate this product. It’s definitely worth the money. I’m in love with this straightener. Also, the lock on it I found to be a awesome bonus.”
EDITOR’S CHOICE: CHI has and always will be a powerhouse brand in the hair straightener industry, and the company’s new G2 Ceramic and Titanium Flat Iron is no exception! Packed with ceramic and titanium technology, this hair straightener was designed to give you silky, shiny styles without snags. We also love its easy-to-read, color-coded temperature settings, so you know the temperatures that you are using at any given time!
“I’ve owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! There really is no tugging at all on your hair — so smooth, and I was shocked that it truly heats up in 15 seconds, as advertised! It also does something magical to my hair: It adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. It has always been coarse, wavy, dry, and thick! This iron worked beautifully on my hair.”

The Bio Ionic worked well on all of our testers’ hair, but it’s best on drier hair with a medium thickness. We spritzed testers’ hair with some keratin smoothing treatment, but the Bio Ionic did a lot of the heavy lifting to make our hair feel softer. The tool gets hot, but not too hot to grip, and it excels at creating the silky volume you want without making your hair pin-straight and flat. One tester put it perfectly: “[The Bio Ionic] is the Rumplestiltskin of hair straighteners. It’s turning straw into gold.”
Curling irons, also known as curling tongs, create waves or curls in hair using a variety of different methods. There are many different types of modern curling irons, which can vary by diameter, material, and shape of barrel and the type of handle. The barrel's diameter can be anywhere from .5 in (1.3 cm) to 2 in (5.1 cm). Smaller barrels typically create spiral curls or ringlets, and larger barrels are used to give shape and volume to a hairstyle.
Most mid-grade and high-end hair straighteners come with plates that are 1” or 1.5”. If you are looking at one that is 2”, 2.5”, or even bigger, steer clear immediately. Not only does larger plates make it easier for you to accidentally over-iron (and seriously damage) your hair, but they also make it more difficult to get all of the way down to your roots. For anyone with type 3 or type 4 hair, trying to use a large-sized flat iron would be far more trouble than it’s worth.
Featuring the same 1.25-inch plates CHI users have loved for years, the new CHI G2 Ceramic and Titanium Flat Iron make it easier to style longer hair! If you’ve ever tried to use a non-professional hair straightener on your hair, then you know just how quickly the process can become a literal pain! From hand strain to sore wrists and arms, most hair straighteners stick to old adage of “beauty is pain.”
With a maximum temperature of 450° F, the BaByliss Pro Nano Titanium Straightening Iron can really pack a punch despite its otherwise small frame. One thing to note though: these heat settings are not pre-set like the CHI G2 hair straightener we also reviewed, and you will need to play around with them to find the right temperature for your hair. This shouldn’t be a problem if you have a Saturday afternoon or two to kill, but may not be ideal for users that are looking for a flat iron with pre-recorded settings.
At first, the Bio Ionic 10X Pro Styling Iron’s vibrating plates seemed gimmicky. But we were surprised at how effective they were when styling our hair. Our testers found the vibrating plates made straightening their hair go faster with virtually zero snagging. Engaging the vibration was also simple — click the power button and tap the plates together and you’re ready to go.

So far I like this straightener. I haven't figured out the curling part of it but will be watching some videos next for that. Other than that it does a good job of straightening hair. I have super thick hair with natural ringlets. It usually takes multiple passes to get my hair soft and smooth. This one does a good job b/c it closes properly down on the hair and doesn't leave my hair looking crimped. The hair also doesn't get caught under the blades and rip out of my head like my last straightener. I haven't used the $200 one that is comparable with this one but I am super picky and this is a good straightener!!


Celebrity hair stylist Priscilla Valles’s go-to straightner is the classic GHD 1-inch straightener. “I start in the nape and bring down small sections, one row at a time and I use a GHD flat Iron with a comb in the other hand,” says Valles. “I place the comb in front of the iron while ironing at the same time in a slow motion all the way down. Never stopping cause that will cause dents in the hair. At the end a dime size of ouai rose from top to bottom just to add some shine and control any fly aways!”
At $230, the Bio Ionic is pricier than any of our top picks. But you get what you pay for. You can truly do with your hair whatever you desire — straight or curled — in one pass. And, if you’re worried about it breaking a few years after purchase, the Bio Ionic comes with a five-year warranty. By investing in a better-quality tool up front, you won’t have to replace your flat iron every couple of years. Plus, the Bio Ionic goes on sale every now and then, so it’s worth keeping your eye out for deals.
If being limited to only a handful of temperature settings isn’t really your cup of tea, look no further than the BaByliss Pro Nano Titanium Straightening Iron! This lightweight flat iron features a whopping 50 heat settings for hair types of all shapes, styles, textures, and colors making it one of the most versatile hair straighteners on our list.
As an added bonus, titanium has also been found to resist rust, so your hair straightener will keep its out-of-the-box look for years to come. This is particularly important when you are making a long-term investment by purchasing a high-end or professional hair straightener. After all, you wouldn’t want your car or bathtub to start rusting after just a couple of uses and the beauty tools you use for your flowing hair should be no different!
