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.”
We loved the Bio Ionic’s user-friendly design. Two of our favorite features are its bright digital temperature control and the instructions stamped directly onto the tool. It also feels natural in the hand, and its matte finish provides a slight grippiness, but doesn’t pull at the hair when styling. Plus, the tool sports a uniquely shaped plate that’s curved at the tip and makes it really easy to get close to the scalp. One tester who is new to using flat irons said the Bio Ionic felt intuitive and even encouraged her to try harder styles, like creating curls and waves.
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.

We don’t know too many people that are using their hair straighteners vertically, but there must be a few since ISA has made a point of clarifying that this model is intended only to be used horizontally, i.e., perpendicular to your hair. According to the manufacturer, using the hair straightener horizontally reduces hair pulling for a more comfortable experience. This may be particularly important to you if your hair tends to knot easily or you have unruly curls and texture.

But if you ARE one of the rare breed - one of the Iron Game elite - one of the small number of men and women who have been lifting hard and heavy for as long as you can remember -- then do yourself a big favor - hit the ORDER button and reserve your copy of GRAY HAIR AND BLACK IRON right now! Because the sooner you're holding it in your hands, the sooner you'll be on your way to the best and most effective workouts that you or any other older lifter ever imagined. 

This iron is one the coolest tool I’ve ever used. It is a beautiful looking straightener with very high technology. With 50% more power and wider plates (1.5″), the T3 SinglePass X is specifically designed to straighten hard-to-manage hair, such as long, thick or coarse hair. Most importantly, it is designed to do the job fast – it straightens in a single glide!

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.

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!
If you’ve ever used a CHI hair straightener before, then you’re probably pretty well acquainted with the turn dial temperature control of models’ past. While this dial design made it easy to switch on your hair straightener each morning (even before you have had your morning coffee!), it also made it all too easy to accidentally change the temperature during use.

This mini straightener is perfect for my bangs. I also used it to make some longer strands wavy by pulling it down at an angle. I bought it for travel abroad in Denmark since it has the dual voltage, but have only used it in the US so far. It heats up fast and makes my hair super smooth. And the free sample of conditioner smells soooo good and made my hair super soft!

The question is, does it live up to all the hype? There are more than 30,000 reviews on Amazon, 70% of these reviews give a 5-star rating, and 14% give a 4-star rating. According to the numbers, the HSI Professional truly is a high-quality product that is well-deserving of the attention it's been given. Buyers love how quickly the HSI Professional heats up, what it does for their hair, and how easy it is to use— even on short hair.


Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about the best curling irons, hair dryers, and even a certain curling iron used on the Victoria’s Secret Angels, here, we’re going deep on the best flat irons and hair straighteners on Amazon. (Note that reviews have been edited for length and clarity.)

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!
“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!”

The Hair Glider also features automatic safety shut off after 1 hour of inactivity. Dual Voltage make is perfet for travel. Pure Black Magic worry free! Order today and get your hair perfectly straight, shiny and manageable!

This flat iron is amazing! I have natural curly hair, and I live where it's humid a good majority of the year. This flat iron is good enough to keep my hair straight for a few days. That's with using products like hairspray, dry shampoo etc. I've been using this for about a month, 3-4 days a week, and haven't noticed any heat damage. That's always a plus. I'd say this was a good buy!
This is an absolute MUST HAVE for anyone with natural black hair. We talked earlier about how dangerous low-end flat irons can be for anyone with type 3 or type 4 hair, and this is precisely why. If you fit into those hair types, any straightener without an adjustable temperature control is likely to be way too hot for your hair to handle – especially for long-term use.
One of the Babyliss’ major drawbacks, and why we only recommend this flat iron for experienced users, is the outside gets hotter than any of our other picks. Hot to the point that it was too hot to hold. One tester said she was “afraid to accidentally touch the top of it.” Others said they could feel the heat against their scalps. At first, another tester said she didn’t mind the heat. This was moments before she burned the top of her hand when it merely grazed the side of the tool.

“This flat iron is amazing! It is so small, it almost looks like a flat iron for a doll. Don’t let the size fool you. I have medium-thick, naturally curly hair, and this iron had no problem getting all of my hair straight. If you are used to a flat iron, you should have no problem using this. This is the best flat iron for traveling, the gym, or stashing in your desk at work. I would highly recommend this flat iron.”
The CHI brand has long been one of the most popular for hair straighteners and flat irons, and for good reason – their products work well and they work quickly. The CHI Original Pro 1” Ceramic Tourmaline Flat Iron is no different. Thanks to its durable build, quality craftsmanship, and leading tourmaline-infused ceramic plates, this is the last hair straightener that you will need to buy for a long time.
There is a slide at the base which holds the device from opening all the way (easier for storing) but if you slide the piece it allows the flat iron to open all the way. The instructions inside the box don't explain this part, so at first I thought it didn't open very far, but once I figured this out, it became a breeze to use. Speaking of the instructions, they are listed in English, Spanish, French, and German. (I think... I don't speak/read all of those languages, but I believe that's correct.)
“This is a badass flat iron. Here’s the skinny: The moment you turn it on, it has a ‘Fragile, Damaged, Healthy’ setting, and it also auto-locks the buttons to keep what temperature you want while doing your hair. It comes with a professional bag for traveling with it. This flat iron is ‘pinky in the air while drinking your tea’ fancy. It is the Ferrari of flat irons, for a girl on a budget wanting a new flat iron. And for my fellow sistas: It works amazingly on African-American hair.”
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.”

That’s what is so great about hair straighteners: these devices can give you salon-worthy curls or celebrity-inspired straight hair that can change just as easily as your mood if you’d like! So, the next time you find yourself wishing for something you don’t naturally have, try using your hair straightener to bring out the best of your natural beauty. Who knows, you just might love a change!


All this is so well documented and that's great! I have poker straight hair but I crave for curls and more volume all the time. I also use flat iron to curl my hair but the difference is - I'm NOT able to do this good job. But it is also damaging my hair so I'm trying some more ways to curl my hair without heat which I read here http://thelifesquare.com/how-to-curl-your-hair-85...And I must say one of them worked for me really well.
One of the biggest problems you will face when using a heated hair styling tool is overheating. We’ve all been there: you’re casually straightening your hair when a particularly funny scene comes up on the show you have playing in the background. After a solid minute or two of laughter, you realize (in utter horror!) that your poor hair has been sandwiched in between a couple of hot plates the entire time.
