Try first flat ironing your hair from the roots on the lowest temperature on your flat iron, and straighten your hair normally. When you are comfortable with the way that you are straightening your hair, then you can start straightening your hair with the temperature that you would normally straighten your hair, but don't forget to use a heat protection spray so that you don"t damage your hair.
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.)
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.
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!

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.
Brant Mayfield, who styles everyone from Diane von Furstenberg to Nicole Scherzinger, favors this glossy white flat iron. "It has digital single pass technology, which helps for smoothness and contains an eternal microchip that maintains an even temperature," he says. The angled edges and ceramic plates will keep your hair smooth and without kinks.
The digital interface accurately displays the fully adjustable temperature setting from 170 degrees to 450 degrees Fahrenheit, providing optimal performance for any hair type. The floating plates with curved edges continuously adjust the tension and angle of the plates to avoid snagging your hair so that you have full flexibility when creating sleek, wavy or curly styles.
While temperature control is typically a good thing to have in a hair straightener, it can also result in hair damage if you're keeping the temperature too high. The GHD Gold eliminates the chance of any user error, operating at an even 365 degrees Fahrenheit. This is the optimal temperature for most hair types, getting you smooth results without damaging your hair. The gold coated ceramic plates heat up quickly and maintain an even temperature, eliminating the chance for any hair damaging hot spots as well.
“I’m a licensed hairdresser and I’ve used many hair straighteners, including Chi and Paul Mitchell. They work, but my hair is so thick that it takes me at least 30 to 40 minutes to properly smooth my hair. This is the absolute best hair straightener I have ever used. It straightened my hair in ten minutes (no joke). I’m extremely pleased and shocked. Looking to purchase a second one to have on hand for the future.”
The glider plus is designed to protect your hair with integrated heat balance micro processors that continuously monitor the exact temperature across the surface of the plates and automatically adjust the temperature for evenly distributed heat. That means fewer passes are needed for silky results, while protecting your precious hair from over heat exposure.

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.
Those with fine hair can keep the straightener at a lower temperature, while those with thick hair can increase the temperature to ensure they'll walk away with the same smooth results. No matter your hair type, the floating plate design and the curved edges of the plates themselves prevent any snagging or damage so your hair will glide through smoothly.

I'm 52-years old, and I've been training since I was 9-years old. That means that I know plenty about strength training, and plenty about the challenges faced by an older lifter. At age 52, I know and understand things I didn't know and understand at age 30 - or even at age 40 -- or age 45. GRAY HAIR AND BLACK IRON is the end-result of more than 52 years of living - and more than 43 years of physical training. It contains a lifetime of training experience - experience that you can use RIGHT NOW to train better, smarter and more efficiently than ever before.
If you’re a professional or more experienced with a flat iron, then it’s worth considering the Babyliss Pro Nano Titanium-Plated Ultra-Thin Straightening Iron. We were impressed with how well it worked across all hair types. It’s one of two top picks that straightened all of our testers’ hair in one pass (the other one that could do this was the Chi Air). And, like the Bio Ionic, the Babyliss leaves hair feeling smooth and voluminous.

“Infrared is so beneficial being that the wavelengths are longer and can penetrate deeper into the cuticle heating the hair from the inside out, keeping your hair's own natural moisture, leaving the hair smooth (and) shiny and keeping it extremely healthy, versus other conventional styling tools that actually pull moisture out of the hair, leaving the hair dry, brittle, dull and damaged,” said hair expert and stylist Gina Rivera.
Anyone with naturally curly knows that the trick to keeping your curls looking their finest is all about moisture. Whether you’re hoping to sport a straightened style for an evening or two, or just to polish your existing curls, a great hair straightener can help you get the look you’ve always wanted without causing permanent damage to your precious curls! When shopping for the perfect hair straightener for your curly hair, you’ll want to keep the following in mind:
My daughter is natural with 4b/4c. Her hair is very thick plus she is tender-headed (sensitive to anyone doing her hair). I have purchased numerous of flat irons in the past but none has stood apart from the Furiden stream iron. I was quite surprised at the outcome. It was definitely worth the wait. I love the fact that it less damaging to her natural hair and it does the job well, even my friends were shocked with the results. Oh, the comb like on the flat iron was an awesome ideal. I strongly recommend this flat iron to all my natural sisters. My only regret that I did not take before and after pictures of her hair.
Consider this the perfect flat iron for full hair. "It is great for thicker textures because it distributes heat evenly, allowing for less passes through the hair," explains stylist Lacy Redway. The plates "make it easier to straighten or curl longer hair lengths." Redway was responsible for  Tessa Thompson’s sleek ‘do on her past ELLE cover, so you know it’s top-notch.
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.

Ceramic and electrical straighteners were introduced later, allowing adjustment of heat settings and straightener size. A ceramic hair straightener brush was patented in 2013.[6] Sharon Rabi released the first straightening brush in 2015 under the DAFNI brand name. The ceramic straightening brush has a larger surface area than a traditional flat iron.
The plates of the HSI Professional are made of solid ceramic that is infused with tourmaline. The combination allows for consistent temperature and gives hair a smooth finish. The wide range of heat settings, starting at 140 degrees Fahrenheit and going up to 450 degrees Fahrenheit, gives you more control over styling and makes this an ideal straightener for multiple hair types.

This is a long review, but I want to be thorough, especially for the natural girls out there because I feel like reviews aren't specific enough for products for our hair! So far, it's definitely worth the $50. Here is a little info about myself and my hair, and my pros and cons are listed below: I am black, with natural, 4c hair and this straightener is one of the best I've had. I really wanted a steam straightener because I used to use the Chi religiously, but that severely damaged my hair. Now, I rarely use heat on my hair, and I don't plan on using this straightener more than once every 2 or 3 months. I've only used it once; I washed my hair, combed it out in the shower, put in moisturizer and heat protectant, blew it out, and then used the straightener.
If you’re a hair straightening novice, you may be a little intimidated during the first few times you use your new flat iron. These feelings are totally normal (after all, you are putting 300+ degrees of heat right near your scalp!), but there is no need to worry. All you have to do is follow these simple steps and you will have the gorgeous, flowing hair you’ve always dreamt of in no time!
Seemingly small details like cord length can make all the difference in the effectiveness of a beauty tool. A longer cord length is desirable here, giving you more freedom and versatility depending on the power outlet situation in your home or your hotel if you're traveling. A cord with 360 swivel capabilities is also a plus. You'll be moving your hair straightener all around your head as you style, and a rotating cord will keep it from getting tangled.
If you're looking for style versatility, NuMe hair straighteners are designed to do it all and allow for some creativity too. Each authentically crafted NuMe hair straightener offers only the highest quality materials, including 100 percent pure tourmaline ceramic, stone ceramic, and titanium plates. With beveled edges and floating plate design, you'll never snag your locks or be confined to one style. Create fashionable curls, crimped looks, relaxed beach waves and so much more. Unlock the possibilities with your NuMe hair straightener. 

Sadly, the plates in the LumaBella Keratin Duel Touch Hair Straightener won’t begin to magically levitate on your bathroom sink! BUT they do float in the frame! They are specially engineered to deliver a consistent heat with a smooth glide, and their design enables a flexible grip on the straightener, giving you great results no matter how you hold it. Even better, it won’t tug or pull like so many others on the market. The result is pain-free styling in a fraction of the time!
