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.”

Thankfully, we’ve learned a lot about hair care and preserving your hair’s natural integrity while styling. However, this wasn’t always the case. If you ever had a perm done in the 80’s or teased your hair to holy heaven in the 90’s, chances are pretty good that your hair has endured a bit of damage. The same can be said if you color your hair on a regular basis or recently went from your natural brunette color to a bright platinum blonde. No matter how the damage was caused, there are certain features you will want to shop for when selecting the ideal hair straightener for your course hair type:
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!
If you travel abroad often, you won't have to worry about ruining your investment, either, because the GHD Gold has universal voltage. It also features a generously long 9-foot cord with 360-degree rotation to prevent tangling. The automatic sleep mode shuts off the straightener if it hasn't been used in 30 minutes, so you'll have peace of mind if you forget to shut it off in your morning rush out the door. If something does go wrong, the GHD Gold comes with a 2-year manufacturer's warranty.

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’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!
If you are interested in adding the benefits of keratin use into other aspects of your hair care routine, treat yourself to a keratin-rich hair mask once per week! There are dozens of fantastic keratin masks on the market to choose from (and even in your local drugstore!), but we love Naat’s Brazilian Keratin Intensive Hair Mask (which you can buy here from Amazon) for a consistent shine every time!
When you see the perfect hairstyle, whether it's curly, wavy or straight, you want a professional styling tool that can help you try a little bit of everything. NuMe hair straighteners can do just that with a cascade of features that offers your hair just the right amount of TLC. Take your time when you style these tourmaline ceramic and professional titanium hair straighteners, to reveal your shiniest, healthiest looking mane yet. 
Eight micro-sensors with HeatBalance technology are used to evenly distribute heat, regulating the temperature so that you spend less time applying heat. As a result, it takes less time to straighten hair, preventing it from damage when styling. Additionally, the 1-inch plate width is wide enough for any hair length, yet narrow enough to style your bangs.
“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.”
So, when it comes to hair care, it is no surprise that the healing benefits of infrared technology would make their way into the industry sooner or later! The far infrared technology in the CHI Air Expert Classic Tourmaline Ceramic Flat Iron leaves your hair looking and feeling smoother and silkier than ever before, while helping to restore your strands to their naturally strong and beautiful thickness.

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.
Heat protectants contain ingredients that coat hair and slow down heat induction. Janine Jarman says, “Blow dry your hair properly; use a heat protectant product; and with the right iron, you should not have to make a bunch of passes to get the results you want.” We used TRESemmé Expert Selection Heat Protection Spray, Keratin Smooth. Most of our testers liked how it worked on their hair and felt a noticeable difference when using it. Our tester with kinky hair didn’t use the product because she knew it wouldn’t work on her hair. Instead, she recommends using an oil (like an Argan oil) or a hair grease to add moisture to the hair, which makes it easier to straighten.
There are many alternatives if you are looking for hair straighteners. You can use a tool such as a hair straightening or flat iron, you can try chemical perms and straighteners or you can attempt natural methods. Whether you're looking for permanent hair straightening or just want a treatment such as a serum, there are plenty of options for you to choose from at Walgreens.com.
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!
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.
For such a high-end flat iron, we were disappointed that the Babyliss doesn’t have a precise temperature display like the Bio Ionic. Our testers were confused by the settings, which had numbers going up to 50 vs. actual temperatures. The numbers represent a range, but you have to look through the instruction manual to figure out what that is. One tester summed it up perfectly: “I don’t want to read an instruction manual to use a hair straightener.”
It comes with the most advanced heating element in this industry. Using a digital display, you can adjust temperature from 280F to 450F. This means that you can use it to style fine or very fragile hair as well as very thick and coarse. This is the model that is often recommended for women that have hair that is hard to straighten and difficult to keep straight. So if lower heats do not work for you, use the highest setting, and get pin straight results, like glass.

If Gisele's mane meets your #hairgoals, consider this iron created by her stylist Harry Josh. The wider-than-usual 1.25 inch plates allow contact with a larger surface area in order to speed up styling time, and the quick-heating ceramic-titanium plates (it takes only 45 seconds to reach 400 degrees) abolish frizz and boost shine for model-worthy strands.

When taming coarse, wavy or curly hair, sometimes you need a little to kick it up a notch. That’s why we love that the CHI G2 Ceramic and Titanium Flat Iron can reach a maximum temperature of 475° F and heats up in under a minute! With this hair straightener, say goodbye to wasted time waiting for your tool to heat up, and get styled and out in the door!
I started this site after I made the decision to get a new hair straightener. I am not a novice with irons by any means, and I’ve had just about every kind imaginable except for some of the newest options. When I realized how far the industry had come in the last couple of years, I decided it was time to try something new. A good flat iron can last for years, as long as you look after it and make sure you buy one that’s robust enough to take what you put it through. By doing your homework up front, you can make sure you not only get the right straightener for your locks, but you don’t end up spending an inordinate amount of money on something that doesn’t work for you. Believe me, I’ve been there!
This feature is particularly beneficial for users with naturally wavy or curly hair, which can have a tendency to easily snag in hair styling tools. This floating design, combined with the heat sensor, also ensures that your gorgeous curls won’t become permanently damaged just because you decide to straighten things out a bit for an evening or two. After all, those curls are coveted by beauty pros the world over, and you never want to damage them just because of a styling trend!
