Fine or thinning hair can easily become damaged under too much heat, so cooler temperatures (i.e., those under 300° F) are ideal for these hair types. If you have very curly, course, or thick hair, then higher temperatures upwards of 400° F may be more suitable to your needs. With the ISA Professional Titanium Flat Iron, you can cool it down to 265° F if need be and also crank it up to a whopping 450° F for textured styled.
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.”
4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
With well over 25,000 reviews, the HSI Professional Ceramic Tourmaline Ionic Flat Iron is one of the best straightening irons you can get, but because of its thin build and rounded plates, you can also use it to curl your hair. It’s got solid ceramic plates to reduce damage, evenly heat hair, and promote shine, and if you’re a traveler, it’s got a dual voltage that can be used anywhere in the world.
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.
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.
The floating plates are contoured with smooth edges, so you won't have to worry about your hair snagging as you're styling. If you have thicker hair, you may want to consider the 2-inch plate option, which will cover more surface area and help you style your hair more quickly. However, if you'd rather have the versatility of being able to curl and flip your hair as well as straighten it, we'd recommend the classic 1-inch plate.

It is important to consider what options are important to you when selecting a hair straightener. You must select a hair iron with a heat setting that fits your needs. If you have fine hair, a lower heat setting may be sufficient. However, thick coarse hair may require a higher heat setting to achieve your desired look. Plate size should also be considered. A flat iron with small plates might be best for shorter hair, while a flat iron with larger plates might be best for longer hair. Some hair straighteners have features such as temperature readouts and rollers that might be important to your needs.
For some people, automatic shutoff is a critical feature since forgetting to unplug your flat iron could lead to a fire. However, others aren’t fans of auto shutoff since that means their flat irons could turn off while they’re still styling their hair. If this is the case for you, we recommend investing in a timed switch. That way, you can program the switch to turn off at a specific time and your flat iron will shut off as well.
The Chi Elite Flat Iron has all the features Chi flat irons are known for. Like the Chi Air, it comes with a one-hour shut off and temperature dial to ensure you’re getting the correct heat. It also worked across all hair types and was specifically good on kinky, curly and thick hair. One of our testers even said it “work[ed] better than the Babyliss” and that styling her own hair with it was “not as uncomfortable.”
Not sure which temperature setting is right for your hair? We recommend starting slow and building up to higher heat settings gradually. Not only will you be able to perfectly identify the optimal heat setting for your hair, but you will also avoid overheating. After all, very few of us actually need upwards of 400° F to see the salon results we’ve always wanted!

Derek Yuen, the man responsible for Cole Sprouse's grown-up new look, recommends the GHD Platinum Professional Performance iron. The flat iron is consistently and evenly heated at 365 degrees, which is safer and less damaging on the strands. “The beveled edges also allow for infinite styling possibilities, not just just for straightening hair,” says Yeun.


You wage an endless battle against frizz so your hair straightener is one of the most important tools in your bathroom. When it is time to upgrade to a more professional model or replace an old straightener that has seen better days, check out eBay. Easy search functions make it simple for you to find a ceramic hair straightener that fits your style and your budget. Many people prefer ceramic, titanium, or tourmaline plates, and some straighteners come with interchangeable plates in different materials or designs to create crimped or wavy looks. Pick up a mini hair straightener that is perfect for traveling, and you always look good no matter where you go. Many reliable sellers on eBay offer a vast inventory of straighteners in different colors, styles, and types. All you have to do is find the hair straightener that suits you and maybe pick up a spare, just in case.
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.
Sure, the drugstore flat iron you used on its highest setting back in the day was clunky and had a tendency to fry your hair if you glanced away for more than a second, and okay fine, your mom probably told you that you looked a little “emo” from time to time. Luckily, those days are long gone and hair straighteners have truly come a long way since the days of The Jersey Shore.
This durable KIPOZI flat iron can be set anywhere between 170 and 450 degrees to suit any kind of thickness or texture, and its curved plate design makes it great for giving your hair some texture. The Nano-Titanium plates heat up quickly and lock in moisture, so hair looks hydrated, healthy, and sleek. It’s also got a compatible voltage for anywhere in the world.
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!
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:

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.

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.
