According to the numbers, the HSI Professional truly is a high-quality product that is well-deserving of the attention it's been given.

Aside from ionic and infrared technologies the Bio Ionic Onepass Straightening Iron has something that is entirely new to me: silicon covered plates. They get the hair more in order when you’re straightening, save you a lot of time and reduce the amount of heat that you need. This one is great for African American hair, but I already selected the xtava Pro Satin for that because it’s more affordable.
Titanium is a lightweight metal that heats up very quickly and can hold high heat at a consistent temperature. This material is ideal for those who have thick, curly, or natural hair that can be more difficult to straighten. Since it's lighter than ceramic, it also makes for a lighter hair straightener overall, which means less arm strain as you're taming your mane. As someone who has very thick hair, I can attest — Any feature that can make styling easier and faster is a plus.

Though it looks high tech with an LCD screen, this budget-friendly straightener has impressed Amazon reviewers everywhere. "I have very thick curly/wavy hair and in a matter of 45 minutes my hair was the straightest I’ve ever been able to get it by doing my hair on my own," wrote one reviewer from Florida, who said her straight hair managed to endure the state's humid climate.


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.
I tried to break everything up on the chart by category so it’s easier to narrow things down, but you have to keep in mind there is a ton of overlap in styling tools. You can have large ceramic tourmaline and small titanium steam as well as just about a thousand other options. The point is, although my table is here for those of you who already have an idea of what you want, there is a small chance you might end up looking at something with a few extra bells and whistles because there is so much overlap. If you’re not sure what different kinds of irons there are, head over to my buying guide so you can get that all sorted out before you start reading the reviews.

“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.”
This straightener is a miracle worker! African-American women with extremely coarse hair consider this tool a godsend. Thanks to 5-inch extended plates, faster and more efficient straightening is finally possible, especially for those mornings when you’re in a rush. If you want a hair tool that can help you with styling details, this BaByliss PRO is a very good solution.

The BaByliss Pro Nano Titanium Straightening Iron really is the Baskin Robins of hair straighteners, making it the perfect choice for anyone that wants to straighten their hair quickly. Whether you have naturally short hair and opt for extensions on occasion or you just chopped off your do’ into a new pixie cut, you will have a hard time not finding the perfect heat setting for your hair so many choices!


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.
Now that you know what the Xtava Pro is capable of, it's worth running through the features that make those results possible. Along with the solid ceramic plates for even heating, there are 10 temperature settings to choose from for optimal styling control. The temperatures are shown on an easy to read digital display and range from 265 degrees to 445 degrees Fahrenheit.
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.”
Straighteners work because they have flat plates that get hot and touch together on either side of your hair. By doing that, they put heat through your hair follicles, trap in moisture and take out frizz. The plates on a flat iron can be made of several different materials, and they’re good for different uses. The best iron for you varies depending on the type of hair you have, the type of styling you want to do, and the amount of heat your hair needs.
The Chi Air is similar to other Chi tools and has that iconic sleek design with gold plates. However, one feature our testers believe makes the Chi Air stand out against the Chi Elite and others is that it’s so lightweight. True to its name, the tool is lighter than other flat irons which makes it easier to manage when styling. One tester believed the light design even made it snag less when passing over hair.
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.
“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.”

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!
The ½ inch plates allow the BaBylissPro Mini to get close to the scalp, so it will straighten hair from root to tip. It's lightweight and compact at 6 inches long, so it will fit easily in a purse or carry-on bag with no hassle. It comes with a heat resistant travel pouch for storage so you can pack up and go at a moment's notice before or after straightening your hair.
Once you get over the sticker shock, you'll see just how revolutionary this tool is. It's not a traditional flat iron by any means, but one of the attachments called the "firm smoothing brush" can be used to straighten and smooth frizz in coarse, thick hair. Best part? It works on damp hair, so you're cutting down on the time it takes to get ready as well.

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.
It becomes extremely hot – up to 392 degrees Fahrenheit, and it holds that heat until you shut it off. Because of this, you can straighten any type of hair with Chi, including very thick and coarse tresses. So if you have such hair, this iron could be your best option. It is not only designed to straighten but also to curl hair. Thanks to its ergonomic design, you won’t strain the hands and wrists during use.

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!”
