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.

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.

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.”

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.

This lesser-known brand made a great impression when it was available on Amazon (you can now buy it at TerresaBeauty.com), where the majority of reviewers gave it five stars. "It allows my hair to glide so smoothly through the plates, never snagging it," says one shopper. "I can straighten or curl with this straightener and it works great," says another.

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.
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.
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.
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.
As one of the hottest hair straighteners we have reviewed (temperature-wise…although it is pretty to look at, we have to admit…), the Solano Sleek Heat 450 Professional Flat Iron can reach temperatures of up to 450° F in as little as 60 seconds! This Solano hair straightener also features thin 1 inch plates, making it an ideal choice for anyone with short or medium length hair and the quick heat time ensures that even the most stubborn of curls can be tackled with a little extra heat. If you are looking or something a little larger though, it is also available with 1.54-inch plates too.

While the BaByliss Pro Nano Titanium Straightening Iron is a great option for a beginner or someone on the go, we like to think of the Solano Sleek Heat 450 Professional Flat Iron as the no-nonsense, professional-grade alternative for anyone with short or medium length hair. This Solano professional hair straightener isn’t just for stylists or beauty bloggers though: the fast heat time and maximum heat temperatures make it an ideal choice for any aspiring stylist-to-be or anyone with stubborn shorter styles.
It has settings for different amounts of heat needed to straighten various types of hair. You should not use the highest setting unless your hair is very unruly with lost of natural oil. It is a well known fact that some straighteners can leave your hair hard and flat. This will never happen with model. Your hair will not get “cooked” even with daily use.

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.

Nor does it speak to those of us who work long hours at our job - who support our families and who struggle with issues like how to pay the bills or how to put the kids through college - who have limited time and energy for training - and who are more interested in how to train for lifelong strength and health than in how to gain 30 pounds of muscle in six weeks.
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.
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.
