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.
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.
This iron is one the coolest tool I’ve ever used. It is a beautiful looking straightener with very high technology. With 50% more power and wider plates (1.5″), the T3 SinglePass X is specifically designed to straighten hard-to-manage hair, such as long, thick or coarse hair. Most importantly, it is designed to do the job fast – it straightens in a single glide!

I've owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! A lot of research was done before I made the decision to purchase this one, and I feel like it paid off; my previous straightener was 4 years old, so it was about time. I received this new one today before I got home for my lunch break, so I had to go ahead and bust it in ;) There really is no tugging at all on your hair - so smooth, and I was shocked that it truly heats up in 15 seconds, as advertised! It also does something magical to my hair, like it adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. I am a Caucasian, but my hair has always been coarse, wavy, dry and thick! This iron worked beautifully on my hair. 10/10 would recommend! If it doesn't work the same after a few months, I'll be sure to update my review. As of today, I'm very happy! :)


Size matters. With plates too big or too small, you’ll have to make multiple passes. This exposes your hair to high heat longer and increases the risk that you’ll do damage. According to Janine Jarman, owner and operator of acclaimed Hollywood salon Hairroin, a 1-inch-wide plate will do for most people, and if you want to use your iron for anything other than straightening, like creating curls or waves, you’ll need a 1-inch plate; anything larger won’t make the waves or curls tight enough. She also pointed out length is important too. “You need plates to be at least 3 inches long, or close to it, so you’re not spending a ton of time with small sections.”
Creative director of GLAMSQUAD Giovanni Vaccaro prefers this flat iron by Sedu. "The ceramic plates are really key to maintain the integrity and healthiness of the hair," he says. To get expertly straight hair, Vaccaro recommends using a boar-bristle brush to help mediate frizz, and that "the follow through is key" when moving the iron and comb completely from roots to tips.

When you feel like it’s time for straight, shiny locks, we’ve got your back. Our flat irons are so well-designed and powerful they can straighten even the curliest of hair. Our selection of hair straighteners also come in a variety of sizes, colors and shapes, and some even include thermal bags or travel containers so the flat iron is protected. Many of our irons also include a warranty to guarantee that the electronic components are functional for years to come. Depending on how long or short your hair is, or the type of styles you seek, you will need to select a style that best suits your styling needs. For instance, a 1.5-inch iron works best on medium to long hair, while 1-inch irons are typically made for shorter hair.
This BaBylissPRO porcelain ceramic straightening iron is made with porcelain ceramic, which distributes far-infrared heat evenly across the strands. Not only is it gentler and more healthy for your hair, but it can handle wide sections of hair at once because of its long barrel. The shape is rounded and sleek, so it’s ideal for curling, and it won’t catch or knot while you’re curling.
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.
