The MHD professional flat iron hair straightener is great for creating loose curls because it’s got smooth plates and negative ions that leave your hair soft and frizz-free. The 3D floating plate allows your hair to glide through without catching or breaking, and reviewers love it because it’s durable, reliable, and works on any type of hair — even the most stubborn and frizzy.
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.

This is a long review, but I want to be thorough, especially for the natural girls out there because I feel like reviews aren't specific enough for products for our hair! So far, it's definitely worth the $50. Here is a little info about myself and my hair, and my pros and cons are listed below: I am black, with natural, 4c hair and this straightener is one of the best I've had. I really wanted a steam straightener because I used to use the Chi religiously, but that severely damaged my hair. Now, I rarely use heat on my hair, and I don't plan on using this straightener more than once every 2 or 3 months. I've only used it once; I washed my hair, combed it out in the shower, put in moisturizer and heat protectant, blew it out, and then used the straightener.

We started with six flat irons but ultimately dropped two because they didn’t work well on any of our testers’ hair. The inexpensive, but highly rated HSI Professional Glider Ceramic Tourmaline Ionic Flat Iron was bulky and awkward. Testers said it felt like two pieces of plastic passing through their hair. We thought the NuMe Megastar Hair Straightener, a popular and more high-end tool, would be a clear contender for our list. However, testers said it snagged hard against their hair to the point of hurting. It was also difficult to hold closed when styling. Because both of these flat irons received such low ratings among our testers, we didn’t include them in our top picks.
Before placing your entire head under unnecessary heat conditions, try straightening a small section of your hair with what you believe is your ideal heat setting. Take notice of the way your hair reacts to this temperature, paying close attention to any fraying or singeing that may result. Smoking and that dreaded burnt hair smell are a sign that you may need to tone it down a bit to avoid permanent damage to your precious locks.

Hair straighteners come in a lot of different sizes, and that can make it more difficult to decide which one is right for you. By learning about the type of hair you have, the kind of style you want, and the amount of heat you need, you can also figure out what the best size iron for your hair is. It does make a difference for the sake of speed as well as precision. It sounds like a lot of work, but you can figure out what’s right for you by clicking here.

“I’ve owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! 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: It adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. It has always been coarse, wavy, dry, and thick! This iron worked beautifully on my hair.”


In addition to its sweet settings and versatility, this hair straightener is also super lightweight and features thin, 1-inch plates to save precious real estate on your bathroom counter or inside your vanity cabinet! The BaByliss Pro Nano Titanium Straightening Iron is ideal for anyone with a tiny bathroom (or multiple roommates!) and who wants the results of larger hair straighteners without the added weight or storage space.
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.”
The type of heat you use to style your hair makes a big difference in how healthy it will be. Our Xtava Pro-Satin Infrared Ceramic Flat Iron for Hair uses infrared heating technology, which heats hair from the inside out. Infrared technology is a game-changer for styling your hair because it allows heat to penetrate directly into the inner part of the hair strand, not just the outside layer. Infrared heating to the middle of the hair strand provides a more effective heat for styling and decreases damage to the outside of your hair. Infrared technology also stimulates negative ions in your hair that draw oils from the hair shaft to the surface; this helps lock in moisture and lock in your look, even in humid weather. Better heat = better hair health. Guess that’s not much of a secret after all, is it?
While it isn’t the fastest heating hair straightener we have reviewed, the CHI Air Expert Classic Tourmaline Ceramic Flat Iron warms up to temperature in just one minute! If one minute seems like too long for you to wait, try adding a bit of multitasking into your morning routine by taking advantage of this found time. If you are at a loss for what you can do in just one minute, check out this list for a little inspiration:
Eight embedded sensors regulate and evenly distribute the heat on this ceramic iron, minimizing damage and increasing shine and smoothness. With adjustable temperature settings that go as low as 140 degrees (the coolest we've ever seen), it's ideal for anyone with super fine hair, or to smooth out the tiny frizzies around your hairline. It also comes with a lifetime warranty, which is never a bad thing.
