This feature is particularly beneficial for users with naturally wavy or curly hair, which can have a tendency to easily snag in hair styling tools. This floating design, combined with the heat sensor, also ensures that your gorgeous curls won’t become permanently damaged just because you decide to straighten things out a bit for an evening or two. After all, those curls are coveted by beauty pros the world over, and you never want to damage them just because of a styling trend!
The plate material you choose can also make a big difference on your style results. Ceramic, titanium, and tourmaline are the most common terms you'll come across. Ceramic plates hold heat well and provide even heat distribution, preventing any hot spots on the plates can cause damage. Ceramic is especially effective for fine hair that can be especially vulnerable to heat damage. While many hair straighteners have ceramic coated plates, plates made entirely from this material are more effective, as this coating can wear off over time. Tourmaline is a gemstone, but when crushed and used to coat the plates of a hair straightener, it has properties and results similar to ceramic plates.
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!
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.
At first, the Bio Ionic 10X Pro Styling Iron’s vibrating plates seemed gimmicky. But we were surprised at how effective they were when styling our hair. Our testers found the vibrating plates made straightening their hair go faster with virtually zero snagging. Engaging the vibration was also simple — click the power button and tap the plates together and you’re ready to go.
Unlike the Bio Ionic’s handy digital temperature control, the Chi Air uses a small dial on the side of the tool that’s harder to read. The dial’s placement makes it not only more difficult to get an accurate reading, but also more prone to being hit by your hand and switching to a new temperature. That being said, most of our testers didn’t mind this minor inconvenience since they don’t expect to change the tool’s temperature often.
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.

In the end you want to make sure that your hair is protected no matter what hair straightening treatment or tools you choose. Many hair straighteners are for daily discipline and upkeep. There are lotions, sprays, balms, serums and cremes to help you tame wavy or curly hair, control frizz or protect from humidity. Several hair straightener creams offer protection against damage from hair dryers and hot irons. Look for the hair products that will protect your hair and keep it smooth, shiny and silky.


The ability to create bouncy curls or waves with a flat iron (we know, it seems counter-intuitive!) is a biggie in the beauty industry and merits a bit more discussion. If you’re totally lost and there aren’t enough video tutorials on the planet to explain this weird yet awesome process, don’t worry! Just follow along with our step-by-step guide and you will be curling with the best of them in no time!

The Babyliss gets hot quickly and moves through hair fast. This is thanks to its thin, lightweight design and the fact that it stays consistently hot. Our testers were amazed that it passed through their hair so quickly and left it smooth without feeling damaged or fried. Plus, when being styled by someone else, our testers said it didn’t snag their hair.


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.
This feature is particularly helpful if you have textured hair with waves or curls, which can become damaged so easily by heated styling tools. That said, it is not clear which heat setting is ideal for users with thick or somewhat straight hair. This may make this slightly more difficult if you are using a flat iron for curling purposes or if you need to straighten an especially thick head of hair each day! However, we are confident that a little tinkering is all it takes to find the perfect heat setting for these different hair types and styles, so you can rest assured that this hair straightener can still meet all your hair styling needs!
Just because you were blessed with a head of naturally straight hair, doesn’t mean hair straighteners aren’t for you! Hair straighteners are a great way to style the split ends that are all too common with straight hair types and can also give your hair a natural-looking curve for added volume! When shopping for the best hair straightener for your naturally straight hair, you will want to look for the following:
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?
An upgrade from their since discontinued Eclipse Styler, you won't be tempted to heat this flatiron up to 450 degrees, because the temperature dial is always stuck on one number: 365 (the ideal heat to mold hair without frying it, according to the scientists at GHD). Underneath each of those 365-degree plates are three fancy sensors that measure the density of the hair in the iron so that it can maintain consistent heat regardless of the chunk of hair you grab. The result? Silky, shiny hair with zero frizz.
