With well over 25,000 reviews, the HSI Professional Ceramic Tourmaline Ionic Flat Iron is one of the best straightening irons you can get, but because of its thin build and rounded plates, you can also use it to curl your hair. It’s got solid ceramic plates to reduce damage, evenly heat hair, and promote shine, and if you’re a traveler, it’s got a dual voltage that can be used anywhere in the world.
The more temperature control options you have, the more control you'll have over the heat you'll be applying to your hair. Keep in mind, any type of heat styling can be damaging to your strands, so you want to take care not to use too much high heat, especially if you're styling daily. Flat irons that have lower temperature options that start around 250 degrees Fahrenheit are ideal for those with thin, damage-prone hair. If you do have thick hair, higher heat settings can help straighten those curls. To help prevent damage, you should start with lower heat first, and then only increase as needed. Keep in mind, anything above 400 degrees has the potential to damage your hair. Even those with coarse, curly hair should stay within the 350-400 degree range to be safe.

A lot of hair straighteners will boast that their nano-ceramic like this is a good thing. In reality, this means that they’re made up of a cheap filler material (that will not heat as evenly or remain as durable as true ceramic) which is coated with a thing outer ceramic layer. If you want a flat iron that’s safe for natural hair, make sure you go 100% ceramic, or better yet, solid ceramic infused with tourmaline or titanium.
A lot of people don’t know there are tons of ways you can style your hair with a flat iron, and this actually might help you decide what size iron to get. You can curl, wave, straighten, add body, twist and more – just with a flat iron! Your straightener is so versatile you can skip most other styling tools and save money by investing in one that will do all of this for you. I walk you through different options for styling with your flat iron so you get the hairdo you want.
That is just one of the reasons that hair straighteners are such a wonderful tool to keep in your beauty arsenal; not only does this nifty little device give you movie star-quality straight hair when you want it (sorry blow out bars), but it can even create the same curls as those confusing barrel-ended curling irons! So, clean out your cabinet under the sink and make room for that makeup you’ve been eyeing or the perfume your husband forgot to buy you for Valentine’s Day last year, because a professional-grade hair straightener can literally replace all of your existing heated hair care tools!
Most reviewers on Ulta love the GHD Gold, praising how quickly it heats up, how it makes their hair feel, and how long this tool has lasted them. Some reviewers did feel that it was too expensive and didn't like the lack of control they had over the temperature setting. While those with very fine hair may find the 365-degree setting too hot, the lack of different settings, in this case, is to help prevent hair damage. The price is steeper than some, but it's also a straightener that's built to last, which helps justify the price.

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.
It is packed with the most advanced technology to give you shinier, smoother results that lasts longer. The one-inch wide heating plates are made of high quality, durable ceramic that provides an ultra smooth surface so that you’re hair glides through. The ceramic plates are then coated with tourmaline gemstones that emit negative ions to give you a frizz-free shine.

So far I like this straightener. I haven't figured out the curling part of it but will be watching some videos next for that. Other than that it does a good job of straightening hair. I have super thick hair with natural ringlets. It usually takes multiple passes to get my hair soft and smooth. This one does a good job b/c it closes properly down on the hair and doesn't leave my hair looking crimped. The hair also doesn't get caught under the blades and rip out of my head like my last straightener. I haven't used the $200 one that is comparable with this one but I am super picky and this is a good straightener!!
FHI’s rounded edge allows you to easily curl or add waves without much effort. It’s almost as small as a travel flat iron, and I love that it straightens even the poofiest sections with just a single pass. But don’t just take my word for it, listen to Beyoncé (via InStyle): “I’m crazy about it! I can’t live without my flatiron! It takes me about an hour to do my hair, and the only time I don’t is when I’m on vacation.”
