Our two testers with kinky and thick hair loved the Chi Air Expert Classic Tourmaline Ceramic Flat Iron. In fact, it was each of their top picks, with the Bio Ionic coming in second. The Chi Air reaches 410 degrees F, which is definitely hot enough for thicker and curlier hair types. The speed at which the tool worked was surprising considering the kinkiness and thickness of both testers’ hair. One tester with long, curly hair had to leave early for an event and needed to finish styling. The Chi Air moved through her hair quickly, giving her time to spare. And, even at 410 degrees, our testers didn’t feel like their hair was being fried or that the heat burned their heads. In fact, they complimented how soft it made their hair feel and how comfortable it was to use, unlike the NuMe Megastar which snagged a lot or the HSI Professional Glider which felt hot against their scalps. As one tester said, “Chi is killing it.”

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.”

Do you have curly, dry hair? Thick, color-treated hair? Short, straight hair? Fine, kinky hair? Finding the right flat iron for you really depends on your hair type. Heat and plate types are an important factor in this. Your flat iron should reach and maintain the right temperature and be made from the plate material that works best for you. While most will work well on a variety of hair types, pay close attention to reviews from people with hair similar to yours (bonus points if they include before and after pictures).
Those with fine hair can keep the straightener at a lower temperature, while those with thick hair can increase the temperature to ensure they'll walk away with the same smooth results. No matter your hair type, the floating plate design and the curved edges of the plates themselves prevent any snagging or damage so your hair will glide through smoothly.
As an added bonus, titanium has also been found to resist rust, so your hair straightener will keep its out-of-the-box look for years to come. This is particularly important when you are making a long-term investment by purchasing a high-end or professional hair straightener. After all, you wouldn’t want your car or bathtub to start rusting after just a couple of uses and the beauty tools you use for your flowing hair should be no different!
The HSI 1st Gen Professional Ceramic Flat Iron is designed with tourmaline-infused ceramic plates, generating negative ions and allowing smaller water molecules to penetrate into the hair shaft to reduce frizz and static. Built for durability and lasting results, the floating plates give the flexibility to flip, curl or straighten your hair – all with a single iron.
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!

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.
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.
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 nano ceramic plates in this straightener deliver far-infrared heat, a gentler alternative in and of itself. As if that weren't enough, there's also a reservoir where you can pour in some of the (included) argan treatment and thermal protectant, creating a conditioning steam that will strengthen and safeguard strands while you straighten. Admittedly an extra step, sure, but one that's well worth it.
