Ever since the early 2000’s when the planet collectively decided that straightening our hair to death was a good idea, beauty companies have been searching for a way to achieve beautiful and natural-looking straight looks without frying or unnecessary damage. From ceramic plates to protective sprays and everything in between, we have been desperately searching for some way, any way, to show off a straight head of hair that isn’t entirely made of straw.
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.

Featuring the same 1.25-inch plates CHI users have loved for years, the new CHI G2 Ceramic and Titanium Flat Iron make it easier to style longer hair! If you’ve ever tried to use a non-professional hair straightener on your hair, then you know just how quickly the process can become a literal pain! From hand strain to sore wrists and arms, most hair straighteners stick to old adage of “beauty is pain.”


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.”
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.
