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.


STEAM INFUSED WITH ARGAN OIL OR PURE WATER PREVENTS HAIR DAMAGE: Designed with steam compartment that can be used for Argan Oil Serum or water, PureBlackMagic Steam Infusion Hair Straightener releases steam within 60 seconds of heating. The conditioning steam infuses moisture back into your hair, locking in natural oils and adding more shine to the finish.
At $230, the Bio Ionic is pricier than any of our top picks. But you get what you pay for. You can truly do with your hair whatever you desire — straight or curled — in one pass. And, if you’re worried about it breaking a few years after purchase, the Bio Ionic comes with a five-year warranty. By investing in a better-quality tool up front, you won’t have to replace your flat iron every couple of years. Plus, the Bio Ionic goes on sale every now and then, so it’s worth keeping your eye out for deals.
Sure, the drugstore flat iron you used on its highest setting back in the day was clunky and had a tendency to fry your hair if you glanced away for more than a second, and okay fine, your mom probably told you that you looked a little “emo” from time to time. Luckily, those days are long gone and hair straighteners have truly come a long way since the days of The Jersey Shore.
When you’re shopping around for a great flat iron that’ll give you flawless waves, you’re essentially looking for three specific qualifications. First, you want something that’s got one inch plates or smaller. Any thicker, and the curls will be so loose, they’ll be virtually non-existent on anyone whose got hair shorter than the butt. Secondly, a rounded body is a must, as you’re wrapping the hair around and through the straightener to create a loose curl. Third, you need something that’s sleek and easy to handle, so your hair won’t snag and break off while you’re curling. Check out these awesome options that make it easy to curl your hair with a straightener.

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.”

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.

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.
