We loved the Bio Ionic’s user-friendly design. Two of our favorite features are its bright digital temperature control and the instructions stamped directly onto the tool. It also feels natural in the hand, and its matte finish provides a slight grippiness, but doesn’t pull at the hair when styling. Plus, the tool sports a uniquely shaped plate that’s curved at the tip and makes it really easy to get close to the scalp. One tester who is new to using flat irons said the Bio Ionic felt intuitive and even encouraged her to try harder styles, like creating curls and waves.

This lesser-known brand made a great impression when it was available on Amazon (you can now buy it at TerresaBeauty.com), where the majority of reviewers gave it five stars. "It allows my hair to glide so smoothly through the plates, never snagging it," says one shopper. "I can straighten or curl with this straightener and it works great," says another.
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 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.
The last time I used a legitimate curling iron, I was getting ready for my eighth grade Halloween dance. This is not an exaggeration. I’ve been using a flat iron to curl my hair since the very day I learned how. One of my closest beauty-savvy friends showed me the basics, I begged my mom for a great straightener that curls hair, and I perfected the skill by watching flat iron curling tutorials on YouTube. Yeah, there’s a slight learning curve, but once you know how to use a straightener to get curls, you’ll never go back to curling irons again. No clips, no burns, no need for gloves, and one tool covers all your bases.

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.”
Early hair straightening systems relied on harsh chemicals that tended to damage the hair. In the 1870s, the French hairdresser Marcel Grateau introduced heated metal hair care implements such as hot combs to straighten hair. Madame C.J. Walker used combs with wider teeth and popularized their use together with her system of chemical scalp preparation and straightening lotions.[3] Her mentor Annie Malone is sometimes said to have patented the hot comb.[4] Heated metal implements slide more easily through the hair, reducing damage and dryness. Women in the 1960s sometimes used clothing irons to straighten their hair.

The Lanxim ceramic tourmaline argan oil flat iron is a great option for this type of style because it’s got one inch plates that have advanced infrared heat technology, an adjustable temperature that lets you personalize the heat levels to your hair, and a swivel cord that won’t get tangled. The floating plates are also infused with argan oil to keep your curls soft and healthy.
This got my hair straight. The teeth on the Iron helped to get my ends straight. So I didn’t have to chase it with a brush/comb. It comes with a comb, 2 clips and a bottle to add the water to the dispenser. No directions on how to add the water. But I looked it up on you tube. I added a couple of drops of Argab oil to the water mixture. This gave me sheen, moisture and protection. The only thing is I couldn’t get my roots. I have really thick hair so I have to get super close to the root but I just used my other Flat Iron to catch the roots. Would still recommend and will be using this method from now on.
According to hair pro Christian Wood, if you want to make sure your hair stays in the place, use the GHD gold mini styler. “I prefer a small straightener that I can get really close to the roots to remove stubborn kinks and cow licks,” says Wood. The small straightener trick is probably how he nails the beauty looks of Tessa Thompson, Emily Ratajkowski, Rosie Huntington, and Olivia Munn.
I ABSOLUTELY LOVE this hair straightener/curler. I was looking into buying the new TYME Iron that came out but found this one that was so similar and more than half the price. After seeing some reviews, I trusted it enough to purchase it. Got it in today and curled my hair (WITH my clip-on hair extensions) and it not only curls/straightens SO pretty but leaves hair nice and soft and silky AND therefore made my extensions blend in so so seamlessly. If you're looking for a new straightener/curler, I absolutely recommend!
This straightener is a miracle worker! African-American women with extremely coarse hair consider this tool a godsend. Thanks to 5-inch extended plates, faster and more efficient straightening is finally possible, especially for those mornings when you’re in a rush. If you want a hair tool that can help you with styling details, this BaByliss PRO is a very good solution.
Available with either ceramic plates (good for all hair types) or titanium ones (choice for curly, thick, and coarse textures), this innovative styler features touch sensor technology that lowers the heat when it's not being used, then automatically brings it back up to temp as soon as it's touched. Translation: No more waiting for your iron to heat up in between passes. Use it for smooth and sleek styles, or take advantage of the round brush-esque attachments to create more of a bouncy blowout effect.
