The Bio Ionic worked well on all of our testers’ hair, but it’s best on drier hair with a medium thickness. We spritzed testers’ hair with some keratin smoothing treatment, but the Bio Ionic did a lot of the heavy lifting to make our hair feel softer. The tool gets hot, but not too hot to grip, and it excels at creating the silky volume you want without making your hair pin-straight and flat. One tester put it perfectly: “[The Bio Ionic] is the Rumplestiltskin of hair straighteners. It’s turning straw into gold.”

To solve this problem, CHI’s new G2 Ceramic and Titanium Flat Iron features a digital temperature display located right on the outside of the handle. No more knobs or dials, just buttons and electronic displays, and it is intuitive to use! This feature is great for maintaining an exact temperature during styling and also allows users of varying hair types to experience the professional-grade results CHI hair straighteners have delivered for years without the worry of damage or frying!

The ceramic blue plates aren't just pretty; they push conditioners into the hair, quelling frizz 65 percent more efficiently than a traditional ceramic iron. Even experts were impressed. "[It] leaks heat-protective ingredients onto the hair at the exact point of contact, coating every strand during the straightening process," says cosmetic chemist Ni'Kita Wilson.


I've owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! A lot of research was done before I made the decision to purchase this one, and I feel like it paid off; my previous straightener was 4 years old, so it was about time. I received this new one today before I got home for my lunch break, so I had to go ahead and bust it in ;) There really is no tugging at all on your hair - so smooth, and I was shocked that it truly heats up in 15 seconds, as advertised! It also does something magical to my hair, like it adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. I am a Caucasian, but my hair has always been coarse, wavy, dry and thick! This iron worked beautifully on my hair. 10/10 would recommend! If it doesn't work the same after a few months, I'll be sure to update my review. As of today, I'm very happy! :)
We usually roll our eyes at oil-infused heat tools — but you can actually watch this oil being sucked right out of the refillable cartridge in the handle. When you press the iron closed over your strands, the oil vapor seeps through tiny holes to condition and straighten your hair. And don't worry fine-haired friends: It made our tester's hair silkier, but not like she'd dipped it in an oil vat.
