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.
“The temperature of the iron can determine the curl pattern on hair that tends to fall easily, as you might need a higher heat to lock in the pattern closer to the root,” she added. “The internal components of the irons also can determine the curl pattern, and that is why it is important to invest in custom, high-end tools that contain internal heaters that go the entire length of the barrel. The higher the heat, the stronger the curl will essentially be. Low heat will produce a softer finish.”
Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about the best curling irons, hair dryers, and even a certain curling iron used on the Victoria’s Secret Angels, here, we’re going deep on the best flat irons and hair straighteners on Amazon. (Note that reviews have been edited for length and clarity.)
Coming in at a close second, the CHI G2 Ceramic and Titanium Flat Iron is our second editor’s choice as the best hair straightener on the market today – featuring fool-proof and color-coded temperatures for easy straightening or who just wants to protect their luscious locks. We also love the digital display that is featured on the CHI G2 model along with its combination ceramic and titanium design for optimal shine!
“I’m in ‘ahhh’ at how awesome of a straightener this is. If you ask me, it’s a lot better than the high-end brands. It leaves my hair silky-smooth and shiny. I absolutely love its features, and you can watch the heat meter rise as it’s heating up. To me, five stars is not enough to rate this product. It’s definitely worth the money. I’m in love with this straightener. Also, the lock on it I found to be a awesome bonus.”
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.

Before explaining the advantages, let’s discuss the heating process. Flat Iron does the basic purpose of heating so that the hair follicles can flatten. Flattening of follicles is needed to create any hairstyle. Hair follicles contain natural moisture. When we heat the hair, the natural moisture gets eliminated. That’s why hair ends up with the rough texture.
Given its tiny stature, it is no surprise that the BaByliss Pro Nano Titanium Straightening Iron is ideal for users with short or medium hair lengths. Unlike the more industrial models we reviewed that are designed for longer or thicker hair, this BaByliss hair straightener is small and light enough to polish off a short bob or shoulder-length style in no time.

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.
