Professional hairstylists love BabylissPro's Nano Titanium Prima3000 Stainless Steel Straightening Iron for a good reason: It reaches a temperature of 465 degrees Fahrenheit in seconds and has titanium plates that are longer than usual to help speed up the smoothing process.

The GHD Wide Plate Styler is a must-have for anyone with thicker or longer hair, which is why it nabbed a Best of Beauty Award this year.

Under $250: Harry Josh Pro Tools Ceramic Flat Styling Iron 1.25 Inch
Gisele uses this flatiron. Need we say more? OK, maybe a little bit: From the same hairstylist whose blow-dryer launch nearly broke the Internet, Harry Josh's green-plated Ceramic Flat Styling Iron is equally as buzzworthy. It has plates that are larger than most other irons (meaning fewer passes) and rounded edges that prevent snagging or pulling. And because it shuts off automatically after an hour, it's ideal for those of us who constantly forget to unplug our flatiron before running out the door.

Under $250: GHD Platinum+ Professional Performance Styler
GHD nabbed itself Best of Beauty Award in both 2018 and 2019 with this miracle of a flatiron. The Platinum+ Professional Performance Styler maintains a constant temperature of 365 degrees Fahrenheit, but get this: It reads the thickness or thinness of the sections you use so it can adjust the amount of power it exerts. That way, it keeps the same temperature while straightening your hair and gets all the sections evenly straight without you having to worry too much about heat damage. "My hair felt relatively healthy after ironing which I am not used to," says Tracey Zane, former director of content development for Allure. "The tool moves much effortlessly across my hair, and actually makes it feel silky smooth once ironing."
