    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."

    Splurge: Dyson Corrale Flatiron

    Dyson is back shaking things up in the world of hot tools. The brand, which brought us the Best of Beauty-winning Supersonic Dryer and Airwrap hot tools, has added another innovation to its family: the Corrale flatiron, which has flexing plates that gather each and every strand of hair going through it to apply even heat. That way, you don't have to pass the tool over that section again, which means fewer opportunities for heat damage. The plates are made with manganese copper alloy and are broken up into 15 small segments to mold to your hair. The tool maintains three heat settings (330, 365, and 410 degrees), regulating the heat on each place 100 times a second. Best yet: You can use this tool with or without a cord, just be sure to charge it when the battery is low.
