Why we love it: Expensive hair tools aren’t necessarily “better” than affordable dupes, but they typically offer more features and precise controls—basically, the difference between a five- and three-star hotel. If you want a tool with a cordless design, “smart” technology, or fancy plates, expect to pay a bit more.

The Dyson Corrale is a very expensive pick, but according to numerous Cosmo staff, it’s 100 percent worth the splurge (especially if you can score it on sale). At the end of the day, how much money you spend on a hair straightener comes down to preference—not performance alone.

This tool relies on copper hot plates with a flexible design that moves with your hair for more even heat distribution and less hair damage. While the Corralle cannot be used on wet hair, it is cordless.

One Cosmo editor says: “I know everyone loves a Dyson dupe, but I can’t help but be loyal to the OG tools. While yes, pricey, they always give my hair the longest lasting results and speed up my styling time immensely.”—JASMINE HYMAN, ASSISTANT BEAUTY EDITOR
