The Best Hair Straightener

After spending countless hours of research and more countless hours on testing the grip, heat, and performance of different hair straighteners on different people with different hair textures, the GVP Digital stood out from the competition with its adjustable temperature in 10-degree increments, and an easy-to-read digital display that updates in real time so you know when it’s ready, unlike like the rest of the straighteners we tested.

The GVP Digital’s temperature range is as wide as the rest of the competition’s, and its plates are big enough to grab a strand of hair without being too big to maneuver. It heats up as quickly and is about as light as the rest of the straighteners, and the casing never snagged our hair. The 9-foot-long cord means you won’t have to lurk near a power outlet, and its auto-shutoff feature keeps your home and belongings safe. The casing is solid black, and the design is simple and straightforward, but it doesn’t look cheap.


If our pick is unavailable, we recommend the Rusk W8less. It was the third-lightest hair straightener we tested at 0.50 pound, but the slim plates get just as hot as the GVP’s, and the cord is the same length. The smaller design of this straightener makes it great for curling or flipping hair. It also fits nicely in a suitcase.

If you find yourself going through new hair straighteners on a semi-regular basis, the Conair Infiniti Pro offers the longest warranty—five years—among the hair straighteners we tested. The 1-inch-wide model is lightweight at 0.51 pound and comfortable to hold. The plates are also an inch and a half longer than our pick, at about 5 inches, which can make it cumbersome to flip or curl hair but is useful if you want to work with thicker sections of hair at once.
