The MHD professional flat iron hair straightener is great for creating loose curls because it’s got smooth plates and negative ions that leave your hair soft and frizz-free. The 3D floating plate allows your hair to glide through without catching or breaking, and reviewers love it because it’s durable, reliable, and works on any type of hair — even the most stubborn and frizzy.
While there are a lot of great options to choose from, our all-around top pick is the LumaBella Keratin Duel Touch Hair Straightener. Featuring unique, keratin-infused plates for optimal shine and less damage, the LumaBella Keratin Duel Touch Hair Straightener proves that technology really can make a difference when it comes to hair care! We also love this model’s innovative smart heat sensors that protect hair from heat damage and lock in moisture.
We usually roll our eyes at oil-infused heat tools — but you can actually watch this oil being sucked right out of the refillable cartridge in the handle. When you press the iron closed over your strands, the oil vapor seeps through tiny holes to condition and straighten your hair. And don't worry fine-haired friends: It made our tester's hair silkier, but not like she'd dipped it in an oil vat.
