Your success rate relies heavily on the heat of your iron and how quickly you can flick your wrist. Flatirons can take a while to heat up and, if they’re not hot enough, you end up holding hair inside the iron for longer, which is what causes the kink. You may have better luck using a clamp-free styling wand instead—nothing holds your hair in place except your hand, and high-quality ones, like the T3 SinglePass Whirl ($150, at Murale), heat up quickly and stay that way for even, kink-free curls.
