Long Barrel Curling Iron

This is our favorite curling iron for long hair, and, frankly, anyone who is tired of contorting into uncomfortable positions to curl their hair. It’s an 8-inch barrel, so most people should be able to wrap entire sections and get soft curls on the first pass. Four barrel sizes available: 0.75, 1, 1.25, and 1.5 inches (all discounted).

It is designed with a clamp to avoid mid-curl slippage, but in testing, I’ve found the aftermath creases to be super minimal and temporary. Temperature ranges from 250 to 430 degrees Fahrenheit to cater to all hair types. And because it gets so hot, I especially love the cool-touch grip that’s sculpted to fit fingers and make styling less painful. Bonus: it’s dual voltage, so you don’t have to think twice about packing it for international voyages.
