If you like your hair sleek and pin-straight, or just smooth and frizz-free – and want that style to last more than a day – then you should invest in a premium flat iron. You really will see a difference in both how your hair turns out, ease of use, less damage, and longer lasting results. Why are they better? The titanium or tourmaline heat plates are safer and let hair slip through easily, and more expensive models offer customized heat settings so that you aren’t using a setting that is too high for your hair, or too low to be effective. They also usually come with warranties and other safety gear, like heat-protecting gloves, so you can rest assured in your splurge. A premium flat iron will cost about $125.
