When buying a hair straightener, pay attention to the size, the material, and its features. There are straighteners with wide and narrower styling plates, and they also come in different materials. A straightener with a ceramic coating is usually cheaper, but it wears relatively quickly and therefore doesn’t last as long. Straighteners with plates made entirely of ceramic or titanium protect your hair better from heat and last longer, although you’ll generally pay a bit more for them. You can also look at extra features. With most hair straighteners, you can create curls or waves too. Also check what temperature settings it has and what else it offers, such as an automatic shut-off function.
