How to choose the perfect hair straightener for your style

First of all, it’s really important that you choose the right shape. You may think that a flat iron is, well, flat(!), but the edges of straighteners can actually affect their versatility. If the outer edges are slightly rounded, it’ll be easier to transform your straighteners into curlers, meaning these models are ideal if you prefer diversity in your up-dos. In fact, we've put together a styling blog for getting the most out of your hair straighteners. A flat iron with sharp edges, on the other hand, is less adaptable, but may give you slightly straighter hair. GHD hair straighteners are renowned for their adaptability, as are Remington hair straighteners and CLOUD NINE hair straighteners.

Next, consider the plates. Aside from their width, plate materials are also worth thinking about, as these are what actually touch your hair. Titanium irons (as showcased in BaByliss’ Graphite Titanium straightener) heat up quickly, applying higher temperatures more evenly. They tend to be suited to very coarse, curly hair, thanks to their ability to make all hair types look sleek and smooth. For an equally-successful alternative, though, try ceramic plates, instead. Check out our hair straightener buying guide to help you work out which is right for you.

Other features to consider

Finally, think about extra features (like portability in cordless hair straighteners, or safeguarded locks in steam hair straighteners, for instance). If you’re interested in a fantastic multi-purpose flat iron, that you won’t have to change any time soon, you can’t go wrong with Dyson’s Corrale. This model uses thin copper alloy plates to gather more hair and straighten it in fewer passes, making the process much quicker and more streamlined. Other popular brands include Dive and Kipozi.
