Want to keep it longer? Opt for the looser shag style that’s proving popular among celebrities like Daisy Edgar-Jones, Silvia Dionicio and Natasha Lyonne.

East London based hair stylist Adam Reed told GLAMOUR that the shag is easy to style with maximum effect. “It can be worn natural, soft and fresh (you can leave it to dry naturally, it doesn’t need a lot of time spent on it) or, if you want, it can be styled [with heat],” he explains.

Luke Hersheson, hair stylist and CEO of Hershesons, agrees: “If the layering is done well it shouldn’t take too much styling. You should be able to wash it, leave it to dry and it will fall into place.”

Some might say the shag haircut is liberating, since it requires almost no styling to look its best. In fact, if you really did just roll out of bed or left it to kink and curl naturally as it dries, you’re only adding to the vibe.

And it looks like the shag haircut is here to stay: “It will definitely further push the era of grunge,” says Bradley Deeming, senior stylist at Buller And Rice. “Think undone and tastefully messy ‘dos with a strong shape, evolving current beachy looks.”

But there are a few rules when it comes to nailing the shag haircut.

Opt for layers

Bradley suggests choosing a style with plenty of layers and choppy, sliced ends — and even a curly fringe à la Selena if you’re feeling bold.
