If you've been put off getting a bob because they're such hard work, I have to admit, you're not entirely wrong. As someone who took the chop and entered their bob era recently, they can require a bit of effort – whether that's frequent trims to keep them in shape or a little more time spent styling in the morning (FYI: the Shark FlexStyle has been a saviour for me!) For Sofia Richie Grainge, though, that clearly isn't the case.

The model debuted one of the most low-maintenance bobs we've ever seen, but still looks like she's just walked out of a professional hair salon. Given that she's currently pregnant, it's no surprise that Sofia has opted for a bob that won't require hours spent in front of a mirror, instead going for a more undone, tousled look.

Inspired by Sofia and, tbh, the fact we'll do anything for an extra few minutes in bed before heading into the office on these dark, cold winter days, here are six 'undone bob' hairstyle ideas...

The SRG undone bob

We'd be remiss if we didn't start this hairspiration round-up with Sofia Richie Grainge herself. The 27-year-old traded in her usual middle-part to achieve her undone bob look, instead opting for a sweeping yet totally effortless side-part. She didn't stray from her go-to (and super low-maintenance) ombre strands, though. Roots? Never heard of them.

The just-rolled-out-of-bed undone bob

Gracie Abrams is the epitome of 'cool girl' with this dishevelled yet enviable look, styled by Bobby Eliot. The choppy lengths and untamed flyaways come together in a tousled but not-trying-too-hard way.

Thought you can't have braids with a bob? Think again. This shoulder-length bob with micro-braids at the root proves you can achieve just that. We also love the slightly longer strands that effortlessly frame the face without being over-stylised.

The wet-look undone bob

Although model Gigi Hadid has clearly just hopped out of the pool in this photo, she's giving us major inspiration for a wet-look undone bob. If, like me, you haven't got a pool in your back garden, replicate Gigi's look with a squeeze of Color WOW's Pop & Lock High Gloss Finish serum or a spritz of OUAI's Wave Spray.

Tousled strands are arguably the defining marker of an undone bob, which Rochelle Humes does here with a more polished finish. Recreate Rochelle's effortless style with something like OUAI's Anti-Frizz Creme or JVN Hair's Complete Air Dry Cream.

Go for two trending haircuts in one with curtain bangs to complete your undone bob. Although it will take a smidge more styling than Sofia's OG undone bob, the results are more than worth it. Simply run an air styling brush (like the Revlon One-Step Hair Dryer and Volumiser) through your fringe and across the ends to create that flicked silhouette.
