This is set to be the hottest hair color trend for 2021 according to the experts

It's fair to say that 2020 hasn't gone as planned and hair color trends have taken a backseat over the past few months. 

But with a New Year on the horizon, it's time to tap into the 2021's obsession with 'dimensional hair'. Bangs are set to be the most requested hair cut (opens in new tab)but with Zoom meetings still a regular fixture, ringing more lightness around your face and jaw line is going to be a priority too.

For celebrity colourist Nicola Clarke, (opens in new tab) whose clients include Cate Blanchett and Madonna, achieving a soft halo of light around the face "involves adding skinny highlights around the forehead or under a fringe".

Lucky for us, one of the hottest new shades to do precisely that suits everyone and happens to require minimal effort. Say hello to caramel highlights. Brunettes look instantly sun-kissed and it's still bright enough for blondes to take the plunge and gradually fade from darker roots to caramel ends. 

Kate Middleton, the Duchess of Cambridge, arguably kickstarted the trend with her modern take on 90s-inspired caramel highlights. The tones were strategically placed throughout her softly layered hair to make more of a subtle transition rather than a harsh contrast. 

Margot Robbie, meanwhile, has switched from platinum blonde locks to a caramel ombre. Celebrity hair colourist and dpHUE co-founder Justin Anderson (opens in new tab) is the mastermind behind her new look and with a client roster that includes Jennifer Aniston and Miley Cyrus, it's no wonder Margot trusts him to take her a few shades darker.

Moving from platinum into warm blonde territory is tricky - one wrong move and hair can end up on the brassy side and skin can look grey.

But this seasonally appropriate mix of dark roots paired with honey/caramel shades makes Margot's skin sing and her blue eyes pop.

The switch to caramel is timely inspiration as salons have re-opened in the UK and in some states. So when you finally get an appointment this is the subtle hair transformation to request.
