For most of us, 2021 has meant we've had to take a hiatus for the hair salon, but as restrictions begin to ease and life appears to be resuming, we're already planning which hair colours and trends to try this summer...

Of course, our first port of call was Instagram - more specifically - the IG feeds of our favourite hair stylists, salons and influencers, to see which looks are getting all the likes. From Bleach London, who have mastered some of the boldest colours out there, we're talking metallic rose strands and a slime-green dye job that'd make even Billie Eilish proud... To hair stylist Samantha Cusick (who tends the locks of influencers Niomi Smart and Zoe Sugg), and who's London salon has single-handedly convinced us we need to go bright blonde for summer with this dreamy milky balayage.

So, whether you're ready for something a little dramatic this season (if so, let us point you in the direction of slide five) or you want a low-key hair makeover (slide ten will give you all the feelings, trust), we've covered all bases to bring you the hair colour trends that are about to blow up...

1

Honey-tinted strands

Every single thing about this honey-tinted hair colour sparks our joy... With a mixture of lighter and deeper blonde highlights, it's the perfect summer hue.

2

Metallic rose

I'm sorry, but can we all just take a moment of appreciation for this metallic rose hair colour? It's quite possibly the most beautiful shade we've ever seen. `

Rainbow strands

A pastel rainbow underneath our locks? Sounds like the 'My Little Pony' hair colour we've been dreaming of since... well, forever.

Goldilocks

Just when we thought we'd seen all our favourite hair colours for summer, influencer Tamie Lawson gave us golden braids - and our hearts skipped a beat.

Sandy Beige

Blondes don't have to be oh-so bright to give us the feels, this sandy-beige shade is sophisticated, chic... and probably our next hair colour.

12

Ultra-Violet Rinse

Want to go bold without going OTT bright? Let us introduce you to these silky lilac-tinted lengths.

Copper Babylights

Copper is set to be the hair shade of summer 2021, but if you don't fancy going all out with a full head, try adding a few babylights through the lengths.

14

Toffee Blowdry

In the past, cool ashy blondes have reigned supreme, but not any more... Yep, warm blondes are back people - and this look is our ultimate inspo.
