But if we've learned anything, it's that hair colour trends move fast. While all-over copper looks incredible, one top colourist is making a case for a brand-new way to wear the trendy shade – and it's perfect for colour commitment-phobes.
Enter: hot roots.
The colourist behind the innovative copper hair look shared to Instagram last week is James Earnshaw, hairdresser and amika artistic ambassador. Inspired by none other than hair chameleon Billie Eilish, James dispelled the idea that copper only works on light hair, teaming the burnt orange shade (concentrated solely to the top for an effortlessly cool, grown-out vibe) with dark brown lengths. Starting right at the root, the copper, which stops just short of halfway, melts into the chocolate shade, complementing the red tones.
James shared a video of the process and used the caption to explain exactly how to achieve the look.
James then washed off the lightener and used Wella Perfecton By Colour Fresh (a colouring rinse) which gave the hair a starting point. He left the roots for a moment and turned to the mid lengths to ends, "smudging" the hair with Wella Colour Touch in 5/0 and 5/1, to keep the colour simple and flat in tone. Then it was back to the copper roots. James looked to Wella Colour Create in Infinite Orange and Future Yellow. He mixed the two, let the colour develop for a further 30 minutes, and styled the hair in shaken out waves to appear lived-in and bursting with bedhead texture.
James admitted that although hot roots sounds straightforward, it's not that easy to master. For a look like this, it pays to book into a trusted salon for a professional treatment, especially if your roots require considerable lightening. Ensure your appointment involves a consultation so that your colourist can conduct a patch test and discuss the best copper shades to suit your skin tone.
