This clever new at-home colouring range will put an end to expensive salon trips

Ever trawled the home hair colour aisles only to leave 20 minutes later, confused, with no box colour in hand? We feel that beauty pain. So, we’re seriously thanking hair colour guru, Josh Wood, who has just answered our DIY prayers.

Here’s what we wish we’d always known. ‘To find your perfect hair colour match you just need to identify your base colour and the corresponding number,’ says Wood.

‘Jourdan Dunn is a 2 (Darkest Brown), Cara Delevingne is an 8 (Lighter blonde) and Naomi Watts is a 9 (Lightest blonde).’ Thinking in colour is second nature for the colour expert of 30 years, whose skills have earnt him a loyal following of royalty and A-listers, who fly him around the world to tend to their roots.

For the rest of us, he’s now sharing his expertise with a new colour system and personalised text support via a 24/7-ready chatbot. ‘You never know when a hair emergency might strike,’ says Wood. Ten questions in and we know our base colour number (we’re twinning with Cara if you’re asking) and have a full colour prescription from Josh.

Clear, number-coding across the range (and easy-to-match swatches replacing the usual woman in a wig) allows you to self-select your magic number from the Permanent Box Colour, £10 - it’s ammonia-free and gives 100% grey coverage. Plus, the colour-care Shampoo and Conditioners, £10, and a tool-kit of Root Concealers, from £8.

With the pro addition of half shades, it’s straightforward to soften or intensify your colour. And the Shade Shots, £5, work like a salon toner to warm up or cool down your colour so you really can stretch (or cancel) your next salon date.

As for tonight’s date – we’re ditching out and staying in to wash our hair.
