Fellow blondies, I’m going to educate you. Let’s go back to school. Remember the colour wheel? The complimentary colour for yellow is purple. What does this mean for you? When your icy-bright blonde highlights turn crabby, you need violet shampoo. Three words: Davines Alchemic Shampoo (13.75, 020 3301 5449). What it can do for you! Not only is the stuff eye-piercingly purple and served in a Calpol bottle, there is a real science to it (pigments). The conditioner (17.90) is also beautiful. But if brightening just won’t do, take a more drastic measure. Come on, John Freida, come forward. The brand-new Go Blonder Controlled Lightening Spray (6.99, johnfrieda.co.uk) gives a magical boost. Just spray into the roots and the lengths, blow dry and sparkle.
