4. Colour Wow Root Cover Up £28.
Little is more annoying than roots (and the odd grey hair!) showing when you are in between salon appointments, but fear no more. Colour Wow Root Cover Up works like an eyeshadow for hair. Simply apply this powder (available in light and medium blonde, light, medium and dark brown and black) to your re-growth and voila, you'll look salon-fresh!
