Klorane's dry shampoo is one of the best-selling formulas in the world (according to the company, one sells every 16 seconds). This month, the French brand created a new version of its famed root refresher, the Klorane Aquatic Mint Detox Dry Shampoo (£9). Infused with aquatic mint (which the brand grows organically), this version helps protect your scalp and hair from pollution, be it dust, hard water, cooking fumes, tobacco smoke, you name it (the plant has been used in French mining towns to decontaminate polluted waters). In addition to being completely invisible (unlike the original), the mint provides a cooling effect on your scalp, while the natural rice and corn starches absorb up excess oil lingering around your roots.
