"The Klorane Dry Shampoo with Oatmilk (£9) is the OG of dry shampoo. It launched years before anyone who wasn't a hairdresser knew the product category even existed. And it's really the perfect formula: It sops ofd excess oil at the roots like a vacuum, adding lift and volume in the process. And while some people may want their dry shampoo to smell like perfume, I personally don't, which is why I like that Klorane's version has no discernible scent."
