Dry Shampoo Foam

The humble dry shampoo – pretty much everyone’s handbag beauty staple since time immemorial – has got a 21st Century update. Enter OUAI’s innovative new foam version. Its secret weapon is something called diatomaceous earth, which dissolves oil and grime without leaving any chalkiness and contains panthenol to hydrate your tresses in the bargain. It’s also a volumiser, so if you want to give your barnet an extra boost, work this foam right down to the ends for swoosh-worthy strands.
