Josh Rosebrook is a talented hair stylist, turned product guru who at the behest of his clientele and friends began churning out his famed concoctions (it all started with his Cacao Antioxidant Mask) that's evolved into his own line. He's since amassed a team to fine tune his products, and while his skincare continues to earn enthusiastic reviews, it's his haircare that I'm obsessed with. Particularly, his volumizing spray. Just three sprays before a blast with a blowdryer, and I've got perfectly blown out hair. Separation, volume and no cloying scent.
