California-based hair brand Playa had me hooked the minute I spotted its cool white-and-gold bottles. Luckily, it wasn't just a line of pretty packages. I especially love the Playa Endless Summer Spray (£19), which uses sugar cane (instead of alcohol) and sea salt to coax soft bends out of my not-quite-straight, not-quite-wavy hair texture. It's beachy waves without having to go to the beach — and without having to deal with the knots and tangles that come with it.
