If you've got a natural wave that you're looking to enhance, there is truly nothing better than R+Co Sail Soft Wave Spray (£23). I spritz this through my hair when it's about 50 percent dry, give it a scrunch, and then try not to touch it again for an hour or so. The spray adds softness and texture at the same time, something I thought wasn't possible. If you love the effect of a salt spray but hate the gritty, dry texture it gives, meet your new hair holy grail!
