Whether you’re heading to the races, a garden party or an art gallery opening, glossy, healthy-looking waves always fit the bill. So, we asked British hair authority Sam McKnight to explain his simple technique for nailing the style. McKnight worked his magic on Mecca Cosmetica Marketing Manager Saira, using the genius Modern Hairspray. The product has serious gravity-defying hold that still allows natural movement—you can add layers and layers and it will never leave hair feeling crunchy or stiff. The only other tools you’ll need to recreate the look are Sam McKnight’s Lazy Girl Dry Shampoo plus a medium-sized curling wand.
