We spoke to the stylist for our shoot with Leonardo Dicaprio, Natalia Bruschi, to get the scoop on how to achieve his signature brand of graceful messiness. "On his wet hair, I applied Oribe Gel Serum and then combed it through into a side part. Once the hair was partially dried, I broke it up a bit." Gel Serum isn't a hard product, so you won't get the kind of stiff helmet head that you could crack an egg on. Instead, once it's dry, your hair will loosen up and soften, leaving enough hold to give it a sort-of-orderly-but-still-sort-of-messy look.
