1. CRUCIAL PREP

Start with freshly washed tresses. “There’s a fine line between sleek and greasy,” notes Mizu Salon stylist Dominick Pucciarello, who coifs catwalkers like Doutzen Kroes. Choose a shampoo that will suit your needs, be it taming frizz or adding volume, then use a rich conditioner like Wella Color Save Bi-Phase Conditioner (RM76) to yield silky strands.
