Step 1: Start with freshly washed and conditioned hair, towel dry. Use a quarter-size dollop of medium hold mousse (Porter used Sachajaun hair mousse), dispersing with fingers, starting with back of head. (TIP: Never start at front of face, hair always needs most product underneath.) Roughly blow dry (or air dry if you have time) so hair is about 75 percent dry.
