Take those two side sections that you separated out and pull them together to create a tight ponytail at the top of the head. It should be in line with the first ponytail, but not directly above it — more at the the crown of the head so that it will be easy to conceal later on. Be sure to smooth the sides up so they are super-tight against your head. Diaz recommends spraying a bit of hairspray on your hands and smoothing it over the sides to take care of any flyaways and achieve that sleekness.
