GET THE LOOK: Go ahead and milk a professional style for all it's worth. To get Blake Lively's voluminous mane three days later, protect hair from three hair-flattening culprits: shower steam (use an extra-wide shower cap), sleep (pile it on top of your head with a scrunchie at night) and workouts (find a thick terrycloth sweatband).
INSIDER TRICK: In the morning, run a ceramic straightening iron lightly over any pieces that frizz overnight. If roots look greasy, use an oil-absorbing dry shampoo (a spray made with kaolin or rice won't cake or clump like baby powder) and brush out.
