1. Fortify wet hair with volumizer (mousse, spray, cream) then blow-dry with a round brush.
2. Set hair in medium-to-large curlers; do makeup while you wait.
3. Undo rollers; tease hair at crown.
4. Work in hairspray with fingers for hold; gather upper section of hair into a ponytail, coil into a bun and secure with pins.
5. Pull out sexy tendrils where you see fit; set with hairspray.
