If you have very short hair like Halle Berry, Stone says that you can mess it up a bit before the party or change it by adding a shaping product such as a paste.
For long hair, Stone recommends rolling your hair in the morning (he likes to use Caruso Steam Rollers). "Use bobby pins or pin curl clips to secure rather than their curler caps," he says. Leave curlers in for 20 to 30 minutes, then put your hair up in a ponytail for the workday. "That keeps the curl sort of set into it," he says. "For the party just let your ponytail down, turn your head upside down, get some spray in your roots and you can also tease your roots a bit and then flip your head back up to give yourself volume. That is going to give you a full-bodied holiday look…tease at the crown for a terrific 'Mad Men'-like bouffant."
As an alternative, wear your hair long to work, and then put it up before the party. Stone suggests pulling hair up in three sections. First take each side and tease it, pull it back and up, twist and pin to the side of the head. "That accents the cheekbone," Stone says. Then put up the section in the back, pinning it to the head in any way you like. "Don't be afraid to play with it," Stone says. "If you don't like it, just take it down and start over." Add sparkly, decorative hair accessories to dress up the look for the holidays.
