Smooth Sexy Hair: Frizz-Controlling Tricks

When it's steamy outside

Humid days don't have to mean unruly hair. To preempt fuzzies, forget shampooing -- scalp oils make a great natural moisture barrier -- and whip out your flatiron or curling iron. A good one: Paul Mitchell Express Ion Curl TurnStyle ($138, salons). "The combo of heat and pressure seals the hair shaft so tightly that it takes a great deal of moisture to penetrate it," Hawkins says. (Don't iron more than a couple of times a week, though; it'll parch your hair and exacerbate frizz long-term.)
