1. Don’t dry your hair all the way, and use a gel. Keeping your hair damp and then coating it in a managing product keeps water molecules from puffing up your hair the minute you walk outside. If you have fine, straight hair, though, this might not work as well for you, since flatness is already an issue.
  2. Use plenty of hairspray. Hairspray coats your hair and holds it in place, so excess moisture won’t penetrate the cuticles causing your hair to fall flat.
  3. Wear a rain bonnet. An umbrella may keep you reasonably dry, but to keep your hair truly out of the wet, an old-fashioned plastic rain bonnet is the way to go.
  4. Use dehumidifying spray. An antifrizz spray is a real help for people who are constantly battling overly poofy hair, as it acts a barrier between your hair and the surrounding moisture in the air.
  5. Braid it. Braiding is one of the easiest ways to keep frizzy hair under control. Plus, it’s a look that holds better in rainy wind than most other types of styles.
