<font color="brown">Tekmommie is right. If your hair is properly relaxed and set, humidity will cause your hair to droop, not frizz.
I am a Florida native and I live in Fort Myers, FL. I moved here a few years ago from West Palm Beach and I can tell you that it is far more humid here on the gulf coast than on the east coast. Anyway, when I first moved here, I had a problem with my hair drooping and just looking blah. My hair would only get poofy near the roots (new growth). Anyway, I ended up changing the type of styles that I wear, as well as the products that I use to set my hair.
For instance, we went to a fireworks display tonight, but my hair sill looks good despite the humidity. I set my hair last night on smaller rollers than normal (purple magnetics instead of gray). I also used a straightening lotion instead of my normal setting lotion (it helps to pull my roots straighter and locks out humidity). When the set was dry, I did a doobie wrap. With the smaller rollers and the thicker straightening cream, my hair had A LOT of volume. HOWEVER, when I uwrapped it and styled it today, it had flattened some and it looked great. As the day wore on, the fullness started to droop, but my hair fell nicely and kept its shape (especially with my recently trimmed ends). It was still shiny and straight (no frizz), but not as full. Tonight, I wrapped it again and will be ready for tomorrow. Even a doobie wrap done with huge rollers should fare okay as long a the hair is COMPLETELY dry when you take down the rollers to wrap it.
Another style to consider is spiral curls. These can be done with flexi-rods, perm rods, or small magnetic rollers. The good thing about this style is that they look good, even as they fall and loosen. The trick is to use a good setting lotion/gel or styling cream, and to keep the rollers in until thoroughly dry. If you take the rollers out before they are fully dry, you may experience friz, or curls that fizzle out before they should.
Even when I air dry, I never have any type of problem with frizziness - - other than the fact that my new growth can get "poofy" in very humid weather. I simply tie my hair down at night and it seems to flatten out - - especially if I use a little relaxing balm prior to drying. With braid-outs, the poofiness is not very noticeable.
I know each head of hair will respond differently, but I hope some of this helps.
