I'm relaxed, but no, my hair doesn't revert, but it can. It all depends on the products used to create the style. Typically, styles done with the "dookie" gel last longer and keeps the hair locked in place so it doesn't revert, even in humid weather. But, if you do a set with just some mousse, chances are it will revert. The heavier the setting product, the better. Lottabody is okay as well for holding, but it's even better when mixed with mousse. Those two alone don't satisfy me. That's why I always prefer the brown gel for upsweeps and stuff like that. It's all a matter of preference though, because some people don't like their hair hard or stuck in place. But it helps mine last longer (spritz as well). This is just my own observation.
