Joico Humidity Blocker Finishing Spray, $17.99, is incredibly light, but still has a good amount of hold. It will lock your style -- curls, volume, you name it -- in place despite the weather. And the scent is refreshing with a hint of sweetness.

If you color your hair, Colorproof Humidity Rx Anti-Frizz Weatherproof Spray, $25, is for you. It contains special polymers that protect your color while creating an invisible shield against moisture. When you use this spray, rain drops literally bead up and roll off your hair.

L'Oreal Professionnel Liss Unlimited Double Serum, $26, contains both a cream and a serum -- for hydration and shine, respectively -- that combine when you use it. It's packed with evening primrose oil and wheat proteins that help smooth the hair's cuticle as you heat style -- meaning each strand is healthier and naturally more humidity-resistant.

As the name suggests, Rusk Freezing Spray, $20, is the strongest of the bunch -- it will literally freeze your style in place. After you spray it, the polymers dry to create a scaffolding-like structure around your hair. While the hold is incredibly strong, the formula is also gentle enough for color-treated hair, and it washes out easily.

Unlike other hairsprays, Big Sexy Hair Weather Proof Spray, $18.95, has no holding power. Instead, it's designed solely to repel humidity. It also contains a UV filter to protect your hair (and hair color) from the sun, as well as keratin to strengthen individual strands.
