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.

Living Proof Perfect Hair Day Shampoo and Conditioner, $24 each, contain a patented anti-humidity molecule that was created by MIT scientists. It's called OFPMD, and it coats the hair like silicone -- but works so much better and never feels heavy. The TotalBeauty.com Award-winning shampoo and conditioner are infused with the ingredient, so you can load up your hair with frizz-fighting power even in the shower.
