Although it may be tempting to use lukewarm water on your tresses while showering, Lisa Richards, co-founder of RPZL (a New York City-based blowout and extension bar) says that you should always try to rinse your hair with cool water after that much-needed shampoo this summer. Doing so will help seal the hair cuticle, priming your locks for that perfect humidity-proof blowout.

A good treatment mask can also be helpful when it comes to preserving your summer blowout, as it can help tame frizz without making hair feel unbearably heavy. "When you head into the shop to get your blowout, bring in the Evolis Reverse Mask, $40, and ask the shampoo girl to swap out their house conditioner for this," says Susan Roberts-Cooper master colorist and Co-Founder of Colour Collective. "The mask deeply hydrates without weighing the hair down and keeps frizzy ends caused by humidity at bay."

Fighting humidity-induced frizz also starts with the right styling product. It's important to use sun and heat protectors on your strands in order to keep unwanted puffiness and UV damage at bay. "Try to use heat protectors on wet hair before blowing out during the summer. I love to use Rene Furterer Solaire Protective Summer Fluid, $26, as it's both a heat protector and a sunblock, which protects your hair against damaging UV rays," Richards says.

While heat protectors work wonders on hair, it's important to check your product labels carefully. Alcohol can be very dehydrating to the hair and can cause unwanted frizz, says Nelson Vercher, senior stylist at Rita Hazan Salon. To avoid any damage, he recommends looking for moisturizing creams and sprays that are specifically designed to fight humidity. (Try Vernon Francois Leave-In Conditioner, $28.)

Avoiding water-based products is also key to a bulletproof summer blowout as water will cause hair to revert back to its natural, poofy state, says Samantha Sheppard, lead stylist at GLAM+GO. Instead, she recommends using a light serum or oil to smooth out any existing flyaways you may have. (Try John Freida Frizz Ease Extra Strength 6 Effects+ Serum, $11.99)
