9 tips to sweat- and frizz-proof your summer

Frizz Fixer

If scorching temps turn your hair into a halo of frizz, switch your rinse-out conditioner for a leave-in version, says celebrity hairdresser Scott Cuhna, who has worked with Nicole Richie and Miley Cyrus, among others. “After washing your hair, spray on conditioner from the roots to the ends,” he says. His product pick: Lait Luminescence by Leonor Greyl.

Cut With Caution

As much as you may be tempted to chop your hair come summer, think before you lop. “Long hair is actually the best in the heat, because you can pull it up,” says Cuhna. Instead, experiment with trendy, slightly mussed updos. Keep errant hairs in place with this product.

The Shield

Blonde and highlighted hair is especially susceptible to sun-induced color havoc. So protect your locks with a spray-on product packing SPF, recommends Cuhna. He likes Rene Furterer Protective Summer Oil KPF 90, which features naturally protective sesame oil, combined with a UV sunscreen.

Lay It On Light

Heavy creams can clog up pores when it’s hot out, says L.A. dermatologist Dr. Jessica Wu. Replace thick concoctions with light lotions or—on really blistering days—a water-based serum. And be sparing with hydration: “I always tell my patients, you only need to moisturize where you feel dry in the summertime."

Soft Sell

Simplify your beauty routine this summer by using a two-in-one hydrating product, suggests Cunha, who adores Leonor Greyl Huile De Magnolia—a vitamin-rich blend of botanical oils that can be used to condition and soften skin and hair.

A Cookie Cure

To jumpstart skin’s vitality, whip up Dr. Wu’s Oatmeal Cookie Scrub: Combine ¼ cup rolled oats, ½ teaspoon cinnamon, 1 teaspoon vanilla extract, 2 teaspoons honey and 1 tablespoon plain yogurt. Smooth the mixture over your face, let dry and rinse. The oats contain proteins that help dissolve oil, while the yogurt has lactic acid to help unclog pores.

Puff Piece

If pollen and grasses leave your eyes puffy and red in the spring and summer months, then dunk cotton balls in soymilk, says Wu, and hold them over your eyes. “The soy proteins are very soothing,” she adds, warning that heat (i.e. a warm washcloth) can only make matters worse.
