We’re all for embracing your natural curls in the summer. But humidity-related frizz is another story. If letting your hair run free ends up making you look as if you’ve stuck a finger in an electrical outlet, you’ll want an anti-frizz product. Regis DESIGNLINE Ultimate Radiance Defrizz Spray ($6.50, Regis Salons) is light enough to soften and tame your curls without leaving them crunchy the way heavy gels do. Just spritz it onto damp hair and comb through with your fingers, scrunching your curls upward as you go.
