7 Problem-Solving Hair Products
Fight back against humidity-frizz and other hair-raising (and flattening) dilemmas.

THE PROBLEM: UNCONTROLLABLE FRIZZ
THE SOLUTION: When the humidity is high, apply a pea-size dollop of Avon Advance Techniques Lotus Shield to towel-dried hair. The cream's silicones and microparticles block moisture in the air that can swell hair into a halo of frizz.

THE PROBLEM: THE BURNING SUN ON YOUR SCALP
THE SOLUTION: Redken Color Extend Sun Solar Screen SPF 12 contains four chemical sunscreens—including avobenzone and octocrylene—to protect your scalp from harmful UV rays. Separate hair into three sections and spray along the part 30 minutes before sun exposure.

THE PROBLEM: NO SHINE
THE SOLUTION: The sweet orange peel extract in each spritz of Alterna Summer Hair Rx Spray Shine gives hair instant sheen without leaving it greasy; a mix of moisturizing botanicals—including hemp seed oil, white tea, and avocado extract—helps create long-term gloss.

THE PROBLEM: FLYAWAYS AND UNRULY CURLS
THE SOLUTION: The Moroccan argan oil in Kiehl's Superbly Smoothing Argan Hair Pak is loaded with essential fatty acids and antioxidants to smooth hair for defined, bouncy curls. Cocoa butter and safflower oil add an extra boost of moisture. Use it once or twice a week after you shampoo; let it soak in for at least three minutes before rinsing.
