Sick of summer frizz? You’re not alone. Fortunately, there are numerous products out there to help you battle brutal humidity. Our favorite wallet-friendly find is Garnier Fructis Anti-Humidity Smoothing Milk ($4.49 at drugstores), which contains fruit micro waxes to seal out moisture. If you’re prepared to splurge on a solution, Ouidad Climate Contral Heat & Humidity Gel ($23 at Sephora) is a heat-activated gel that contains a wheat protein complex to shield hair from humidity and prevent hair from expanding.
