Blow-drying in sweltering heat? No fun. We prefer to let the air do all the work. Just master this method from hairstylist Ward, who worked on this year's Sports Illustrated
swimsuit issue in the steamy Philippines: 1. Comb mousse, like Living Proof Thickening Mousse ($26; sephora.com
), through medium-wet hair and then leave alone. 2. Twist two or three sections of hair and clip up into mini chignons; let dry fully. The result? A loose, wavy texture that's summer-perfect.
