Hot-Weather Hack:My bangs get greasy during the summer, and there’s no way I can go without washing them more often. But instead of shampooing all my hair, I section out my bangs to cleanse just them, then style as usual. And I always carry blotting sheets with me. I dab my forehead when I feel sweaty to keep the oil out of my bangs.
