While Erin, 24, from Fullerton, Calif. can easily pull off the Kerri Russell a la “Felicity” ultra-curl, she wanted to make a change, and went for an ulta-straight style (a bold move for someone who, like Felicity, never switched it up much). But even with loads of chemicals, Erin still needs a little something extra to keep her strands in place, so she applies Sexy Hair Spray and Play Harder Hairspray, $12.75 for extra hold.
