"If you're thinking, 'What the hell is a dry hair mask?' you're not alone. I, too, was confused when getting my hands on Antisocial Dry Hair Mask ($34). Think of it as sleeping mask — a mask that you leave on overnight and don't have to wash off in the A.M. — for your hair. Before heading to bed, I spritzed this fine-mist spray onto the lengths of my hair and threw it into a loose bun. I woke up to defined waves that were silky soft and had an unmatched, brilliant shine," — JC
