Whether you color your hair, blow-dry or you’re heavy-handed with a flat-iron, the result can be tired and stressed out locks. (Especially in the summer, too!) Luckily, Emily Blunt filled us in on her quick fix for over-processed hair: Moroccanoil’s Intense Hydrating Mask. "My hair has been damaged so much by color, and this mask has recovered it," she told us. "Sometimes I sleep with it in my hair." We need this, stat! Pick up the mask for $33; visit for a list of salons where it is sold.
