I’m a big proponent of going as long as possible between shampoos but usually when I’m nearing day 3, and sometimes even day 4, I’ve got to get creative so that everything still looks “day 1″. For most, the battle between dirty hair and good ole’ shampoo is won by grease. When your roots begin to look like they’ve been pomaded, it’s probably time to suds up. But before you throw in the towel, a cute scarf conceals the grease and is oh-so-adorable in the summer with some cut-offs or a maxi!
