Big, voluminous hair is going to be huge (ha!) for fall. Tons of stars at the Emmys rocked this look, including Jayma Mays, and it was all over the runways at fashion week. Guido recommends using a volumizing spray (try Suave Professionals Volumizing Root Lifter Spray Gel, $3.09) to help add oomph. That paired with some teasing comb action will give you volume at your crown.
