This Italian born actress has a great long formal style, accentuated on the combed back side with a single braid. Amy Adams has her honey blond length in a couple of large vertical spiral curls.
Though most of Amy Adams long hair is straight, perhaps everywhere but this one lock, it is a faux asymmetrical design. This is an easy to achieve style as you incorporate only one ringlet on one side or both, depending on your time or mood.
Amy Adams has an alluring look brushed back on one side while the other is volumized to its fullest potential. The neat trick about flatirons with round backs, is coercing the hair in directions only limited by your imagination.
These S-waves on Amy Adams' hair are easy to achieve since the curling iron is only applied for a few seconds on each section. What encourages the fullness she has in this all-one-length surprising to some, is the way the bottom has been cut.
