Say goodbye to the brunette!

After wrapping up principle on season four of her HBO show Girls, Lena Duhnam decided to lighten up... her hair that is!

The 28-year-old actress and show creator posted a selfie on Instagram to commemorate the moment which showed off her new platinum blonde look complete with a bowl cut, adding the "change is good."

Maybe she wanted a change of pace before embarking on her book tour for the memoir, Not That Kind Of Girl: A Young Woman Tells You What Shes Learned next month, or maybe she got tired of the same old look.

In either case, what do you think of her new 'do?
