She jumped on the bandwagon!

Lena Dunham has never subscribed to societal beauty standards, and if that wasn't already clear, she just chopped off all her hair to make her point.

The Girls star debuted her new look on Instagram today, and we've gotta admit we don't think it's the most flattering hairstyle for anyone! First Miley did it, then Katy Perry, and now our favorite HBO darling. Put down the scissors, ladies!

"Your mom's therapist friend she leaves your dad for," the actress captioned the pic. That's actually pretty funny!

This is totally something Hannah Horvath would do!
