Lena Dunham has gone green during the Canadian leg of her Not That Kind of Girl book tour.
We're talking hair - as opposed to environmentally friendly action, though guaranteed she supports that too.
That's right, Lena's signature platinum blonde look is out. The girl is now "minted".
The 28-year-old American actress, screenwriter, producer, director *and* author posted these photos on Instagram on Thursday.

Man, we wish we were this adventurous when it comes to our hair.
Lena has been working her super sharp bob since August, and she definitely suits being short.
As far as hair trends go - colour is big this season.
While Kate Hudson was doing pink pastel streaks on the red carpet this week, Suki Waterhouse went brunette earlier this month and Rihanna's debut cover for Tush Magazine saw her go grey - it's Lena who's doing the green thing.
Thoughts? Minty fresh or just not cool?
