Her hair looks fine when it's pulled back at the Sicario premiere in New York but it just looks so.. flat and lifeless in those other recent events. The two tone shade really doesn't flatter her at all. She can do blonde for sure, she looked great at Cannes with it but honestly, dark brown is perfect for her because it brings out her eyes. I think she may be a contender for award season so it would be nice to see something different by then. Perhaps she will go shorter?
Nonetheless, she's getting great reviews and it's well deserved. I hope this is the start of some really interesting roles for her.
