Nope Jared still hasn’t got the haircut yet as the Joker:

On December 24th, 2014, Jared Leto posted an old photo of Jared Leto with a haircut to his Instagram, which he captioned “Haircut. #2015.” Interesting. However, he has not yet gotten a haircut.

How do I know? Good question. I know because he tweeted a photo of himself without a haircut. See for yourself:

Joker haircut has yet to appear

Waiting for the new haircut as he’s going to play the joker in the new 2016 movie!
