Justin Bieber and Harry Styles are both growing their hair out, and it obviously has us swooning. Whose long locks do you prefer?

Justin Bieber debuted his longer locks on 'Ellen' this week, sporting blonde hair that falls oh so perfectly over his ears. For a singer whose hair is almost as famous as his music -- R.I.P. the Swoop -- there's no question that JB's hair is gonna be talked about, and often. Of course, the Biebs gives us something to talk about, rocking a grown-out 'do that is perfectly fitting for the 'Home to Mama' crooner's more mature transformation. It's fun without being unkempt.

Harry Styles has been growing out those curls for a while now, donning his enviable brunette locks everywhere from the red carpet to the stage. While we'd practically give anything to be able to run our hair through those luscious locks so long as they reach past his shoulders, we'll try and restrain ourselves.
