(Radio.com) Justin Bieber has been getting a good deal of slack ever since he dreadlocked his bleached blonde hair. But it looks as though even he's had enough of that hairstyle. The Biebs debuted a shorn head on Instagram over the weekend.

In a series of posts, he showed off his newly shaved head. In nearly every one, he wears a serious expression and doesn't provide a caption to better illustrate his mood.

It's unclear why he decided to shave his head after defending them in late April. On Instagram he wrote, "Being weird is fun' if u r not weird I don't like you." Perhaps he finally had enough of the world's mostly negative opinions. Check out the new cut here.
