Justin Bieber has had a HUGE hair makeover and he showed it off on October 10, upon arrival in London according to sources. 

Bieber stepped off his private plane in UK arriving for a concert, and sported ‘brown hair’ instead of his dirty blonde.

He was seen wearing glasses (eyesight) and looks studious and sexy.

Bieber performed for his ‘Purpose’ tour at the O2 arena in London yesterday.
