Well, if it's good enough for Kate Middleton...
It goes without saying that we all adore Justin Bieber, particularly in his less... tactful... moments.
What would life be ike without The Biebs making an over-invested statement about the hair of a Royal?
BORING. THAT'S WHAT.
When asked by Rollercoaster magazine what he'd do if his trademark locks started thinning, the Biebs was horrified. And quite rightly - for all we know the hair could be the source of all his power, and without he'd he'd be reduced to beating tin cans together outside Warren St tube station for a living.
Mentioning Prince William's receding hairline, Justin said “I mean, there are things to prevent that nowadays, like Propecia...I don’t know why he doesn’t just get those things, those products.
"You just take Propecia and your hair grows back. Have you not got it over here?”
That said, if the Biebs started to lose his gorgeous hair, we'd probably have some kind of emotional breakdown.
Thoughts on Justin's - probably unwanted - advice?
