Justin Bieber, who is famed for his luscious locks, has slammed Prince William for his thinning tresses.
The ‘Boyfriend’ hitmaker took a jibe at the Royal for not trying to combat his baldness even though hair treatments are widely available.
The 18-year-old expressed his horror at William''s receding hairline when he was asked in an interview what he would do if his own famous locks started thinning.
"I mean, there are things to prevent that nowadays, like Propecia," the Daily Mail quoted him as telling the Rollacoaster magazine.
"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?" he added.
