PRINCE William looks a staggering eight years older – because of his thinning hair, experts claim.
The heir to the throne has the appearance of a 42-year-old man – even though he is only 34 – because balding ages men more than any other physical trait, adding up to eight years on to the age of sufferers.
Greying hair adds seven years, with excess weight, having man boobs and sporting a moustache all following suit, each adding an average of two years.
The findings came from a survey of 1,000 people by Crown Clinic in Manchester, one of Britain’s top hair transplant centres.
It means a silver-haired star like George Clooney would look 48, rather than his real age of 55, if he were to start dying his hair.
Likewise, because having a full beard puts five years on the age of men, a 41-year-old David Beckham would look 36 if he were to have a shave.
The fourth biggest ageing factor was having a goatee which ages men by four years.

So, Cowell would look 54 if he shaved rather than his real (unshaven) age of 57.
England football captain Wayne Rooney is 31 but would have the looks of a 39-year-old if he had not take steps to address his baldness.
