Dr Shahmalak also pointed out there is a 'strong' baldness gene which runs through the Mountbatten-Windsor family.
'It started with Prince Philip and has now been passed down to Prince Charles and on to his sons Prince William and Prince Harry,' he added.
Prince Harry has fortunately enjoyed thicker hair than his older brother, Wills.
The royal was even known for poking fun at William's thinning crown, after the Duke of Cambridge started losing his hair in his 20s.
'I think he definitely is brainier than I am, but we established that at school, along with his baldness,' Harry once said about William.
William recently shaved his hair and debuted a buzz cut last year in a bid to salvage his balding head.
Both Prince Harry and William appear to have inherited their father Prince Charles' balding gene.
During his recent tour to New Zealand, a fan reportedly told Harry 'you look just like your father' to which Harry replied: 'I'm losing my hair like him too'.
