In her 2017 biography "Harry: Life, Loss, and Love”, author Katie Nichol reveals that the prince started to grow his facial when he began his military training, but The Queen disapproved.
And, this isn’t the first time we have heard about her majesty’s opinions on the matter.
A royal insider previously told Hello! Magazine: "The rest of the family liked it and were taking the mickey, especially his cousin Zara who dubbed him Prince Hairy.
“But the Queen soon let her displeasure be known.
“She doesn't mind royal men growing beards when they are away in the armed forces or out in the wild like Harry was in the Antarctic, but she expects them to be clean-shaven when they get home."
Despite granny’s displeasure, it appears that his beard isn’t going away anytime soon – and we like it that way!
