King Charles has been letting his hair grow longer, said a report in Daily Mail.
"Perhaps he could cultivate a beard as well," the publication wrote in a report based on a throwback picture of the monarch that was shared by the daughter of music legend Johnny Cash.
In the photo taken in 1976, Charles is seen sporting a beard.
Charles became the King of England after the death of Queen Elizabeth.
The Queen was buried with her husband Prince Philip who died last year at the age of 99.
