What is the origin of the idiom "crowning glory" and when to use it?

The origin of the idiom "crowning glory" can be traced back to the Bible, specifically to the Book of Corinthians, where it is written: "But if a woman has long hair, it is her glory. For long hair is given to her as a covering." Over time, the phrase has come to refer specifically to a person's hair, and it is often used to describe hair that is particularly beautiful, healthy, or well-styled.
