The idiom "let one's hair down" is a commonly used phrase in the English language. It originated in the 19th century and has since become a well-known expression with a specific meaning. While its exact origin is unclear, there are several theories and explanations surrounding its usage.

This phrase is often used to describe a person's relaxation or uninhibited behavior. It is typically used when someone is in a more informal or casual setting and feels comfortable enough to be themselves without worry or restraint. This idiom implies the act of unwinding and releasing any inhibitions or reservations one may have.

One theory suggests that the phrase may have derived from women in the 1800s who would often wear their hair tightly pulled back in an updo during formal occasions and gatherings.

Another possible origin of the idiom may come from the world of dancing.

However, during more energetic or informal dances, they would let their hair down to allow for freer movement. This act of letting one's hair down in a dancing context may have contributed to the idiomatic meaning of relaxation and uninhibited behavior.

Regardless of its exact origin, the idiom "let one's hair down" is widely understood and used in modern times. It has become a versatile phrase that can be applied in various contexts, from informal social gatherings to stressful work environments.
