lets one's hair down

Drops the formality

To let one's hair down is to relax and behave freely, dropping usual restraints or formality.

The image is of someone releasing pinned-up hair at the end of a formal occasion: After the conference ended, we went to a bar and really let our hair down.

The phrase suggests a shift from public composure to private ease.
