Not exactly. It is a very common expression. Learners still need it because native speakers use it all the time, and it appears beside real idioms in most party vocabulary lists.

Is “Let Your Hair Down” Old-Fashioned?

A little, yes, but it is still common and easy to understand. It sounds natural in casual conversation, especially when you mean relaxing after stress or rules.

Is “Party Animal” Positive Or Negative?

It depends on tone. It can sound fun and positive, but it can also suggest that someone parties too much. Context does the heavy lifting, as usual.
