What does it mean when you say 'her hair is down'?
Thank you for your help in advance.

I'd say it means she is wearing her hair open, without any bands or slide.
I also saw the phrase "letting her hair down" mean to become more open, to unwind.
Depending upon the context, "her hair is down" could mean she is wearing it loose and naturally flowing, like this, as opposed to wearing it "up," like this.
Also, as mentioned upthread, when someone "lets her hair down," it means that she is acting in a very relaxed (or even somewhat wild) manner. "After three cocktails, she really let her hair down. She was up on stage singing karaoke and dancing like Beyonce!"
It's what happen when I translate word by word.
Thanks for your explanation, it's seem to me clearer (maybe more clear it's better, I don't sorry).
Have a nice and sunny day.
Yeah, what ouisch said. The verb 'is' sounds unusual to me. I've only met 'hair down' in collocation with the verbs 'wear' and 'let'. 'Wearing ones hair down' is something usually reserved for the fairer sex (except in a different sense of 'wear down'; I've worn mine down so much that I'm nearly bald).
[Before the party]: 'Do you think I should wear my hair up for this date'?'/'No - if you've got it flaunt it: I'd wear it down if I were you.'
[Later that night:] 'Don't be such a party-pooper. Why not let your hair down for a change?' [Note, this has nothing to do with hair styles.]
