Assalamu alaykum,
Definitely, within the Jewish and Christian religions hijab is actually highly recommended, if not prescribed as compulsory, for women. And you only need to look at the Christian depictions of Mary, the way her hair is veiled or the very flowing jilbab-like robes that nuns wear, to see covering the hair is associated with piety and modesty.
And historically, women in Europe from upper-class or noble families would completely veil themselves outside of the home, sometimes including a face veil.
It's just ironic that on the one hand it is considered to be a symbol of purity and yet when it's associated with Islam it's shouted down as backward.
