Today's Idiom
Let one’s hair down
Meaning: To relax or behave in an uninhibited manner.
Origin: This phrase was first reference in John Cotgrave’s, The English Treasury of Wit and Language published in 1655. During the 17th century, women were obliged to wear elegant hair-dos that were normally pinned up. It was only during brushing or washing that their hair was let down. The term used for this at the time was dishevelling. Today, the term dishevelled refers to someone who is untidy, however back then it applied specifically to hair which was unpinned.
