You’ve probably heard someone say let your hair down, and it actually has real historical roots. Back in the 17th century, women, especially those from high society, were expected to keep up fancy, elaborate hairstyles whenever out in public. Once they got home, they could finally be themselves, literally stepping out of the spotlight into a space of comfort and freedom.
