The Origin and History
Like many English idioms, this expression has an interesting historical background.
Centuries ago, women often kept their hair tied up or covered in public because loose hair was considered informal. At home, after completing daily duties, they would remove hairpins and allow their hair to fall naturally.
Over time, this physical action became a metaphor for relaxing and becoming comfortable.
Eventually, the phrase evolved into an idiom meaning:
- Stop being formal
- Relax completely
- Enjoy yourself freely
Today, people of every gender use the expression, even though its historical roots involve women’s hairstyles.
