A bobby pin may be a common hair accessory, but it goes by many different names! In the UK, they are often called hair grips or hair slides. They can also be called hairpins or clips. Some people may refer to them as hairclips or styling pins. The word "kirby" is also commonly used in the UK to describe bobby pins, after the company that first started selling them. No matter what you call them, bobby pins are a small but essential tool for keeping hair in place, whether you are simply fixing a stray strand or creating an intricate updo.
