A barrette (American English), also known as a hair clasp (British English), or a hair clip, is a clasp for holding hair in place.
They are often made from metal, a clasp is used to secure the barrette in place, the clasp opens when the two metal pieces at either side are pressed together.
Barrettes are worn in several different ways partly according to their size, with small ones often used at the front and large ones in the back to hold more hair.
They are used to keep hair out of the eyes, or to secure a bun, French twist, or ponytail.
Short metal "clip" barrettes are sometimes used to pull back front pieces of hair. Barrettes are also sometimes used purely for decorative purposes
