a clip (= an object for fastening things together or holding them in position) for hair, usually made of plastic, with two curved parts with large curved teeth (= rows of points) that are held together in the middle by a hinge with two parts that can be pressed together to open the clip

A hair claw is a good alternative to an elastic, which can cause hair breakage. 皮筋会导致头发断裂，发夹是一个不错的替代选择。

Claw clips were everywhere in the 1990s and now they're back.
