Abstract: Present invention relates to a hair clip that mainly comprises: a base plate and an upper clip plate. Multiple equally spaced curved strips are equipped along the length of base plate. Such curved strips further form multiple rooms on base plate. Application of present invention allows hairs to be distributed evenly within the rooms and clips hairs firmly between upper clip plate and base plate to prevent hairs from distortion and damage. In addition, by eliminating middle clip plate the production cost is lowered.
