A device for clamping thick, textured, coiled or kinky hair includes first and second curved components, each with an outer edge and an inner concave curved edge between first and second ends. The inner concave edges include a plurality of inwardly directed, spaced-apart teeth. A hinge joins the first ends of the curved components, enabling the second ends of the components to open and close around a bundle of hair with the teeth penetrating into the bundle. A cooperating closure maintains the device in position around the bundle of hair. The ends of the teeth define an opening even when the device is closed around the bundle of hair. The first and second curved components are preferably integrally formed from molded plastic. The cooperating closure may include first and second hook shapes. The device may come in different sizes to accommodate different hair textures and styles of children and adults.
