We’re crazy about studs. (Just check out our roundup of all things studs and spikes here.) We’ve added them to our denim, heels, bracelets, and even our nail art. But with Sonia Kashuk Studly Haute Hair Set, $9.99, we can now get that edgy feel with our hair accessories as well. The set includes a studded barrette and four studded hair elastics. And after using these goodies, we have to say, our ponytails, braids, and half-updos never looked so chic … and so badass.
