Do you know what L-Cysteine is? It's duck feathers, hog hair, but most of the time, it's human hair. Yup, human hair. That's absolutely disgusting! And Domino's uses that ingredient in their pizza. I refuse to eat their pizza until they fix it, are you with me? L-Cysteine even can have dangerous side effects, and for a good reason! Please sign, and share my petition! Thank you very much!
