That cannot be true. I have seen too many zombie movies to believe that the entertainment industry would have lied to me all my life

Kangal is right. There is no such thing as a Voodoo zombie. That was a defamatory campaign invented by the European missionaries to suppress traditional faiths and promote Christianity. In fact, the idea of using a person's piece of clothing, hair, blood etc to "cast a spell" and exert control over said person comes from European medieval wichcraft. Nothing to do with Voodoo at all.
