This is something to get into a lather about: Pojo soaps have created a werewolf repelling soap. If you’re more concerned about something sucking your blood rather than ripping you apart, they also do an anti-vampire soap, as well as one to keep the zombies away.
If you are actually fond of werewolves, Sundance Soapery have created a soap that will have you smelling like a lycanthrope. Slightly more disturbing is this Vampire Whitening soap which promises to make you as pale as a vampire.
