i don't think so, albeit the shampoo is a freebie that probably costed the donator in the realm of, say, 99 cents.
it is, however, an animal-tested hair detergent, so the souls of thousands of little wild-eyed mammals could in fact commence their phantasmal rutting (it is spring, after all) right set amongst the stubble-y roots of whatever sits atop my scalp.
i was also thinking chemical attack or a dirty hair clipper.
