Not necessarily—what would the Polyjuice make you look like? Also, hair in Polyjuice is used at time of use, not at time of brewing, and that may be the difference.
More likely, from what we know in MoR, would be something from a troll. “The troll is unique among magical creatures in continuously maintaining a form of Transfiguration on itself—it is always transforming into its own body”(Ch. 16). Also, rereading that passage, with it’s “Expose them to sunlight” bit, does make the potion Harry brewed in 78 a lot more interesting. It’s probably too obscure to ever come up again, except maybe as a throwaway line about brewing troll repellant for sale, but it’s amusing anyways.
