Ah Bia, parenting the hair with Wysteria is easy :) It is NOT conforming though, so that does not do it. Select the hair, then from the bottom dropdown menu, select "body". Then go up to "object" and select "properties". In the properties popup box, select Parent, and then parent the hair to Wysteria's head :) Or another character's head. However, in the default scenes that came with her, it is already parented :)
