  Anomalies in recent observational data indicate that there might be some
"anisotropic hair" generated in an inflation period. To obtain general
information about the effects of this anisotropic hair to inflation models, we
studied anisotropic inflation models that involve one vector and one scalar
using several types of potentials. We determined the general relationship
between the degree of anisotropy and the fraction of the vector and scalar
fields, and concluded that the anisotropies behave independently of the
potentials. We also generalized our study to the case of multi-directional
anisotropies.
