  In the context of the dark energy scenario, the Einstein Yang-Mills Higgs
model in the SO(3) representation was studied for the first time by M. Rinaldi
(see JCAP 1510, 023 (2015)) in a homogeneous and isotropic spacetime. We
revisit this model, finding in particular that the interaction between the
Higgs field and the gauge fields generates contributions to the momentum
density, anisotropic stress and pressures, thus making the model inconsistent
with the assumed background. We instead consider a homogeneous but anisotropic
Bianchi-I space-time background in this paper and analyze the corresponding
dynamical behaviour of the system. We find that the only attractor point
corresponds to an isotropic accelerated expansion dominated by the Higgs
potential. However, the model predicts non-negligible anisotropic shear
contributions nowadays, i.e. the current Universe can have hair although it
will loose it in the future. We investigate the evolution of the equation of
state for dark energy and highlight some possible consequences of its behaviour
related to the process of large-scale structure formation. As a supplement, we
propose the "Higgs triad" as a possibility to make the Einstein Yang-Mills
Higgs model be consistent with a homogeneous and isotropic spacetime.
