  We calculate multicomponent line-driven wind models of stars at extremely low
metallicity suitable for massive first generation stars. For most of the models
we find that the multicomponent wind nature is not important for either wind
dynamics or for wind temperature stratification. However, for stars with the
lowest metallicities we find that multicomponent effects influence the wind
structure. These effects range from pure heating to possible fallback of the
nonabsorbing wind component. We present a simple formula for the calculation of
metallicity for which the multicomponent effects become important. We show that
the importance of the multicomponent nature of winds of low metallicity stars
is characterised not only by the low density of driving ions, but also by lower
mass-loss rate.
