In this letter we investigate whether the isotropy problem is naturally solved in inflationary cosmologies inspired by string theory, so called pre-big-bang cosmologies. We find that, in contrast to what happens in the more common 'potential inflation' models, initial anisotropies do not decay during pre-big-bang inflation.

Conformally related early universe models can be told apart by the location of frame-invariant variables built from the time variation of particle and Planck masses.
