We study, within an approximate Inverse Amplitude Method to unitarize Chiral Perturbation Theory, whether low mass scalar mesons can survive in large Nc regime, and show that vector mesons such as ρand K^* survive as narrow width resonances, but all of the scalar meson nonet below 1GeV fade out as Nc becomes large.
