Fast radio bursts (FRBs) are bright extragalactic transients likely produced by magnetars. We study the propagation of FRBs in magnetar winds, assuming that the wind is strongly magnetized and composed of electron-positron pairs. We focused on the regime where the strength parameter of the radio wave, a₀, is larger than unity and the wave frequency, is larger than the Larmor frequency in the background magnetic field, L. We show that strong radio waves with a₀>1 are able to propagate when > a₀ L, as the plasma current is a linear function of the wave electric field. The dispersion relation is independent of the wave strength parameter when > a₀ L. Radio waves could instead be damped when 10^ cm, where the condition > a₀ L is satisfied). Alternatively, the structure of the magnetar wind should be strongly modified during a flare to allow for the escape of FRBs produced at radii R<10^ cm
