We provide linear lower bounds for $f_
ho(L)$, the smallest integer so that every curve on a fixed hyperbolic surface $(S,
ho)$ of length at most $L$ lifts to a simple curve on a cover of degree at most $f_
ho(L)$. This bound is independent of hyperbolic structure $
ho$, and improves on a recent bound of Gupta-Kapovich. When $(S,
ho)$ is without punctures, using work of Patel we conclude asymptotically linear growth of $f_
ho$. When $(S,
ho)$ has a puncture, we obtain exponential lower bounds for $f_
ho$.
