Abstract: Let $ f$ be univalent in the unit disk $ U$ and continuous in $ U \cup T$, where $ T = \partial U$. We prove that if $ f$ satisfies a Hölder condition, then each point in $ f(T)$ is the image of at most finitely many points on $ T$. The bound for the number of preimages depends in a sharp way on the Hölder exponent.
