It depends on what you are trying to say. If you mean that the person is crazy or insane on one issue, but usually a normal person, it would be proper to say, "estás loco". If you mean that the person is psychotic or should be institutionalized, it would be proper to say, "eres loco".
Una loca is a Spanish equivalent of the English phrase "a crazy woman." The feminine singular phrase also translates as "one crazy woman" in English. The pronunciation will be "OO-na LO-ca" in Uruguayan Spanish.
