You are right about Lex - though apparently Rosenbaum got sick of playing him towards the end, which is why Season 7 has sort of a half-hearted ending...
Actually my understanding was that he was afraid that the constant shaving of his head would permanently affect his hair. Plus the half-hearted ending was to do with the writer's strike. Most series only got half a season written before the strike. SV was nearly complete with episodes so they are only short by 2 or 3 that season.
