Yes, but only to an extent. There are no (to the best of my knowledge) actually blond arabs (though hair dye is a dime a dozen these days, of course). And Semites can generally be readily identified by certain features that while they can be shared with Caucasians are rarely not present on Arabs (bridge of the nose, the brow, the eye placement, etc.).

Race is determined by genes, not looks. There are, AFAIR, only five human races and arabs, being semites, belong to one of those called "europoids" (aka "caucasians").
