The barber is male (implied by 'who shaves him').
The barber does not shave himself (that would contradict 'every man who shaves himself is not shaved by the barber')
The barber does not shave (as him being shaved by someone else, or shaving himself would be contradictory to the premise)

Conclusion: The barber does not shave.
But if the barber did not shave, by definition, he would have to shave himself.
