Is it permissible to accept an invitation and eat from the feast of a man who works as a hairdresser for women?

If all of a man's wealth comes from shaving women, then it is not permissible to eat from his feast (walima). If he has other lawful wealth, then it is disliked to eat from his food. As for attending his invitation, it is not forbidden unless there is a reprehensible act at the place of invitation that cannot be changed, in which case attending becomes forbidden.
