Throughout the movie, we are told that Shelley and Sandra left Phil ten years ago, when Phil was in line for his third straight national championship. The current competition is Hair 2000 (and is sometimes called the championships of the year 2000, to confirm that isn't "just" a name), yet when his honors are announced near the end of the movie, we are told he was national champion in 1981 and 1982. For this to be true, Shelley and Sandra must have walked out on him seventeen years ago.

While the male audience members are lined up taking discs for the Men's Freestyle, it is first shown that the real model for Raymond's Hair Studio is number two in line right behind Hair Montage's volunteer.
