Corrected entry: Cadets Blanks and Copeland have all their hair shorn off at the police barber because they think that it's like the army. When they discover that it wasn't necessary, both men look quite horrified. Yet over the whole course of training, which took about 12 or 14 weeks, their hair does not grow back even an inch. And it's quite unlikely that they decided to keep it that short since they seemed to like having hair.

Correction: IMHO, it is certainly possible that once they got used to the idea, that they liked it or at least decided to try it out for a while. Many men keep their crewcuts even after leaving the military even though they would never have had a crewcut before.

They were also trying to suck up to Lt. Harris, and he loved their haircuts. They could've kept them for him.
