Yes, that was considered the "German way" In the "Neger Neger schornsteinfeger" book i just finished reading, the guy talks about how the boys would "try" and let their hair grow long..but always would get caught out by a HJ patrol who would be going around the clubs, Dancing halls etc looking for HJ lads with too long hair, then take them outside and cut their hair straight away.. reminds me of my school days.. thats the only way we really had to rebel as well, but trying to let the hair grow just a bit longer than was allowed.
