Safety is absolutely the number 1 concern! I have only been involved in girls lacrosse for the last 8 years from youth through division 1. IMHO the girls that wear helmets are clearly more reckless with their sticks. I don't think it's intentional, but just wearing a helmet removes a sense of vulnerability that pushes girls to obey the rules. The rules need to be enforced and quicker yellow and red cards are not being called Most of the issues come from just a few girls and they have to change their ways or be removed from the games to protect the other girls and the betterment of the game.
