Yes, it sounds more like his mother was using him to try and win a law suit.
I've had people complaining about my hair all my life, but I've never deliberately broken any rules. In college one of the women teachers called me into her office to tell me one of the male teachers had complained about my hair as being "unkempt." It was actually as kempt as I could make it. Washed and conditioned every morning, blown dry and then set on large rollers for a while to try and calm it down a little. I wore it long, mid back, and parted in the middle like many of the other girls but it has a natural frizzy quality many people hate.
One of my first jobs was as a waitress. I wore it skinned back in a bun, but when I stood in the light you could still see a halo of frizz and my boss complained about it. Other than taking a tip from Alfalfa and slicking it down with a handful of lard there's nothing I can do about it.
The last time anyone made a big issue over it was in the mid eighties when my date and I were walking through the mall with another couple. Suddenly the other man suddenly stopped, turned around , put his hands on my hair and pulled it back asking if I couldn't brush it or something. The more I brush it the more electricity and the wilder it gets.
Women I know are always recommending conditioners to me.
So I understand how the boy feels when people seem to want his hair to be a completely different texture, but length is something we can control, and if it's part of the rules we have to conform if we want to stay.
Hair like mine, as kempt as it's going to get:
