Why do you think schools suspend students for violating the dress code for the way they wear their hair when hair does not have anything to do with how someone dresses?

FACT: The authorities are ignorant, bigoted a**holes who don't know the meaning of logical thinking. I was more logical than that lot when I was in primary school.

In my school we did not suspend students for dress code violations. We gave them a stern warning and an in-school suspension for a second violation. We didn't care about hair styles.

All in all...your just another brick in the wall.

When I was in middle school, it was against the rules for students to have any "unnatural" hair colors. A group of my friends and I all dyed our hair, thinking they wouldn't suspend us all... there were probably 20 of us who showed up on the same day with green or blue hair. Sure enough, they did. I was one of the lucky ones in that mine was washable and the principal gave me the option of washing it out and just getting a two-day in-school suspension or going home for at least a week. 

Despite the fact that I was a royal pain in the rear as a teen, the principal indulged me and he and I had a lengthy discussion about the policy and why it existed. He said it was because the colored hair was a distraction in class... that people were focusing on the hair and not the lesson. In some situations, it was people talking about how awesome the color was. In others, the kids were getting bullied and picked on for being "freaks" or "punks" or whatever. I asked him if bluejeans all of a sudden became a different thing for kids to wear, if he would ban jeans at school. He said he would. In my infinite teen wisdom, I knew the the argument was over. The guy had clearly lost his mind. Banning blue jeans. lol But, as an adult, I get it. Kids need to be focusing on the lesson, not talking about other students, not causing an uproar. Classes are only 50 minutes long. If a teacher loses only five minutes to hulabaloo about hair, the kids have missed out on 10% of their instruction time... over hair. That is ridiculous. 

My school had a length for skirts/dresses/shorts also for sleeves..
Hair was only mentioned in that the hair styles were not allowed to be a distraction to the class. My kids school will send kids home for dress code violations. If a student is not appropriately covered they will not be allowed in class. I personally think they should keep some really ugly moo-moos and make them wear them to class and not be allowed to change even if Mom and Dad bring clothes.

No...hair should not be considrered part of the dress code.  Hair is physically part of a person while clothing is an acessory.

In my High School, denom and blue jeans were strictly forbidden. Hair style was never a consideration for code, but it didn't stop teachers and such from commenting on it.

Fact: Schools set dress codes which are implemented with their school policies. Included are tattoos that can be seen, earrings for boys, hair color or style that is considered distractive to the learning environment.

Girls: no see-through blouses, dress length, etc.

Policies are set by the school board of the school district. Parents who question policies can take complaints to board meetings.

Dress codes and school policies are given to students at the beginning of the year. Parents have to sign an agreement on the first week of school. Consequences for breaking rules are also given.

All in all my what is just another brick in the wall? That can't be the Pink Floyd song you are referring to, because when you insert the missing word(s) it would not fit in with the tune.

It has everything to do with it. 

Who cares if you are in uniform if you have a Mohawk reaching to heaven dyed bright fuschia.  THINK WOMAN.   Also heavy weird makeup and tattoos speak volumes regarding your ability to be a professional person who knows how to  use good judgment when realizing how you are perceived by others. 

Or not.  Go to another school.     There are plenty of schools, I'm sure you can find one that is "progressive" and lets you look like a screaming idiot if you choose.
