Dyed Hair at School

Dress codes and uniforms can help reduce the potential for conflict by;
1. Reducing conflict stemming from socio-economic status, i.e., conflicts stemming from comments and personal attacks about who has better clothing and so on.
2. Reducing ways in which gang members can identify themselves which, in essence, is a form of intimidation and creates fear.
3. Reduces the risk of students being robbed to and from school, or for that matter in school, of expensive clothing, jewelry, etc.
4. In the case of uniforms, could help school administrators identify non-students, trespassers, and other visitors in the hallways who stand out in the crowd.

These are general observations and, of course, there are exceptions. For example, one group of students told us that although they had uniforms, the school policy did not specify specific types of uniforms, so some students wore very expensive dark pants and light shirts, while others wore less expensive ones, and the status reduction argument was thus moot. Of course, there are also many ways for gang members to identify themselves in addition to dress, too, so uniforms do not eliminate gangs or all of their ways to identify. Still, the fact that there are some glitches and ways to beat the system should not shoot down the entire concept.

Student and parent input should be received on the front-end of implementing such policies, especially school uniforms. Anecdotal information suggests that such involvement reduces non-compliance and increases ownership into the program. Ironically, once implemented, many students and staff are pleased with uniforms, for example, and parents are also pleased with the idea that they are often cheaper than common popular clothing, plus they do not have the hassle with their children each day of dealing with "what to wear" to school.
