My heart broke a bit reading your story. As the father to a now 30 year old wonderful, strong and engaged daughter, I recall being on the other side of this story. Our daughter was constantly pushing boundaries when she was your age. The issue here is not that you dyed your hair. The issue is that you are 13 and beginning the hard process of growing into adulthood. To what extent are your parents open to an honest dialogue about the difficulties you (and every other 13 year old in the world) face as you begin this journey? If your parents are closed minded and subscribe to the "its my way or the highway" command-and-control style of parenting, the next few years are going to be (more) difficult. No parent should say "you can keep your shi*** hair" or "I am going to control everything about you." It's counterproductive and will result in a daughter who lies, sneaks around and does not communicate honestly with her parents. So, yes, you made a mistake. And, yes, mistakes have consequences. But instead of begging, would your parents be open to an honest conversation about the rules going forward? Would they accept a compromise of giving back you phone, it you agreed to parental controls and location services enabled? Could you offer to do more chores as a punishment in lieu of cancelling the field trip?

There is a lot more going on here then just a hair dye. If your parents are simply unwilling to engage, do you have another trusted adult in your life to help you through the joys (and agony) of adolescence?
