I can’t wear my hood at school anymore

This has always been a rule but they didn’t care. Now they care. Teachers don’t really care but the principal and other higher up staff are always roaming the hallways or always stand in the hallway when switching. I hate how I look and my hair is horrible. I have the worst face and hair of all time. I hate all hairstyles on me I’ve tried so many. “You have an egg shaped head” has stuck to me for a while. That was 4 years ago. They tell me at least 3-5 times a day to take my hood down and I just say I will in a second and they are getting tired of that excuse. I’m not taking my hood down in school it’s so embarrassing and I don’t feel comfortable without it. What can I do or am I just gonna take the consequences
