Should I mind about what people think of me?

Hi my name is Jade and I'm a 15 year old girl of mixed race. For the first time I let my hair go natural and I really like it. But my hair is something that you don't see everyday (it's really big and curly). But sometimes when I walk on the street people stare at me and laugh and that makes me sad because I always mind about what other people think about me.
