I have a little sister with hair that sounds like yours. She got lighter brown highlights on the top and colored her bangs the same light brown. Red sounds awesome. Maybe try dying the underside of your hair? Ive seen it on a few people and it looked super cute.I have dark brown hair that is medium length. what are some good highlighting ideas?
