My sister has black people hair! She has to use colored people shampoo! I feel so bad for her, like all her friends have pretty straight blond hair and she has like, an afro!
Oh dear, I wonder what would your sister say if she was here right now? It sounds so insulting.
She would probably be laughing because she doesn't really care.
Just because black people have curly and darker hair doesn't make it ugly. It's all in the eyes of the beholder. Not everyone will laugh at that remark, some people are more sensitive so watch what you speak out.
