Negroids have a very different hair type then whites , black hair is referring to there hair type and how they manage/take care of it because its different then ours .
What are you trying to say about black people hair?
I think they just have different hair type and I have a theory that there hair type is more animal like, not clean. I do not mean inferior like humans are but more wild like animals
Blacks being associated with animals has a long history in the world and it is hurtful to be thought of as less than human. You would not like it if people implied that you were less human based on your skin color.
