so I straightened my hair and today in class my classmate says

Friend- I like your hair.
Me- Thanks, I don't really like to wear it this way because my scalp itches like crazy.
Friends- Oh because the chemicals right?
Me- Huh?
Friend- To straighten your hair, the chemicals.
Me- I don't use those.
Friend- (Incredulous look) oh.

Don't know if I should be offended or not. Why does the majority of people who are other races girls assume that we have to use chemicals to get our hair straight. My hair goes BONE straight from curly with one pass of the comb.
