Are you talking about the strand size or the feel of the hair? A lot of misinformed people will call kinky or any hair that isn't straight, coarse. They're referring to the look of the hair. My hair is very soft but medium-coarse and acts like coarse hair. On NC, coarse refers to the size of the strand. My strands look like sewing thread.
3b/c, medium-coarse, low porosity, high density
