Chris Rock, a man with two daughters, asks about good hair, as defined by Black Americans, mostly Black women. He visits Bronner Brothers' annual hair convention in Atlanta. He tells us about sodium hydroxide, a toxin used to relax hair. He looks at weaves, and he travels to India where tonsure ceremonies produce much of the hair sold in America. A weave is expensive: he asks who makes the money. We visit salons and barbershops, central to the Black community. Rock asks men if they can touch their mates' hair - no, it's decoration. Various talking heads (many of them women with good hair) comment. It's about self image. Maya Angelou and Tracie Thoms provide perspective.
