We get the whole history of Black hair in Africa and beyond, with portraits of hairstyles through the years, and advertisements for Black hair products. We get interviews with tons of men and women about their hair and the implications of wanting “good” hair, hair that’s straight and smooth. We get the story of politics in Black hairstyles. And there’s a chapter in here that’s basically a letter to White people about Black hair and hair routines, and it is perfect.
