From the article: “My book on the symbolism of dreadlocks in Yorubaland tries to explain what knotted hair means to Yoruba people, and where these ideas come from. Numbering around 40 million, Yoruba people predominantly occupy southwestern Nigeria. In West Africa, they are found in Benin Republic, Ghana, Togo, Sierra Leone, and Liberia. In the diaspora, they are significantly present in the US, Brazil, Cuba, Haiti and the Caribbean. … A popular phrase used by Yoruba people to describe dreadlocks is “a crazy person’s hair”. The language also has an idiom that shows how people feel about madness. A person will ask, “kini ogun were?” (what is the cure for madness?) and get the response, “egba ni ogun were” (whip is the cure for madness).”
