Final answer:
African American women in the 1950s typically wore hairstyles that matched European beauty standards. Beneatha's act of cutting her hair is a bold statement of self-acceptance and a precursor to the 1960s and '70s Black Pride movement, rejecting the imposed White beauty norms.
Step-by-step explanation:
In the 1950s, African American women often wore hairstyles that conformed to European beauty standards, which usually involved straightening their natural hair. The character Asagai in the play A Raisin in the Sun refers to such styles as mutilation because it involves altering one's natural appearance to meet the beauty standards imposed by a dominant culture, which can be seen as a way of denying one's own cultural identity. Beneatha's gesture of cutting her hair in the play is a bold act of self-affirmation and rejection of oppressive beauty norms. By embracing her natural hair, Beneatha is making a strong statement to the outside world about African American self-determination and rejecting White characterizations of beauty. This is a precursor to the widespread expression of Black Pride seen in the 1960s and 1970s.
