Nappy is Cool too.

The distortion of  the views that people have towards Black women are very prominent when Beneatha chooses to cut her hair off. The narrator describes it as "close-cropped and unstraightened"(Hansberry 80), meaning her hair was short and somewhat curly. Ruth, completely baffled, makes it seem as if it is not normal to have hair like Beneatha's; She made it seem as if Beneatha is not socially acceptable to have hair as she does. Saying "You expect this boy to go out with you with your head all nappy" (Hansberry 80)?  Nappy literally meaning "Afro-textured hair", but, why does nappy have to be a bad thing? George goes say that Beneatha looks "eccentric"(Hansberry 80), saying that she and her hair look abnormal and uncommon, but in a shameful way. 
Africans naturally have curly, kiny, and ziggly types of hair. So to go from having naturally curly hair, to the hair that sprouts from your roots..."naturally"  to be "eccentric" is quite a theory. "How can something that's natural be eccentric"(80)?
(like, there's an entire scale and everything) 
Of course during the 50s and the 60s, Black women were known to have pressed/straightened hair. I know that as both time and society have evolved, Black hair and its societal standards will evolve too, as they have. 

Here's where it gets interesting...

At the start of slavery, to possess Euro-centric features was acceptable, and Black women began to abandon their cornrows, and their fro's to transition into a new do' that wasn't curly, or that did not resemble their original heritage. Which began the assimilation into White or European culture- Which is also exactly what Beneatha is challenging in this altercation between George and Ruth.
