read that. it reminds me again why hair matters. joining me today, nicole arie-parker, leading actress on streetcar named desire which i have seen twice and have tickets for a third time. and anthea butler, professor of religious studies and graduate chair of religion at university of pennsylvania. joan morgan returning to nerdland. author of when chicken heads come home to roost. and nikki walton, founder of curly niki.com and author of better than good hair. thank you, all, for being here. and for and for being throng have this conversation. for me, black women s hair, the politics of it, seem obvious. but i realize that it may not be obvious to everyone, particularly maybe to our viewers who haven t encountered these questions before. help me make the case for why black hair matters?
