For many Black women, the hair salon is a cultural safe space, where stories and secrets help build an intimate community. In SpeakEasy Stage’s production of the Tony-winning play, “Jaja’s African Hair Braiding,” the West African immigrants who do the braiding and the customers seeking their services come together in a funny play that also explores serious current-day immigration policies. Three members of the cast and crew join Callie to talk more about the production.
