Beauty Shop (2005)

Beauty Shop ~ Queen Latifah, Alicia Silverstone, Djimon Hounsou, and Lil J

Plot
You thought you'd heard it all in the barbershop, but you haven't heard anything yet - the women get their own chance to shampoo, shine, and speak their minds in Beauty Shop. From the filmmakers that brought you Barbershop and Barbershop 2, Queen Latifah stars as Gina, a hairstylist who opens a shop of her own.
