Ice Cube, Cedric the Entertainer, Sean Patrick Thomas, Eve, and several other actors reprise their roles from the first Barbershop film. Barbershop 2 also features what is billed as a "special appearance" by Queen Latifah, who starred in a spin-off, Beauty Shop which was released by MGM in early 2005.
While Calvin attempts to figure out how to deal with the coming threat of direct competition from Quentin's flashy establishment, his barbers have issues of their own. Terri (Eve) is finding success in managing her anger, but not in dealing with her attraction to Ricky (Michael Ealy). Isaac (Troy Garity), the lone white barber, is now the star of the shop, and begins to feel that he deserves star treatment. Jimmy (Sean Patrick Thomas) has quit the shop to work for the local alderman (Robert Wisdom); his replacement, Calvin's cousin-by-marriage Kenard (Kenan Thompson), is fresh out of barber school and horribly inept at cutting hair. With the barbershop and other businesses like it under threat from gentrification, Eddie (Cedric the Entertainer) reminisces several times to his time as a young man in the late 1960s, when he first started working at the shop.
After attempting to change his own barbershop's style and decor to match those of his rival's, Calvin speaks out against the neighborhood's gentrification at the local city council meeting in an attempt to stop the changes in their neighborhood. Unfortunately the council doesn't change their mind and continues the project. But in the end, old customers still come to Calvin's barbershop and remain loyal to the old school style.
