“Beauty Shop” is as disappointing as a bad perm.

Queen Latifah stars as Gina (whose introduction in “Barbershop 2: Back in Business” now seems solely made for the spin-off), who has relocated from Chicago to Atlanta to further her daughter Vanessa’s (Paige Hurd) piano lessons at an arts academy. She lives with another single mother and her troublesome daughter Darnelle (Keshia Knight Pulliam).

Gina is stuck working for a tyrannical European salon owner, Jorge (Kevin Bacon), who’s cattier than the salon boss of the TV show “Blow-Out.” Most stylists can’t stand him (maybe it’s that they can’t stand Bacon’s overacting), including country bumpkin Lynn (Alicia Silverstone), who he recognizes only as “shampoo girl.”

Gina’s dream of owning her own shop is realized when Jorge kicks Gina out for letting Lynn cut and style customers’ hair. Gina takes over a dilapidated store on the ghetto side of “Hot”-lanta and manages a team of sassy and sarcastic stylists: Chanel (Golden Brooks) is full of attitude, Ms. Josephine (Alfre Woodard) quotes Maya Angelou poems and the very pregnant Ida (Sherri Shepherd) eats everything.

Lynn now has a chance to be a stylist at Gina’s salon but also has to deal with being picked on for being white, mirroring the situation the white guy faced in “Barbershop.”

Ex-con James (Bryce Wilson) braids hair with the best of them and turns the neighborhood ladies on, but with his “man-bag” and pinkie-lifting-while-drinking-cappuccino habits, he keeps the hairdressers guessing.

Not only are Gina’s hairstylists out of control, but the locals are, too. There’s Catfish Rita (Sheryl Underwood), who makes monkey noises selling monkey bread and meals, and booty-camera-shooting Willie (Little JJ), who harasses Vanessa.

An electrician and the store’s piano-playing neighbor, Joe (Djimon Hounsou), rewires a few troubled circuits for Gina – and possibly rewires her heart.

Despite the chaos in Gina’s shop, her business has a few valuable clients – troubled housewife Terri (Andie MacDowell) and newly breast-augmented Joanne (Mena Suvari).

As things start going well for Gina and company, a turn for the worst happens when Joanne refuses to help Gina with a product deal with Revlon (a shameless Queen Latifah product plug), and Jorge toils to close the shop down.

Don’t let the all-star cast and the big-name talent of “Beauty Shop” fool you – the movie’s humor is amiss, the script is weak and the characters lack substance. “Barbershop” fared well because it had risque wit and humor along with important morals.

The controversial humor in “Beauty Shop”? Bikini waxes. And its moral points? Um, none.

What “Beauty Shop” has is Bille Woodruff, the director responsible for the 2003 flop “Honey.” And it has Bacon and Silverstone doing the worst accents of their careers.

Like a bad haircut, “Beauty Shop” will be forgotten. But unlike a bad haircut, you won’t laugh about it later.
