Running all over town to maintain your beauty routine makes you want to tear your hair out. (Almost. You did spend $300 on those so-called natural highlights.)

Simplify the madness at The Barber Lounge, über-stylist Greg Griffin’s huge new salon/spa/barbershop loft, which has its grand opening tomorrow in SoMa.

This place is beauty central. Men get groomed (mustache trims, hot-towel shaves) at the old-timey barber station outfitted with 1930s leather chairs and a vintage red, white, and blue pole. Ladies head to the mod side area for head-to-toe primps.

Frequent fliers of both sexes should go for the Jet Set Prep package: wax, body polish, nails, spray tan. The simpler Pre-Party Fix includes mani/pedi, blow out, and makeup (for her) or shave and dry cut (for him).

And don’t miss the wall of hair: a mini gallery devoted to famous coifs like Cindy Crawford and Diana Ross.

Okay, so it’s not exactly art. But why split hairs?

The Barber Lounge, 854 Folsom Street, between 4th and 5th Streets (415-934-0411 or barberlounge.com).
