You sang the body electric. You even busted leg warmers for the second go around. But you swore you’d never again chirp the praises of a curly perm. We’re still betting you’ll get jazzed for Unga Hair Salon’s ionic “digital” perm service. Treatments at the Gateway Plaza salon go something like this: 1. Have wet hair set with curling rods, which get clipped to a negative ion hub. 2. Sit for one hour or so in Medusa-like limbo while rollers heat up and ionize. Cool for fifteen minutes. 3. Apply neutralizer. Wash out. 4. Fling about formerly stick-straight, chemically virgin hair in throws of permanently bodacious, bed-headed ecstasy. It’s anything but a blast from the past. It might even be the wave of the future. Photo: pudgeefeet / Flickr Available at Unga Hair Salon, 5745 Buford Highway, suite 103, Doraville (770-451-8801).
