Unlike bad boys, bad heads of hair aren't secretly considered attractive by straight-laced schoolgirls. Broaden your appeal with today's Groupon: for $45, you get a deep-conditioning treatment and either a partial highlight or a single-application color, done by Aura Andrew at Hair Ink Salon and Tattoo Studio (a $140 value).

Hair Ink stylist Aura Andrew uses quality salon products and multistep services to imbue lackluster locks with vitality. Aura begins with a deep-conditioning hair-repair treatment, employing professional Joico K-PAK hair love potions to rekindle romance with newly shimmering manes. The treatment obliterates toxins and the build up of residue from lesser products, then apprentices hair in the art of pH and porosity balance. Keratin proteins reconstruct shabby strands more effectively than gluing them back together, and moisture recovery seals in hair's color and lusciousness. The pair of treatments usually takes a 1.5–2 hours, depending on the hair's length, thickness, and chattiness. Aura also invites hair wearers to divulge their deepest color-based desires. Clients can choose to selectively illumine hair with partial highlights or dye every last head fiber with a single-application color.
