Before they became a fashionable accessory, feather extensions were used by undercover police to get close to the source of early-morning crowing. Pick up proven plumage with today's Groupon: for $15, you get three feather hair extensions at Salon Flux (a $30 value).

Salon Flux's staff spiffs up strands with traditional and trendy techniques in an intimate salon space. A stylist attaches each trio of avian-inspired tufts with a micro-link bead, which generally remains adhered to the hair for about six weeks. During that time, clients can continue their usual routine of shampooing, styling, or stuffing locks under a bald cap without damaging the extensions. Waiting customers sip on complimentary refreshments as they browse a large selection of magazines or read aloud to excited tresses. Removal of the extensions is complimentary, and though re-attachment is not included in this Groupon, patrons can swing by Salon Flux for a bead re-installation ($5).
