Aside from warming our brains and framing our faces, hair provides the only concrete evidence of the existence of wind. Treat breeze detectors right with today’s Groupon: for $40, you get $100 worth of salon services at Bäkerloo Salon & Gallery in Carlsbad.

Bäkerloo Salon & Gallery, voted a Top Business in 2010 by readers of the North County Times, employs a team of accomplished stylists to beautify hair with a bevy of services. Professional mane tamers, trained at top-rate institutions such as Toni & Guy, Unite, and Vidal Sassoon, wield scissors and razors to snip men's ($25+) and women's ($50+) tresses. Don a new hue for full-head color ($75+) in shades such as sunny blond or ravishing red, or procure a sculpted updo ($65+) for an upcoming cowbell recital. A gentle keratin treatment ($200+) straightens and defrizzes follicles, and a customized set of feather extensions ($25–$35 per extension, which includes 2–5 feathers each) dresses up bland strands and attracts the wolf whistles of approving songbirds. During a lock-lopping session, guests can sip complimentary wine and coffee or admire the rotating showcase of local and macaroni art that adorns Bäkerloo's walls.
