Having frizzy, unkempt hair can make you appear disoriented and unhinged during job interviews, first dates, and shouting matches with the neighbor's bush. Keep it together with today's Groupon: for $149 you get a Keratin Complex smoothing treatment at Prestige Salon & Spa in Plymouth (a $299 value).

The expert tress tamers at Prestige Salon & Spa discipline insolent manes with the Keratin Complex smoothing treatment designed to combat frizz and unlock lost luster from all hair types. The two- to three-hour treatment steeps strands in a protein complex to improve follicular strength, reduce up to 95% of frizz, and render strands shinier and silkier than ’80s parachute pants. Each keratin treatment diminishes blow-drying time and prevents frizzy follies for 3–5 months, though clients should use a sodium chloride–free and sulfate-free shampoo and conditioner for best results. Throughout the coiffure revamp, guests can relax amid the calming orange glow resonating from Prestige’s slick wooden floors and tangerine-hued walls. Cushy black chairs gift visitors a snug seat to witness their ’do redo, and decorative foliage grants ample hiding spots for covert pompadours.
