Like puppies, heads of hair need to be pampered regularly, or they’ll leave a mess on the couch and act up every time you roll down the car windows. Calm unruly coiffures with today’s Groupon: for $45, you get a haircut, deep-conditioning treatment, and scalp massage (up to a $90 value) at Serenity Hair Lounge in Atlantic Highlands.

Specializing in precision cutting and coloring, Serenity Hair Salon's crack squad of Vidal Sassoon–trained stylists conduct surgical strikes on tufted targets, restoring luster and stability to crisis-ridden coiffures. Each 'do-hewing session starts with a thorough consultation to determine the customer's particular follicular needs. Once vigorous shampooing has removed all foreign matter, such as oil, dirt, and Czech diplomats, human-groomers apply a deep-conditioning treatment. The Aveda product moisturizes and zaps frizz, rendering strands smoother, softer, and healthier. To fully infuse hair with conditioner, Serenity's stylists administer a three-minute massage. Skilled fingertips delicately tap-dance across the scalp, sending a Morse code message of relaxation to the brain. Finally, the salon's ruff-Rodins sculpt and snip follicles into flattering shapes and then mount them atop heads.
