WHY: To detox the liver and help with hangovers.
 

HOW: You may not want charcoal in your stocking, but you do want it in your glass. Relied on since antiquity as a purifier, charcoal has shown up in skin care — it’s an ideal vehicle for drawing out impurities — and, more recently, in beverages. Juice Served Here in L.A. was one of the first to serve up charcoal lemonade, and New York’s Juice Generation blends it into an activated greens juice and a creamy raw almond and hemp-milk protein smoothie — all will help detox from the inside out.

WHY: To take charge of your eating habits. 

HOW: Add these four new books to your home library for guidance: Wellness guru Dr. Frank Lipman’s The New Health Rules (Artisan) offers simple and effective advice for rebooting your lifestyle in and out of the kitchen, Martha Stewart’s Clean Slate (Clarkson Potter) takes her signature straightforward and streamlined approach to recipe-writing and applies it to clean cuisine, Amy Chaplin’s At Home in the Whole Foods Kitchen (Roost Books) is essential reading for veggie-forward cooking and Paul Pitchford’s Healing With Whole Foods (North Atlantic Books) offers a helpful overview of Eastern medicine’s approach to nutrition. 

WHY: To ward off ill health. 

 HOW: “Leafy greens are detoxifying, energizing, hydrating and loaded with fiber, vitamins, minerals and phytochemicals,” explains Dr. Lipman Be Well health coach Jackie Damboragian. “They give your body the artillery it needs to fight off potential heart disease and cancer. One way to boost your leafy-green intake is to add them to your breakfast; sauté some spinach with eggs, or add a green powder to your smoothie. The more greens you have, the more likely you are to crowd out the bad stuff such as sugar and processed food, which will help you get and stay on track!”

WHY: To soothe and revive tired skin. 

 HOW: “To make your own detox mask, mash a ruby red grapefruit and mix with cooled, cooked oatmeal and one cup of milk,” says Joanna Vargas, facialist and founder of Joanna Vargas Salon and skin-care collection. “This treatment is loaded with antioxidants, and the grapefruit helps purge all of the toxins so you can renew your skin. Oatmeal is super soothing, packed with vital minerals to help replenish skin, and it calms any inflammation caused after a night of drinking and prevents breakouts. The milk is dual purpose: It exfoliates with lactic acid, and it's also soothing for the skin cells.”

WHY: To kick-start your digestive system. 

HOW: “Probiotics are important when it comes to intestinal integrity, and prebiotics help establish a proper environment for them to thrive,” explains Jelena Nikolajevic of New York’s Mainstay Acupuncture. “Include fermented foods like sauerkraut, kefir, yogurt, kombucha and beet kvass in your diet. The healthy bacteria found in them will balance the flora and fauna in the gut and reflect its benefits through the skin.” 

WHY: To rejuvenate lackluster strands.   

 HOW: Constant heat styling and product overload can do a number on even the healthiest manes. Paul Labrecque in New York is the latest salon that literally gets to the root of the problem, giving your hair and, perhaps more important, your scalp a serious spa treatment. The new C-Zen Scalp Massage couples a blend of nourishing citrus oils with a glorious deep scalp (and neck!) massage, followed by a 30-minute revitalizing mask, to reboot your scalp health and address split ends and breakage.

WHY: To turn back the clock. 

HOW: “Take fat-soluble vitamins like E and D to help maintain skin’s elasticity and suppleness,” says Nikolajevic. “Avocados, sardines, fish oil, coconut oil, wheat germ, olive oil, whole non-pasteurized milk, clarified butter ghee: all contain essential fatty acids that are beneficial for skin.”
