What your hair color says about your health

Our hair is our most noticeable trait—and we obsess over it accordingly. But even though we spend lots of time enhancing and re-enhancing our tresses, we probably haven't considered something pretty cool: What's underneath all the glosses and highlights can be a health barometer of sorts.

If You're a Blonde...

Protect Your Peepers
Women have a higher risk than men of developing age-related macular degeneration (AMD), an eye condition that can cause blindness. And fair-haired females are especially prone to AMD, says Dr. Svetlana Kogan, founder of Doctors at Trump Place in New York City. A diet rich in the natural compounds lutein and zeaxanthin—found in kale, spinach, and snow peas—can help fend it off. Kogan suggests munching on one cup of the green veggies every day. (As the days grow shorter, salads tend to slip off the menu but they’re a great way to get the veggies you need. Try these 4 Hearty Winter Salad Recipes.)

Cover Up
Melanin gives skin its color and helps shield it from harmful UV rays, says dermatologist Dr. Joel Schlessinger, president emeritus of the American Society of Cosmetic Dermatology and Aesthetic Surgery. Thing is, blondes produce less of the stuff, which leaves their skin (and especially their scalps) at a higher risk for melanoma. Buy a full-spectrum SPF 30 sunscreen that shields against harmful UVA and UVB rays. And don't neglect your head: "Blondes should always wear a hat when they're in direct sunlight," says Schlessinger.

If You're a Brunette…

Hold On to Your Hair
More than half of the 30 million American women with visible hair loss are brunettes. That could be because they have less hair to begin with: "Brown tresses are generally coarser and thicker than blonde or red strands, and your body produces fewer of them," Schlessinger says. So when brown hair follicles die, they leave behind more noticeable thin patches. Stave off sparse coverage by eating right. Low iron can contribute to hair loss, so start swallowing 18 milligrams a day; one cup of fortified oatmeal will provide your daily fill. (Oats don’t have to be boring—you can add eggs and cheese, berries and yogurt, and more. Try one of these 5 Delicious Oatmeal Recipes.)

Stub Out That Butt
Your chestnut mane is the result of lots of melanin, which could fast-track your dependency on nicotine. The reason: Melanin prevents your liver from quickly metabolizing the drug, and the longer it's in your system, the faster you become hooked. Animal studies suggest that vitamin C helps keep your liver in top shape. Swallow 75 milligrams a day in the form of half a cup of red peppers or a medium-size orange. Your best bet, though, is never to pick up a cancer stick. Period.

Snag a Boyfriend
Do gentlemen really prefer blondes? Nope, according to Florida State University research. Not when it comes to long-term relationships. Plus, according to a 3,000-person survey, men prefer brunettes as serious mates because they see them as more reliable and steady. If you're not looking for a long-term thing, try a little spontaneity: Make the first move by slipping that cute guy your digits.

If You're a Redhead...

Watch Your Mouth!
The next time Lindsay Lohan goes in for a cavity filling, she might want to ask for extra Novocain. Fiery locks, it turns out, stem from an inherited DNA mutation that also makes redheads resistant to general and local anesthetics, says Dr. Daniel Sessler, an anesthesiologist at the Cleveland Clinic. In fact, carrot tops may need up to 20 percent more numbing juice than blondes or brunettes. But don't let a little hurt keep you from getting good oral care: Talk to your dentist about pain management prior to plopping down in her chair, or take 500 milligrams of ibuprofen one hour before the appointment.

Look Out for Parkinson's
A recent Harvard study found that redheads have an almost 90 percent greater chance of developing the disease. Why? Possibly because of that same gene mutation: It influences another type of gene that, when also mutated, can be associated with Parkinson's. On the plus side, research shows that folic acid might delay the progression of the illness. Dr. Margaret Lewin, medical director of Cinergy Health, advises taking 400 micrograms a day (more if you're pregnant). A multivitamin has all the folic acid most women need.

Stock Up on Condoms
Redheads make red-hot lovers, or so the stereotype goes. One thing's for sure: They get a lot more action, according to one study. This might be due to a self-fulfilling prophecy, says Kogan. "Red is associated with fire, and fire is associated with passion," she says. "Often, you become what people expect of you." Something others are eager to try: Recent Clairol research shows nearly 40 percent of people said they'd go scarlet for a day if they could.  (Are you ready to try a fiery hue?
