Better-looking hair can start at your next meal. "Just like every other part of your body, the cells and processes that support strong, vibrant hair depend on a balanced diet," says New York nutritionist Lisa Drayer, MA, RD, author of The Beauty Diet. It can take longer to notice changes (both good or bad!) in your hair than in your skin. For example, "just one week with a poor diet can yield acne flare-ups or dry, sallow skin within days," says New York City dermatologist Cybele Fishman, MD, "but with hair, it can take a few months for a nutritional deficiency or the effects of a crash diet to show up." The nutrients you eat today help fortify the hair follicle -- from which each strand is born -- and the scalp that surrounds it. "Healthier follicles? Healthier hair. Healthier scalp? Healthier hair!" Drayer says. Of course, there's more to your hair than what you eat. Smoking, hormonal imbalances, and not enough sleep can also affect how your hair looks and feels. No magic nutrient can make up for those concerns. Still, you have a lot more leverage than you might think. If you eat a balanced, varied, protein-rich diet that focuses on the following 10 foods, you'll be giving your hair the TLC it needs and deserves.
Besides being rich in protein and vitamin D (both are key to strong hair) the omega-3 fatty acids found in this tasty cold-water fish are the true superstar. Your body can't make those fatty acids, which your body needs to grow hair. About 3% of the hair shaft is make up of these fatty acids, Drayer says. Omega-3s are also found in cell membranes in the skin of your scalp, and in the natural oils that keep your scalp and hair hydrated. Other options: essential fatty acids from fish like herring, sardines, trout, and mackerel, as well as avocado, pumpkin seeds, and walnuts (see below for more wonderful things about walnuts.)
These are the only type of nut that have a significant amount of omega-3 fatty acids. They're also rich in biotin and vitamin E, which helps protect your cells from DNA damage. Since your hair rarely gets much shielding from the sun, this is especially great, Drayer says. Too little biotin can lead to hair loss. Walnuts also have copper, a mineral that helps keep your natural hair color rich and lustrous, Fishman says. Other options: Try using walnut oil in your salad dressing or stir-fry instead of canola or safflower, Fishman says.
Oysters are rich in zinc, a lack of which can lead to hair loss (even in your eyelashes), as well as a dry, flaky scalp. Three ounces has a whopping 493% of your daily value. You can get some zinc through fortified cereals and whole grain breads, but oysters can boast a good level of protein too. "Remember, hair is about 97% protein," Drayer says. Without enough protein, your body can't replace the hairs that you naturally shed every day and what you do make can be dry, brittle, or weak. Other options: Get your fill of zinc with nuts, beef, and eggs.
Sweet potatoes are a great source of the antioxidant beta carotene, which your body turns into vitamin A. "Basically, every cell of the body cannot function without enough A," Fishman says. It also helps protect and produce the oils that sustain your scalp, and being low on vitamin A can even leave you with itchy, irksome dandruff. Other options: Carrots, cantaloupe, mangoes, pumpkin, and apricots are all good sources of beta carotene.
A great source of protein, eggs are loaded with four key minerals: zinc, selenium, sulfur, and iron. Iron is especially important, because it helps cells carry oxygen to the hair follicles, and too little iron (anemia) is a major cause of hair loss, particularly in women, Drayer says. Other options: You can also boost your iron stores with animal sources, including chicken, fish, pork, and beef.
The iron, beta carotene, folate, and vitamin C in spinach help keep hair follicles healthy and scalp oils circulating. Other options: Try similarly nutrient-rich dark, leafy vegetables such as broccoli, kale, and Swiss chard.
Tiny but mighty, these legumes are teeming with protein, iron, zinc, and biotin, says Fishman, making it a great staple for vegetarian, vegans, and meat eaters. Other options: Toss other beans such as soybeans (the young ones are called edamame) and kidney beans into your soup or salad.
Cruise the dairy aisle for low-fat options such as Greek yogurt, which is high in hair-friendly protein, vitamin B5 (pantothenic acid -- an ingredient you'll often see on hair care product labels), and vitamin D. Emerging research links vitamin D and hair follicle health, but exactly how that works isn't clear, Fishman says. Other options: Cottage cheese, low-fat cheese, and skim milk also fit the bill.
Exotic super fruits may come and go but when it comes to vitamin C, "It's hard to top this nutrient superhero," Drayer says. C is critical for circulation to the scalp and supports the tiny blood vessels that feed the follicles. Too little C in your diet can lead to hair breakage. Other options: Kiwis, sweet potatoes, tomatoes, and strawberries.
This everyday entree is extraordinary when it comes to protein, as well as hair-healthy zinc, iron, and B vitamins to keep strands strong and plentiful. Because hair is nearly all protein, "foods rich in protein are literally giving you the building blocks for hair," Drayer says. Other options: Lean cuts of beef are another good source of lean protein.

If you've got curly hair, you may daydream about having smooth, straight locks. There are several options for taming curls, and each has pros and cons.
Keratin Treatments Many women swear by this salon treatment, which smoothes and straightens hair by coating it with chemicals. Stylists say it provides a glossy, frizz-free finish and makes hair much easier to care for. To keep that finish, you need to reapply keratin treatments about every 12 weeks. Treatments can cost $200 or more. Keratin treatments don't work well on tightly kinked hair. And they can make your hair brittle, so you'll need to use conditioner generously when you shampoo. Or you may want to skip keratin treatments altogether. There have been safety questions about the treatments, particularly for stylists who work with them. Some brands may contain or release unsafe levels of formaldehyde, a chemical that has been linked to health problems, including cancer.
Chemical Relaxers Salon and home chemical relaxers last longer than keratin. The treated hair stays straight permanently. If you have it done in a salon it's about half the price of a keratin treatment. But the roots grow back curly. That two-textured look bothers some women, says Anthony Cress, a hair stylist in Newport Beach, CA. Salon stylists usually use relaxers with lye because they work faster. They can be more irritating to your scalp than those without lye and are best done in salons, says Paradi Mirmirani, MD, a dermatologist with Kaiser Permanente in Vallejo, CA.
If you straighten your hair at home, use a no-lye relaxer, which is less likely to irritate your scalp, and don't leave it on longer than directed. All chemical relaxers can make your hair dry and brittle and harm your scalp. And the damage can build up. For touch-ups, though, you only need to apply the relaxer to your roots, not all over. Victoria Barbosa, MD, MPH, a dermatologist in Chicago, says she advises her patients not to use a chemical relaxer if their scalp is unhealthy or they have serious problems with hair breakage or hair loss. To protect your hair, don't use a relaxer more than every 8 weeks, and use moisturizers generously on your hair. Blow-Dryers and Flat Irons If you don't want to pay for salon treatments or expose yourself to chemicals, you can straighten your hair between shampoos or swims with a blow-dryer or flat iron. “Heat rearranges hydrogen bonds in the hair, causing temporary straightening, which lasts until the hair is exposed to humidity or water,” Barbosa says.
Too much heat can also damage hair. To prevent damage, try these tips: Blow-dry only once or twice a week on a low setting. “If you start getting flyaways, breakage, or the hair isn't as shiny, what you're doing is too much,” Mirmirani says. To cut back on heat, wash your hair at night. Let it air-dry, and straighten it with a flat iron in the morning. Use a flat iron on dry hair only. Keep it on a low setting and don't hold it in one place too long. "If the flat iron or curling iron is not moved along the hair shaft swiftly enough, an entire section of hair can be singed off at one time," Barbosa says. Cress suggests stretching the time between stylings by using dry shampoo. "It absorbs the oils from your scalp, and you don't have to restyle," he says. Going Natural The simplest option is also best for your hair: Embrace your curls. "I don't like to say, 'Go straight for the chemicals,'" Cress says. "It can be an uphill battle to keep your hair moisturized if you blow-dry and color and have other products and treatments in your routine." Ask your stylist how to style your hair so its natural curliness is more appealing to you. The trick is to treat your hair gently. Don't towel dry it vigorously like you're polishing a bowling ball. "It is instantly setting yourself up for failure and frizz,” Cress says. “Instead, use a wide-tooth comb to style it the way you want to wear it, then let your hair fall into your hand with a towel and gently squeeze the towel." Finish shaping it with a product like light liquid gel or mousse.
