Home Lab Notes Hair Aggressors 8 Diet Tips for Great Hair

Turns out the old adage is true: You are what you eat. Or at least your hair may be. So how does diet actually affect your hair?

When it comes to scoring healthy (strong, shiny, bouncy) hair, using custom, high-quality hair care products is an important part of the equation. But so is eating a well-balanced diet. Diet affects your texture, hair growth and hair health. Your hair (and skin and nails) are among the last parts of our bodies to receive nutrients. In line ahead of hair? Life-sustaining organs like your brain, liver and lungs. So, if and when your diet is lacking, your inner organs will hungrily take their share of protein, vitamins and other nutrients, leaving little for your hair. This affects hair growth by causing strands to become dry, brittle, dull and slow-to-grow.

To ensure your last-in-line hair gets what it needs, start by eating a well-balanced diet (protein, lots of veggies and fruit, whole grains). Because we metabolize food differently, loading up on specific foods that are known to be extra-nourishing to the hair will help improve the diet-and-healthy-hair-success ratio. The following foods and nutrients have been shown to be especially beneficial to the hair and scalp.

Boost shine and strength with seafood

Omega-3 fatty acids help nourish the scalp’s hair follicles, enabling them to grow strands that are strong and resistant to damage. This nutrient also helps hydrate dry and brittle hair, making it shinier, more elastic and less apt to break and split. However, our bodies can’t make our own omega-3 fatty acids, so, it’s up to us to load up on it when we eat. The best sources of omega-3 come from the sea: salmon, lake trout, albacore tuna and sardines are all particularly high in this nutrient. If seafood isn’t an option for you, try walnuts, chia seeds, winter squash, or omega-3 enriched eggs instead.

Encourage growth by going green

Dark green leafy vegetables, such as spinach, kale, swiss chard, and beet greens are all packed with iron, a notoriously hard-to-come-by nutrient that is essential for healthy hair growth. A lack of iron (especially when it reaches anemic levels) can trigger hair loss, while being flush in iron stimulates hair follicles and encourages productive growth. Other good sources of iron include: lean beef, oysters, lentils, quinoa, and fortified cereals. Bonus: Most dark green leafy veggies are also high in folic acid, a B vitamin that encourages the production of red blood cells, the vehicles that take oxygen to the scalp, keeping it (and thus future hair growth) in tip-top shape.

Bulk up with protein

Hair is made up of a type of protein called keratin that makes strands strong and resistant to breakage. However, each hair is created with a finite amount of protein and, therefore, the reserves must be regularly replenished to maintain a strand’s strong structure. Lean meats, such as skinless chicken and turkey, pork, or lean ground beef are especially good sources of protein. You can also find protein in plant-based sources, such as legumes, dairy, tofu, nuts, nut butters, and eggs. One caveat: Protein is excellent for building strength, but you can eat too much of a good thing. There is some evidence that eating a very high-protein diet, especially when most of the sources of protein are meat (and all that meat is limiting your intake of other necessary nutrients), can have an adverse effect on hair, taking it from strong to brittle. Thus, be sure to vary your sources of protein, mixing both meat and plant-based options — and balance it by eating plenty of veggies.

Prevent breakage with vitamin C

Frequently heralded for its anti-virus and antioxidant properties, vitamin C is also excellent at increasing hair’s elasticity, making it less prone to snapping and tearing. You’re most-likely aware that citrus fruits like oranges and grapefruits are high in vitamin C, but you can also find it abundantly in strawberries, kiwi, guava, broccoli, brussel sprouts and bell peppers.

Speed up hair repair with spices

Sprinkling your foods with certain zesty spices, such as cinnamon, cayenne pepper, and ginger, has been shown to boost blood flow and accelerate the rate at which the circulatory system delivers nutrients to your scalp. The result: an increase in nutrients for existing hair and healthier growth for future strands.

Temper hair loss by loading up on zinc

A deficiency in this mineral has been shown to cause hair loss—even in brows and eyelashes. Why? Zinc is directly responsible for maintaining the cells that produce new hair so, when you’re lacking in this nutrient, those cells don’t work as hard…or may stop working altogether. You can find zinc in grass-fed beef, chicken, oysters, chickpeas, kefir or yogurt, and mushrooms. It’s also frequently found in fortified cereals.

Boost hydration with bright colors

Vivid, orange fruits and veggies, such as sweet potatoes, mango, pumpkin, and squash, are full of beta carotene, which promotes a healthy level of the scalp’s sebum production, keeping hair moisturized and lustrous.

Maintain nutrition by scaling back on sugar

While we’re on the topic of hair health and diet, it’s also worth mentioning that when it comes to how diet affects your hair, what you don’t eat can improve hair health too. Specifically, refined sugar, the kind found in white bread, pasta and candy, can cause an overproduction of androgen, a hormone notorious for shrinking hair follicles and triggering hair loss. Alcohol (beer, wine, spirits) can also have negative implications for the hair, as it inhibits the way we process zinc—and we now know zinc is good for the hair. Alcohol is also dehydrating and can cause hair to become dull and lank.
