The foods people eat regularly affect the hair growth cycle and the overall quality of their hair. Specific proteins, vitamins, fats, and minerals are crucial for healthy hair. Nutritionists and dermatologists confirm that certain nutritional deficiencies lead to dry, dull, and straggly hair. In some cases, improper diet can lead to hair loss and thinning. A varied, nutritious diet can help reverse these symptoms once the deficiency is restored. A balanced nutritional regimen also significantly affects nail and skin health.
How does the hair cycle work?
Our hair continually goes through cycles: growth, rest, and shedding. You have about 100,000 individual hairs on your head at any moment, and on average, each hair grows for nearly 1,000 days before entering a resting period before they are shed.
There are four main stages in the cycle of hair growth:
- Anagen phase (growing stage)
- Catagen phase (transitional stage)
- Telogen phase (resting stage)
- Exogen phase (shedding stage)
During this cycle, the hair grows at approximately one-half-inch per month, though several external factors can influence this.
We cannot control factors like age, sex, and genetics. But nutrition is one controllable element that can make a huge difference in hair health.
What is the anatomy of hair?
Let's examine your hair's basic anatomy to better understand what nutrients are needed for optimal hair growth. Hair primarily comprises a complex protein called keratin, which is also found in your fingernails and skin.
Each hair strand comprises the hair follicle and the hair shaft. The follicle is the portion of hair beneath the skin where new growth happens.
This follicle base is called the bulb and comprises stem cells that produce the shaft. The bulb is nourished by blood vessels in the scalp that supply oxygen and nutrient-rich blood to support hair growth and health. Since your hair is primarily composed of protein, it makes sense that protein, vitamins, and minerals are essential for strong hair.
Foods for healthier, thicker hair
Since diet plays such a massive part in keeping hair luscious and strong, it's essential to prioritize your food choices and nutritional lifestyle. Eating a diet rich in vitamins and minerals that support healthy hair is crucial to achieving thicker tresses. Here are some foods you can start incorporating into your daily meals.
Eggs
The most common nutritional deficiencies associated with hair thinning and loss include low iron, vitamin D, and biotin levels. Eggs are an excellent, natural source of these nutrients, especially B vitamins. They also have two carotenoids, lutein and zeaxanthin, which play a significant role in cellular health, particularly skin, hair, and eyes.
Scrambled eggs, hard-boiled eggs, or egg sandwiches are great ways to incorporate them into your daily rotation. You can even add hard-boiled eggs to your lunch salad or on top of a turkey burger.
Salmon
Fish like salmon, mackerel, and tuna are rich in omega-3 fatty acids and protein sources. These fan-favorite fish can help keep your hair strands strong and reduce potential hair loss, inducing inflammation around the scalp.
Salmon is more than just a delectable treat; it's a powerhouse of essential nutrients that can do wonders for your hair. Rich in omega-3 fatty acids, incorporating this fish into your diet can potentially increase hair density and reduce the shedding phase known as telogen. Moreover, these fatty acids help nourish the hair follicles, promoting shinier and healthier locks. If salmon isn't to your taste, other fish like mackerel, tuna, and herring are equally beneficial. For an exciting twist, try sardine toast made by mashing sardines with olive oil, lemon juice, salt, and red pepper flakes and spreading it over whole-grain toast.
Nuts
Nuts, often considered nature's snack, have many health benefits. Specifically, for hair, skin, and nails, they provide essential nutrients due to their healthy fats. Almonds, cashews, and walnuts are packed with vitamins and zinc. Not getting enough of these nutrients can result in hair thinning. Among the assortment, pistachios stand out as they are rich in biotin, a vitamin essential for robust hair, and antioxidants that protect against oxidative stress. They can be added to pesto or used as a crunchy coating for fish fillets.
Chock-full of biotin, one serving of almonds daily can help stimulate new follicle growth and help thicken hair. Almonds are also a good source of healthy fats, vitamin E, and magnesium. You can enjoy almonds alone, on top of yogurt, or mixed with dried fruit.
Legumes
The connection between protein and hair health is significant. Our hair shaft mainly comprises a protein called keratin. Hence, having a protein-rich diet is pivotal. Legumes like beans, chickpeas, peanuts, soybeans, and lentils are excellent protein sources and also contain other hair-nourishing nutrients such as zinc, iron, biotin, and folate. These nutrients not only promote hair growth but also protect against premature greying. While these are plant-based sources, animal-based proteins, like chicken breast, can also be included for similar benefits.
Spinach
Dark leafy greens, especially spinach, are a treasure trove of nutrients. Vitamin A, abundant in spinach, is crucial for hair growth. However, it's essential to note that excessive intake can be counterproductive and lead to hair loss. Hence, getting vitamin A from food rather than supplements is safer. Moreover, spinach also provides iron, which plays a role in combating female pattern hair loss. Studies have indicated that those with hair loss issues often have deficient iron levels.
Avocados
These creamy fruits are not just for your toast; they're packed with hair-loving nutrients. One of the standout elements in avocados is Vitamin E. This antioxidant ensures your hair gets all the nourishment it needs. Consuming an avocado can fulfill a significant portion of your daily vitamin E requirement. Research has shown a positive impact of vitamin E on individuals experiencing hair loss, which could be attributed to its antioxidative properties.
Seeds
Seeds are tiny but mighty. Flaxseeds, chia, sunflower, and pumpkin seeds contain nutrients vital for hair health, such as vitamin E, zinc, and selenium. Additionally, flaxseeds and chia seeds offer much-needed omega-3 fatty acids. Some studies suggest that pumpkin seed oil can promote hair growth when applied topically, though more research is needed.
Yogurt
Yogurt is a multifaceted ingredient, offering both taste and nutrition. Rich in protein, probiotics, and various other nutrients, it's no wonder it's used in numerous DIY hair masks. Consuming yogurt has shown noticeable improvements in hair texture and sheen. Additionally, yogurt contains vitamin B5, which can stimulate hair follicle growth, ensuring thick and vibrant hair.
Peppers
Both sweet and spicy peppers have unique benefits. Rich in vitamin C, they aid in iron absorption, which is crucial for those battling hair loss due to iron deficiency. Peppers' antioxidant properties also play a role in reducing oxidative stress, a known cause of hair loss. Additionally, they offer a good amount of vitamin A. For those who prefer some heat, chili peppers contain capsaicin, which has shown promise in promoting hair growth.
Cruciferous Vegetables
These vegetables, including broccoli and Brussels sprouts, are loaded with hair-boosting nutrients. From vitamins A and C to folic acid and biotin, they offer a holistic nutrient profile that promotes healthy hair growth and prevents premature greying.
Collagen
Collagen, particularly fish-derived collagen peptides, is increasingly recognized for its benefits in hair health. MDhair Marine Collagen, rich in Hydrolyzed Marine Collagen, provides types I and III collagen, essential for new collagen production in the body. This directly aids in strengthening and promoting hair growth, which is crucial for those experiencing hair loss. The supplement also includes Hyaluronic Acid, enhancing hair hydration and elasticity, key factors in maintaining hair strength and preventing breakage. Vitamin C in the formula also supports new collagen synthesis, vital for hair, skin, and nail health. This combination of ingredients in a sugar-free, sulfate-free, and non-GMO supplement makes MDhair Marine Collagen a beneficial choice for improving hair, skin, and nail health while being convenient to incorporate into daily routines due to its easy solubility in beverages.
Dark berries
Berries like strawberries, blueberries, and blackberries provide a healthy dose of antioxidants to protect the hair follicles. Vitamin C helps support collagen production and scalp circulation. Berries also aid in absorbing iron, an essential mineral in the body. Eating berries regularly can make healthier hair less prone to breakage and split ends.
Sweet potatoes
Sweet potatoes can help restore shine and moisture to your locks. They are loaded with beta carotene, an antioxidant converted to vitamin A by the body when consumed. Vitamin A has been shown to protect against dull, dry hair and encourage the scalp's glands to produce sebum (oil) to keep the hair moisturized.
Baked sweet potatoes can be a delicious dinner side, topped with butter and a bit of brown sugar. You can also cut them and bake them to make sweet potato fries!
Kelp
Kelp promotes hair growth due to its high iodine levels, which are thought to aid in healthy thyroid function and can contribute to hair thinning. Thanks to its rich vitamin and mineral content, sea kelp can also strengthen hair and prevent damage. Iron, folate, magnesium, zinc, and l-lysine in kelp effectively boost hair fullness and health. Kelp is an excellent addition to your stew or favorite noodle dish. It can also be dried out and enjoyed as a crunchy snack.
