What You'll Learn
Include protein-rich foods like chicken, turkey, fish, dairy, legumes and nuts
A healthy diet can help your hair stay strong and shiny. Eating a balanced diet rich in vitamins and minerals may help promote hair growth, especially if your hair loss is due to poor nutrition.
Protein is critical for keeping your hair healthy, and hair follicles are mostly made of protein. A lack of protein may cause hair loss. The protein in meat aids growth and helps repair and strengthen hair follicles. Red meat, in particular, is rich in a type of iron that is easy to absorb. This mineral helps red blood cells deliver oxygen to all cells in the body, including hair follicles. However, overconsumption of red meat, especially processed red meat, has been linked to an increased risk of cardiovascular disease, colorectal cancer, and type 2 diabetes.
Chicken and turkey are good sources of protein and contain iron with high bioavailability, meaning the iron is readily available to the body. Chicken and turkey also contain zinc, which is important for scalp health. A lack of zinc can lead to hair loss and a dry, flaky scalp.
Fish is another great source of protein. Fatty fish like salmon, herring, and mackerel have nutrients that may promote hair growth. They are excellent sources of omega-3 fatty acids, which may support hair growth. An older study of 120 females found that a supplement containing omega-3 and omega-6 fatty acids and antioxidants reduced hair loss and increased hair density.
Dairy products are also a good source of protein and contain vitamin B12, which is important for hair health. In addition, dairy provides calcium, which is important for bone health.
Legumes, such as kidney beans and lentils, are plant-based sources of protein. They also contain iron, biotin, and zinc, which are all important for hair health.
Nuts are also a good source of protein and are rich in zinc and selenium. These minerals support scalp health, and a healthy scalp is important for hair growth.

Consume vitamins A, B6, B12, C, D and E
Consuming a variety of vitamins is important for preventing and managing hair loss. Vitamins A, B6, B12, C, D, and E all play a role in maintaining healthy hair.
Vitamin A is important for hair growth and sebum production, which helps keep hair healthy. Sweet potatoes are an excellent source of beta-carotene, which the body converts into vitamin A. A medium-sized sweet potato provides up to 160% of your daily vitamin A needs. Spinach is another great source of vitamin A, providing up to 20% of your daily needs in just one cup. However, it is important to note that supplementing with too much vitamin A can lead to hair loss.
Vitamin B6 and B12 are also important for hair health. B vitamins are water-soluble, so it is important to consume them daily. Vitamin B6 can be found in bananas, potatoes, and spinach, while vitamin B12 is abundant in meat, poultry, fish, and dairy products.
Vitamin C helps the body produce collagen, a protein that strengthens hair and prevents it from becoming brittle and breaking. It also aids in iron absorption, which is essential for hair growth. Citrus fruits and tomatoes are excellent sources of vitamin C.
Vitamin D has been linked to hair health, and supplementing with low levels of this vitamin can improve symptoms of androgenetic alopecia and telogen effluvium, two common types of hair loss. Fatty fish are a good source of vitamin D.
Vitamin E may support hair growth and can be found in avocados. One medium avocado provides 28% of your daily vitamin E needs.
In addition to consuming these vitamins, it is important to eat a balanced diet rich in nutrients that support hair growth, such as protein, essential fatty acids, and zinc.

Eat iron, magnesium, zinc and selenium
Iron, magnesium, zinc, and selenium are essential trace minerals that can contribute to healthy hair. Here is how you can incorporate them into your diet:
Iron
Iron is essential for the proper functioning of our bodies. It helps transport oxygen to our cells and tissues, including the hair follicles. When iron levels are low, hair follicles may not receive enough oxygen, leading to weakened hair shafts and hair loss. You can increase your iron levels naturally through your diet. Certain foods, like coriander leaves, amla (Indian gooseberry) juice, and pomegranate, are rich in iron and can help boost its absorption.
Magnesium
Magnesium is often referred to as the "anti-stress" mineral, and it plays a role in over 300 biochemical reactions in the body. A magnesium deficiency can lead to hair thinning, hair loss, and scalp inflammation. Spinach, almonds, avocados, black beans, and pumpkin seeds are all excellent sources of magnesium. Incorporating these foods into your diet can support hair follicles, improve circulation to the scalp, and stimulate growth.
Zinc
Zinc is crucial for hair follicle development and maintenance. It supports the production and function of various cells within the hair follicles, including those responsible for synthesising keratin, the protein that forms the structural foundation of hair strands. A zinc deficiency can disrupt the balance of nutrients required for optimal hair growth, leading to hair loss, thinning hair, and increased hair shedding. Excellent sources of zinc include pumpkin seeds, meat, and poultry.
Selenium
Selenium is a trace mineral that plays a role in fertility, immune health, DNA synthesis, thyroid hormone metabolism, and other important functions. It is also an antioxidant that helps fight oxidative stress. However, too much selenium can potentially lead to hair loss. The daily recommended intake of selenium for adult men is around 55 micrograms, and it can be obtained from food sources like meat, cereals, grains, eggs, poultry, fish, and dairy. Brazil nuts are very high in selenium, so consuming them daily may lead to excessive selenium levels.

Focus on omega-3 fatty acids
Omega-3 fatty acids are essential for the health of your skin, hair, and nails. While more research is needed to establish a direct link between omega-3 and hair health, it is known that omega-3 has many health benefits and few side effects. Therefore, it is unlikely to be harmful.
Some studies suggest that omega-3 may improve hair growth and thickness. In a 2015 study, half of the 120 participants took an omega-3 and omega-6 supplement for six months, while the other half did not. The group taking the supplement had more hair in the active growth phase than the control group. Additionally, in a study on rat whisker follicles, researchers found that treating follicles with fermented mackerel oil, which contains omega-3 fatty acids, resulted in longer hair fibres than untreated follicles.
To incorporate omega-3 into your diet, eat fatty fish such as salmon, mackerel, sardines, anchovies, and tuna. The American Heart Association recommends eating one to two servings of seafood per week, preferably from oily fish. If you don't eat fish, you can still get omega-3 through plant sources, although the Omega-3 Index, which measures the percentage of omega-3 EPA and DHA in your blood, does not test for omega-3s from ALA.
It is important to note that while dietary supplements containing omega-3 are available, it is always best to consult a doctor before taking any new supplement, especially if you have a fish or seafood allergy or take medications that affect blood clotting.

Avoid trans-fat, empty carbs and very low-calorie diets
A healthy diet is essential for maintaining strong and shiny hair. Eating a balanced diet rich in essential fatty acids, vitamins, and minerals can help prevent hair loss and promote hair growth. However, certain dietary choices can negatively impact hair health and lead to hair fall. One such choice is consuming trans fats, empty carbs, and following very low-calorie diets.
Trans fats are unsaturated fats that have been chemically altered to make them more solid at room temperature. They are commonly found in fried foods, processed snacks, and baked goods. While trans fats can provide a convenient source of energy, their excessive consumption can lead to various health issues, including an increased risk of heart disease and inflammation. Additionally, trans fats can contribute to hair fall by affecting the body's ability to absorb essential nutrients required for hair growth.
Empty carbs, also known as simple carbohydrates, refer to sugars and refined grains that have been stripped of their fibre, vitamins, and minerals during processing. These include white bread, pastries, sugary drinks, and candy. While empty carbs can provide a quick energy boost, they offer little nutritional value and can lead to spikes in blood sugar levels. Consuming excessive empty carbs can increase the risk of type 2 diabetes and insulin resistance, both of which have been linked to hair loss.
Very low-calorie diets, often undertaken for rapid weight loss, can also contribute to hair fall. Restricting calorie intake can affect the energy supply to the hair follicle, leading to hair thinning and hair loss. Additionally, these diets may not provide sufficient protein, which is essential for hair growth. Amino acids, the building blocks of protein, are crucial for proper hair growth and strength. Therefore, a diet lacking in calories and protein can negatively impact hair health and lead to hair fall.
To maintain healthy hair and prevent hair fall, it is crucial to avoid excessive consumption of trans fats and empty carbs. Instead, opt for a balanced diet rich in whole foods, including lean proteins, healthy fats, complex carbohydrates, and a variety of fruits and vegetables. Additionally, ensuring adequate calorie intake and including protein-rich foods in your diet can help support hair health and reduce the risk of hair fall. Consulting with a healthcare professional or a registered dietitian can provide personalized guidance on how to make these dietary adjustments sustainably and effectively.
