A healthy diet can help your hair grow longer and stronger. Eating a variety of nutritious foods can boost hair health, and even stimulate growth. Nutrient deficiencies can cause hair loss, and restoring these nutrients may encourage hair to grow again. A balanced diet, rich in vitamins and minerals, is essential for hair growth. For example, vitamin C helps produce collagen, a protein that strengthens hair. Selenium is also important, as it is involved in creating hair, and a vitamin A deficiency can cause poor hair growth. A Mediterranean diet, rich in vegetables, whole grains, lean meats and healthy fats, is recommended for healthy hair.

What You'll Learn
Include vitamins and minerals like zinc, selenium, and biotin
A healthy and balanced diet is essential for hair growth, and certain vitamins and minerals can play a crucial role in this process. Here's how you can include vitamins and minerals like zinc, selenium, and biotin in your diet to support hair growth:
Zinc
Zinc is an essential mineral that has been scientifically proven to support hair growth and prevent hair loss. Maintaining optimal zinc levels is crucial for healthy hair. While supplements are an option, most people can obtain sufficient zinc through their diet. Foods rich in zinc include meat, seafood (especially oysters), legumes, nuts, seeds, dairy products, and whole grains. The recommended daily intake of zinc is 8-11 mg for adults. However, it is important to note that both zinc deficiency and excess can impact hair health. Low zinc levels may manifest as hair thinning and slow growth, while too much zinc can interfere with the absorption of other vital minerals like iron, leading to similar hair problems. Therefore, it is essential to strive for balanced zinc levels through a varied and nutritious diet.
Selenium
Selenium is another important mineral that may influence hair health. Some studies suggest that insufficient selenium intake can lead to slower hair growth or hair shedding. However, these studies have primarily been conducted on animals, and there is limited evidence of the same effects in humans. Selenium deficiency is relatively rare, and there is insufficient research linking it directly to hair loss in humans. Nonetheless, maintaining adequate selenium levels may help stimulate hair growth, protect hair from UV radiation, and promote scalp health by reducing dandruff and seborrheic dermatitis. The recommended daily intake of selenium is 55 micrograms, and it can be found in foods like Brazil nuts, tuna, ham, beef, and chicken.
Biotin
Also known as vitamin B7 or vitamin H, biotin is a water-soluble vitamin that has gained popularity for its claimed benefits on hair growth. It is essential for the production of a hair protein called keratin. While biotin deficiencies are uncommon in those consuming a balanced diet, supplements are often marketed for hair growth. Clinical improvements have been observed in patients with underlying pathologies for poor hair growth who received biotin supplementation. However, research demonstrating the efficacy of biotin in healthy individuals is limited. Eggs are an excellent natural source of biotin and protein, both of which are essential for hair growth. The recommended daily intake of biotin for adults is 30 μg, which can typically be achieved through a well-rounded diet.
In conclusion, while a varied and nutritious diet is the best approach to obtaining these vitamins and minerals, supplements can be considered in cases of deficiency or when recommended by a healthcare professional. It is always advisable to consult a doctor or nutritionist before starting any supplementation to ensure it aligns with your individual needs and health goals.

Eat more protein-rich foods
A well-rounded diet that includes a variety of protein-rich foods is essential for supporting hair growth and maintaining healthy hair. Hair follicles are made mostly of protein, and a lack of protein can lead to hair loss and dull, weak hair.
Protein-rich foods contain certain amino acids, such as L-lysine, which is responsible for the shape and volume of the hair. L-lysine is also present in the hair's root, and getting enough of this amino acid can prevent hair loss and promote regular hair growth.
Oysters are an excellent source of protein and provide one of the highest amounts of zinc, a crucial mineral for hair growth. A lack of zinc has been associated with telogen effluvium, a type of hair loss. Eggs are another protein-rich food that provides essential nutrients for hair health, including biotin, a mineral that may help boost hair growth. Other protein-rich foods that support hair growth include salmon, Greek yoghurt, lentils, and lean meats.
In addition to protein-rich foods, a balanced diet that includes a variety of other nutrients is also important for hair growth. This includes vitamins A, C, D, and B-vitamins, as well as healthy fats, zinc, selenium, and iron. These nutrients can be found in a variety of whole grains, fruits, and vegetables, such as leafy greens, sweet potatoes, berries, avocados, and nuts.

Consume omega-3 fatty acids
Consuming omega-3 fatty acids is essential for hair growth, as they provide nutrients to hair follicles and skin, promoting circulation in the scalp and preventing hair follicle inflammation. While there is limited evidence of the benefits of omega-3s for hair health, they are essential for the body to function correctly.
Omega-3 fatty acids can be obtained through diet and supplements. Fatty fish, such as mackerel, are excellent sources of omega-3s and provide additional nutrients like protein, selenium, vitamin D3, and B vitamins, which contribute to healthy hair. A 2018 study found that mackerel-derived fermented fish oil applied topically to mice significantly stimulated hair growth.
Fish oil supplements are generally considered safe and may be beneficial for hair health and thinning hair symptoms. However, it is always recommended to consult a healthcare provider before introducing supplements to your routine.
For those who do not consume fish, flaxseeds provide a type of omega-3 fatty acid that is not as readily used by the body but can still be a valuable addition to the diet. Consuming a variety of seeds ensures a diverse range of nutrients.
While the direct impact of omega-3 fatty acids on hair growth requires further research, their overall health benefits and limited side effects make them a worthwhile addition to a diet focused on supporting hair health.

Get enough vitamin C
Vitamin C is an essential nutrient for hair health and growth. It is a powerful antioxidant that helps protect hair follicles from damage caused by free radicals. Free radicals are naturally formed when the body turns food into glucose for energy production, and they can make hair weak, brittle, and thin, interrupting hair growth. Vitamin C's antioxidant properties reduce the formation of free radicals and minimise their harmful effects.
Vitamin C is also crucial for creating and maintaining collagen, the protein that acts as the "glue that holds the body together". Collagen strengthens hair strands, preventing them from becoming brittle and breaking off. Additionally, vitamin C aids in iron absorption, helping to prevent iron deficiency anaemia, which has been linked to hair loss.
A vitamin C deficiency can lead to dry hair, split ends, and hair loss. To ensure adequate vitamin C intake, aim to include a variety of vitamin C-rich foods in your diet. Excellent sources of vitamin C include citrus fruits like oranges, lemons, and limes; berries, especially strawberries; peppers; broccoli; leafy greens like spinach; and other fruits and vegetables like kiwi, papaya, mango, and pineapple.
While supplements are an option, registered dietitian Michelle Dodd recommends focusing on obtaining nutrients from whole foods whenever possible, as the body absorbs nutrients better from food sources. Additionally, be sure to stay hydrated, as dehydration can slow hair growth by drying out the scalp. Aim for at least 64 ounces (2 litres) of water per day, adjusting upwards if you live in a hot climate or engage in activities that make you sweat.

Drink more water
Drinking water is essential for hair health. Dehydration dries out the scalp, slowing hair growth and causing hair loss. Ensuring you are properly hydrated supports the hair's natural growth cycle.
The recommended amount of water to drink per day is 64 ounces (2 litres). However, this may vary depending on factors such as your body weight, level of physical activity, and environmental conditions. For instance, if you are exercising, you should aim to drink an additional 12 ounces of water for every 30 minutes of exercise. Similarly, if you live in a hot climate or sweat a lot, you will need to increase your water intake.
Drinking water is especially important if you consume caffeinated beverages, as coffee, sodas, and other caffeinated drinks can contribute to dehydration. It is recommended to drink a glass of water for every caffeinated drink you have.
While it may take a few months to see noticeable changes in your hair growth patterns after correcting dehydration, proper hydration is a crucial step towards achieving healthy hair growth.
In addition to drinking water, it is important to eat a balanced diet rich in nutrients that support hair growth, such as vitamins A, B, C, D, and E, as well as minerals like iron, zinc, and selenium.
