Essential Nutrients for Healthy Hair

It’s vital to ensure that your diet is rich in essential nutrients in order to maintain healthy hair and prevent hair loss. Essential nutrients like proteins, vitamins, minerals, and fats play key roles in strengthening hair, preventing breakage, and promoting growth.

essential nutrients for healthy hair


Proteins are the building blocks of hair and constitute about 95% of the hair structure. Your diet can significantly impact hair growth and its strength if you include protein-rich foods like eggs, lean meats, fish, dairy products, legumes, nuts, and seeds in your diet.

However, if you live in the US, you are unlikely to have protein deficiency. Do you know that an average American, including vegans, consumes more than twice the recommended daily amount of protein? In fact, you might be overeating protein right now. This can instead lead to biotin deficiency, which can also cause hair loss. So, if you notice that your hair is brittle and starting to shed more than before, then you should consult a doctor about your protein intake.


Vitamins are essential for maintaining the healthy growth of hair. Vitamin A helps in the production of sebum. It is an oily substance which keeps the scalp moisturized. Vitamin B supports overall hair health, and biotin helps prevent hair loss. Whereas vitamin C is crucial for collagen production that helps strengthen hair, vitamin D helps in hair follicle health, and vitamin E helps reduce oxidative stress on the scalp, as it is known for its antioxidant properties.


Minerals like zinc, iron, selenium, and copper are essential for strengthening hair and preventing loss. Iron helps transport oxygen to hair follicles, whereas zinc aids in tissue repair and growth. Selenium plays a role in supporting the scalp and hair, and copper assists in maintaining hair pigmentation.

Zinc and selenium are essential trace minerals that your body can’t produce on its own. So you must consume them through eating. Many studies have shown that selenium deficiencies can affect the health of the scalp and hair follicles, whereas too little zinc can cause acute and chronic hair loss.

Consume heart-healthy nuts and good zinc and selenium sources to keep your hair as healthy as possible. Also, consider goods that are rich in iron. Lentils, other legumes, and dark leafy greens, like spinach, broccoli, and kale, are rich in iron.

Omega-3 Fatty Acids

These are found abundantly in fatty fishes like salmon and trout, walnuts, flaxseeds, and chia seeds. It helps in promoting healthy scalp and hair growth. These fatty acids also help in reducing inflammation and keep the scalp hydrated.


Dehydration can lead to brittle and weak hair. So, drinking plenty of water throughout the day keeps your scalp hydrated, promoting healthy hair growth and preventing dryness and breakage.

Balance Diet

Adopt a balanced diet that includes a variety of food groups. It will ensure that you obtain a wide array of nutrients necessary for healthy hair. Also, have a mix of proteins, healthy fats, fruits, vegetables, and whole grains in your daily meals.
