5 Essential Vitamins For Hair Growth To Include In Your Diet

Most of us find it difficult to grow thick, long hair. Trying hair care treatments means regularly shelling big bucks, which is not a feasible option for many. But, there is a remedy – using vitamins for hair growth. That’s right! Instead of heading to salons for regular hair maintenance and care treatments, eating the right vitamins can improve your hair health. Don’t believe us? Keep reading to know more.

While it is necessary to visit your hairdresser, take care of your hair, and be patient, we often overlook the importance of nutrition.

When people say that healthy hair is a trait of good health, they are correct. Both good health and healthy hair result from a well-balanced diet that includes the proper proportions of fats, carbohydrates, vitamins, proteins, minerals, water, and fiber.

Proteins, minerals, and vitamins are the three most critical nutrients for hair. Their consumption in the correct amounts results in rapid and healthy hair growth. An appropriate diet is 90% of what you need for desired hair density and texture.

Take a look at the list of vitamins and minerals listed below to see how they help you grow healthy hair. Keep reading to know more!

5 Essential Vitamins For Hair Growth

1. Vitamin A

Vitamin A is one of the four fat-soluble vitamins. Studies show that it plays an important role in the development of epithelial tissues, including skin, hair, and sebaceous glandsⁱ  XSmall exocrine glands that open on skin and hair follicles and release a waxy substance called sebum. . Sufficient vitamin A intake results in optimal sebum production, which helps moisturize the scalp for healthy hair growth (1).

Another study shows that deficiency of vitamin A may lead to alopecia (2).

Although it is important to get enough vitamin A, excess of it can also reduce the number and length of hair follicles and lead to hair loss (1).

Foods Rich In Vitamin A (3)

• Sweet potatoes
• Carrots
• Milk
• Spinach
• Dried apricots
• Mangoes

2. B Vitamins

i. Vitamin B12

According to Dr. K. Harish Kumar, MD, DVL, vitamin B12 plays a vital role in the formation of red blood cells. These red blood cells carry oxygen to all body tissues, including the hair (4).

Studies show that there is potential for optimal hair growth if the vitamin B12 levels are within the normal range (5).

Foods Rich In Vitamin B12 (4)

• Cheese
• Whey powder
• Milk
• Yogurt

ii. Biotin

Biotin is known as the “hair growth vitamin.” It is one of the 12 vitamins in the vitamin B family.

A study was conducted to evaluate the efficacy of biotin in hair growth. Results showed that 18 patients with poor hair and nail growth exhibited improvement after receiving biotin (6).

Biotin deficiency may cause uncombable hair among children (6). Other symptoms include thinning hair and hair loss all over the body (7), (8).

Lancy, a blogger, tried biotin for hair growth and shared her experience. She writes, “I took biotin supplements for one month and I could notice a lovely change in my hair texture (i).”

However, there is a lack of data regarding the effectiveness of biotin among healthy individuals.

• Avocados
• Eggs
• Peanut butter
• Yeast
• Sunflower seeds
• Sweet potato
• Cauliflower
• Raspberries
• Bananas
• Walnuts
• Almonds

iii. Folic Acid (Folate)

Folate is a water-soluble B vitamin. Folic acid is a fully oxidized form of vitamin that is used in dietary supplements.

It helps generate red blood cells, which ensures transportation of oxygen to all the tissues, including those that build hair. It is responsible for rebuilding hair follicle cells and preventing graying of hair and hair fall (9).

Foods Rich In Folate (9), (10)

• Kale
• Spinach
• Black-eyed peas
• Lettuce
• Brussels sprouts
• Green peas
• White beans

Foods Rich In Niacin (12)

• Marinara spaghetti sauce
• Brown rice
• Peanuts
• Potato
• Sunflower seeds

3. Vitamin C

Vitamin C is also known ascorbic acid. It is a water-soluble mineral that is naturally present in some foods. It is an important physiological antioxidant that regenerates other antioxidants within the body, including vitamin E.

Studies are ongoing to find out if vitamin C restricts the damaging effects of free radicals through its antioxidant content that helps reduce oxidative stress, which can prevent or delay the development of certain cancers (13). This blockage of oxidative stress can also reduce the aging of hair (14).

In addition to that, studies show that insufficient vitamin C intake can cause scurvy. As a result, there may be bleeding around hair follicles and corkscrew hairs (15).

Vitamin C is also known to aid in protein synthesis, which in turn boosts collagen production (16). Collagen is an essential hair-building protein that promotes longer, thicker hair.
Therefore, add a lot of vitamin C in your diet for healthy hair follicles and overall hair and scalp health.

It plays an important role in calcium regulation, healthy immune function, and cell growth.
Research shows that decreased levels of vitamin D may cause alopecia areata. Its deficiency may disturb the normal postnatal hair follicle cycle (17).

Another study has found that the topical application of vitamin D analog (synthetic vitamin D ointment that you rub on your skin) can treat alopecia areata (18).

Vitamin D supplementation can be therapeutic for patients with alopecia areata, female pattern hair loss, or telogen effluviumⁱ  XTemporary hair loss that happens after a traumatic or stressful event like surgery, childbirth, or a serious illness. (17). However, further studies with larger groups of patients are required to evaluate the role of vitamin D supplementation in alopecia.

The actual relationship between vitamin D and hair growth is unknown. Although our body produces vitamin D naturally after exposure to sunlight, you can find it in the following foods.

Foods Rich In Vitamin D (19)

• Cheese
• Milk
• Yogurt

5. Vitamin E

Vitamin E is a group of fat-soluble compounds with rich antioxidants. It exists in various chemical forms, of which tocopherol is the only form that can be consumed by humans.

A study was conducted to investigate the effect of tocopherol on 21 subjects with hair loss. The results showed that there was a significant improvement in the number of hairs on the participants at the end of the 8-month trial period. This is because the antioxidant activity of tocotrienolsⁱ  XChemicals from the vitamin E family with antioxidant properties that are commonly found in vegetable and rice oils. helped reduce oxidative stress in the scalp (20).

Foods Rich In Vitamin E (21)

Besides these five vitamins, there are two minerals that can also help your hair grow. Check them out below!

2 Essential Minerals For Hair Growth

1. Iron

Research shows that 30% of women experience persistent hair shedding and reduced hair volume due to depleted iron stores in the body before the age of 50 (22), (23).

Iron deficiency is seen as one of the causes of hair loss in women with female pattern hair loss (24), (25), (26).

According to a retrospective study conducted with 343 participants diagnosed with alopecia, hemoglobin was requested by 338 (98%) patients and ferritin by 304 (88%). Of these, 20(5.8%) and 83 (24.2%) patients had anemia and iron deficiency, respectively.

There are also some macronutrients that you can include in your diet to increase your hair growth. Find out more about them in the next section.

Essential Macronutrients For Hair Growth

Although dietary protein is essential for the body’s keratin production, specific amino acids within the protein, such as cysteine, are particularly important for hair growth.

Cysteine is one of the key building blocks of keratin, and it helps create disulfide bonds, which strengthen the hair. Adequate cysteine intake can positively impact the quality and growth of hair (34).

Foods Rich In Cysteine (35)

• Almonds
• Figs
• Cow milk
• Tofu
• Quinoa
• Salmon
• Lamb

• Canola oil
• Chia seeds
• Walnuts
• Soybeans

Foods Rich In Omega-6 Fatty Acids (38)
