What Is Folic Acid?

Vitamin B9 or folate is an essential nutrient vital for the efficient functioning of the human body (1). It is a water-soluble vitamin whose deficiency can lead to a host of health problems, which may include hair loss and stunted hair growth (2), (1).

It is found in plenty of foods and green leafy vegetables and is an easy nutrient to come by when looking for natural solutions for hair loss.  Folic acid is the synthetic form of folate and is available only as supplements and fortified foods.

A study conducted on 1285 women found that only 13.1% of women take folic acid supplements overall, out of which only 65.3% of them take it regularly. It was further noted that 91.1% of women were not aware of the correct dosage and 43% did not know the role folic acid played in the body.

Regular consumption of folate or folic acid facilitates tissue growth and also allows cells to function smoothly (1). The unhindered growth of tissues is essential when concerned with skin, nail, and hair growth.

The vitamin has been shown to boost healthy cell generation, and therefore, it can stimulate natural hair growth in both men and women. A recent study has established that folate levels tend to be low in people with alopecia areata (3).

Here are the different ways in which folate can benefit your hair:

  • Folate helps in metabolizing protein, fat, and carbohydrates (1). It helps to cater to the absorption of different nutrients within the human body. In this way, the hair follicles receive their required nutrition from the consumed foods.
  • It helps in the proper synthesis of DNA nucleotides and amino acids (4). These help in hair nourishment by strengthening the follicles and add shine and hair thickness.
  • The deficiency of folic acid may cause premature graying (5). Hair discoloration happens as a result of a process called megaloblastic anemia, where the production of red blood cells increases abnormally. Regular consumption of folic acid helps to normalize this overproduction of the red blood cells.
  • As folic acid speeds up cell division, it can help boost hair growth.

However, it is important to note that there is no scientific evidence that links folic acid directly with hair growth. All the purported benefits listed above are based on research done on other functions of folic acids.

Biotin and folic acid are two vitamins that are often associated with hair growth and overall hair health. But is one of them better for hair growth than the other? Let us find out.

Biotin Vs. Folic Acid For Hair Growth

Biotin is often promoted for its hair, skin, and nail benefits, whereas folic acid is not as popular for the same. However, when it comes to hair growth, both of them have limited studies that prove their effectiveness. Moreover, research states that biotin can only aid hair growth if you have a biotin deficiency, which is rare in individuals who follow a balanced diet (6). Since research on both of these nutrients is limited, it is best to consult your doctor before consuming either of them.

King Bril, a male health beauty and fitness YouTuber, observed the effect of biotin supplements on his hair: “For the first month of using it, I didn’t see any growth at all, and I couldn’t understand why it wasn’t working. Looking back, I know it was because I wasn’t drinking [enough] water. The next month I decided to give it another try, and I drank a lot more water. I think this has done wonders for my hair (i).”

So, can you use folic acid with biotin or any other nutrient for optimal hair growth? Check out the next section to find out.

 How To Use Folic Acid For Hair Growth

While folate (and folic acid) is good for your hair, it alone cannot help stimulate hair growth.

Most hair care supplements boast of having biotin in them. But what does science say about it? While a few cases of biotin deficiency has resulted in hair loss, there isn’t enough research to support that it helps with hair growth. It does help in improving hair quality.

A study showed that when supplied with biotin, hair and nails had improved quality, which they lacked due to a biotin deficiency. In the same study, people with alopecia were treated with biotin, which improved it (2).

While there isn’t much research that suggests folic acid and biotin work together, they are often used together in vitamin B complex tablets. These vitamins are hair food that will boost the rate at which your hair grows. You will notice a visible improvement in hair quality within a couple of months of starting the supplements.

However, it is vital that you consult a healthcare professional before you start taking any multivitamin supplements. Eggs, nuts, whole grains, meat, and legumes are food sources that are rich in biotin (7).

2. Food Sources Of Folate

If you are skeptical about supplements, you can always turn to natural food sources of the vitamin. Not only will you be consuming healthier foods, but you will also be less likely to incur side effects that come with supplements.

The best sources for folate are usually fruits and green leafy vegetables (8).  These include citrus fruits, dried beans, and leafy green vegetables like spinach. Capsicum, French beans, broccoli, and chilies are also rich sources of folic acid (8). Some other foods fortified with this essential nutrient include bread, cereals, rice, pasta, flours, and other multigrain products. Check out this article to see which foods contain folate.

Another excellent source of folate is orange juice. However, drink it in moderation as it is high in natural sugar.

3. Folic Acid And Zinc For Hair Growth

If you have a hair loss problem that is stemming from the deficiency of zinc, increasing your intake of zinc may boost hair growth (2). The use of pyrithione zinc showed an increase in hair growth (9). However, you must always get a proper diagnosis before you start taking any mineral-rich supplements.

Eggs, nuts, oysters, spinach, chickpeas, and sweet potatoes are some great natural food sources of zinc that you can add to your diet (10).

Folic acid is a synthetic version of vitamin B12 that is popularly available as supplements and in fortified foods. Studies suggest that regular consumption of folic acid may boost hair growth, help with hair strengthening, and hair follicles, and add shine and volume to the hair. Since folic acid alone cannot produce visible results, you can eat it with biotin supplements to combat hair fall. Additionally, you can eat foods such as broccoli, beans, pasta, or multigrain products to obtain folic acid for hair growth. Consult a doctor before taking any nutritional supplements.
