7 benefits of folic acid for hair growth

Updated: Apr 12, 2021

What does folic acid do?

Folic acid is primarily responsible for healthy cell growth. These cells are found inside your skin tissues as well as in your hair and nails. Such effects on your hair has spurred interest in folic acid as a possible hair-growth treatment measure.

Additionally, folic acid helps keep red blood cells healthy.

Folic Acid is the synthetic form of folate, a type of B vitamin. When found naturally in foods, this nutrient is called folate.

The folate in fortified foods and supplements is manufactured and is called folic acid. Although known by two different names, folate and folic acid function in the same way.

What does the research say?

Research for birth:

Research has shown that taking folic acid before getting pregnant and in early pregnancy lowers the risk of having a baby with certain birth defects.

This research finding led to the advice that all women who can get pregnant should take 400 micrograms of folic acid daily. In order to learn more, CDC continues to conduct folic acid research.

You may have noticed that many women who are pregnant experience healthier hair growth. This is likely due to folic acid and not the pregnancy itself.

More importantly though, folic acid helps keep both mom and baby healthy, while also preventing potential neurological birth defects. Your doctor will likely suggest a daily prenatal vitamin that includes folic acid.

Research for hair growth:

Research establishing folic acid as a hair-growth method is minimal. One study Trusted Source, published in early 2017, looked at 52 adults with premature graying.

The researchers behind the study found deficiencies in folic acid and vitamins B-7 and B-12. However, additional controlled studies are needed to determine whether folic acid alone can help with hair growth.

How much to take

The recommended daily dosage of folic acid is 400 micrograms (mcg).

If you don’t get enough folate from whole foods in your diet, you may need to consider supplementation.

A lack of folic acid may cause symptoms, such as:

  • headaches

  • irritability

  • pale skin

  • pigmentation changes in your hair and nails

  • severe fatigue

  • soreness in your mouth

  • thinning hair

If you’re not deficient in folate, you don’t have to take a folic acid supplement for healthy hair. Any more than 400 mcg a day won’t make your hair grow faster. In fact, taking too much folic acid can be unsafe. A folic acid overdose can occur when you take too many supplements or eat a high amount of fortified foods, but not if you eat folate in natural foods. Taking more than 1,000 mcg per day can lead to nerve damage.

While folic acid is technically a B vitamin, it’s not included in many vitamin B complex supplements. You may instead need to look for the nutrient in multivitamins. It’s also available as a separate supplement. Make sure the supplement has 100 percent of the daily value you need.

Folic Acid Benefits:

  • Folate helps in metabolizing protein, fat, and carbohydrates successfully.

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.


A 2016 study analyzed a number of randomized control trials and found that Folic acid supplements were associated with a 10 percent decrease in strokes and 4 percent decreases in cardiovascular diseases


Folic acid may help counter act hearing loss. A 2014 study found while working with female mice. Human studies on genetic diseases have also shown a potential correlation between hearing loss and folate though further studies are needed to better understand how and why the two are linked.


Studies dating as far back as 1984 were able to find evidence that Folic acid can reduce gingivitis.


Folate or folic acid helps your body build healthy cells and tissue. So, if you’re trying to get longer hair, getting adequate amounts of the B vitamin should be part of a holistic plan of action.

  • The proper synthesis of nutrients helps in keeping the follicles nourished. This helps add shine and volume to your hair.

  • Deficiency of folic acid is the prime cause of premature graying. Hair discoloration happens as a result of a process called megaloblastic anemia, where the production of red blood corpuscles increases abnormally. Regular consumption of folic acid helps to normalize this over production of the red blood cells.

  • As folic acid speeds up cell division, it helps boost hair growth.
