Folic Acid for Hair Loss: Why It’s Used in Hair Loss Supplements

Folic acid supplement for hair

We all lose hair on daily basis, but for some the rate of hair loss does not tally with the rate of hair growth and this results in hair loss.

Folic acid is a B vitamin that is needed by the body for the generation of new cells. This vitamin is needed in sufficient quantities on a daily basis, and an average adult requires around 400 micrograms per day2.

Folic acid is most needed when a woman is pregnant as it aids in the prevention of birth defects that can potentially harm the baby’s spine and brain.

Folic acid, also known as folate, when not present in sufficient amounts results in several conditions, one of which is poor hair growth. A study conducted at the University of Guelph (Canada) saw that hair loss can be treated through incorporating more folic acid in the diet with results being evident in a short period of time. The vitamin helps renew the cells that help with the growth of healthy hair3.

In the ‘Best vitamins for hair growth’ article, you will find folic acid along with several other B vitamins including Pantothenic acid (vitamin B5) appear in most hair growth supplements.

Two crucial roles played by folic acid in promoting hair growth are that of helping nutrients to reach the hair and encouraging cell division around the hair follicles. Hair growth largely depends on frequent cell regeneration in the follicle, so a consistent supply of folic acid promotes healthy hair growth.

Folic acid is readily found in numerous citrus fruits, natural juices, dark leafy green vegetables and dried beans. Your physician may prescribe folic acid supplements and vitamins if you consult with them in regards to your current diet and how you can make modifications that ensure that you are getting more folic acid.

If you’re thinking about using a folic acid supplement to increase your hair growth, you might be better off using a supplement containing folic acid and many other nutrients for hair growth.
