Do Prenatal Vitamins Promote Hair Growth? What You Need to Know

Oct 23, 2024

It’s already well-known, especially for mothers, that during pregnancy the frequency of hair growth increases. Many believe that’s because of taking prenatal vitamins, which cause the hair to grow. But do prenatal vitamins promote hair growth?!

You can find the answer to this question in the article below. You’ll also learn about the key nutrients involved in general hair growth and alternatives for them too.

Do Prenatal Vitamins Promote Hair Growth? 

Prenatal vitamins are a very important part of pregnancy and have many benefits for health treatment. For that reason, many myths are known about these nutrients as well. Prenatal vitamins are specifically formulated to support a growing baby and mother’s health, not hair growth. So taking prenatal vitamins during pregnancy doesn’t necessarily promote hair growth. If you want your hair to look healthier and thicker, there are many other effective ways to achieve that.

The Reality:

Do you know the main purpose of taking prenatal vitamins during pregnancy? Guarantee, it’s not hair growth, right? Prenatal vitamins are created to support your health and your baby’s proper development. There’s no evidence that prenatal vitamins will directly make your hair grow. However, some of these vitamins include nutrients that can indirectly affect your hair’s health. 

For example, iron and vitamin D have been shown to be beneficial for hair growth. Prenatal vitamins also include B vitamins, which are responsible for healthy cell growth which may consist of skin and hair as well. So indirectly, they may support hair to grow. 

Temporary Hair Growth During Pregnancy:

When you’re pregnant many things change in your appearance as well as in your body.  Most of them are temporary and will go back to an older shape or condition after childbirth. During pregnancy, many women notice a slight improvement in the quality and length of their hair. It typically grows better, is shinier, and hardly falls out. Do prenatal vitamins promote hair growth? No, the reason is hormones which make your hair grow faster and healthier. The estrogen level increases throughout pregnancy and that supports your hair to look more healthier. However, these hair changes are usually temporary.

Key Nutrients in Prenatal Vitamins That Impact Hair Health

Biotin (Vitamin B7):

Biotin, also called vitamin B7 is necessary for the body to metabolize fats, protein, and carbohydrates, and consume energy and nutrients from them. Biotin deficiency often leads to hair loss and skin problems, and therefore supplements can aid hair growth

Prenatal vitamins taken during pregnancy may consist of B vitamins, including Biotin to support the baby’s healthy development. So when using those vitamins, your hair may also become healthier and stronger.

Iron:

Iron is the nutrient that helps your body to produce hemoglobin, which is the protein in red blood cells. Hemoglobin carries oxygen to the body’s cells to help them to grow or repair themselves. This also includes body cells which help your hair to grow. 

Iron also improves blood circulation, including blood supply and lymphatics. These vessels nurture hair follicles, and growth and help nutrient delivery. Loss of blood supply to hair follicles can lead to some forms of hair loss. So always be aware of how balanced the iron is in your body. 

Vitamin D:

Some researchers have found that vitamin D interacts directly with hair follicles. When your body has enough vitamin D, it helps hair to grow and function properly. This also supports the growth/anagen phase, where thick hair is produced. Vitamin D also has its role in the creation of new hair follicles. Hair follicles are tiny pores from where new hair grows. Newly grown follicles tend to maintain hair thickness and prevent existing hair from falling out. So maintaining vitamin D balance is important for your healthy hair. 

Folic Acid:

Folic acid is an important vitamin for maintaining healthy hair because it supports the production of keratin which is a protein that creates the hair structure. Insufficiency of folic acid can cause hair thinning and loss, that’s why it is always an important ingredient while making hair growth products. 

Folic acid helps the development of new cells in organs, which then turns into healthy cell division and eventually positively affects hair growth. To maintain a healthy cycle for your hair growth, always make sure to intake enough folic acid needed for your body.

Prenatal Vitamins vs. Biotin for Hair Growth 

Biotin Supplements:

Do prenatal vitamins promote hair growth? Is it the best solution for your hair?! Let’s see:

If you’re comparing prenatal vitamins vs biotin for hair growth, always consider the body they are going in. It mostly depends on your needs and goals. Biotin is known to support existing hair growth and increase its thickness, which will lead to decreased hair fallout.

Therefore prenatal vitamins promote healthy blood circulation and oxygen delivery to your scalp which affect hair growth. In essence, biotin is often known to improve the strength and thickness of hair, while prenatal vitamins, especially folic acid, support general cell growth, indirectly benefiting hair growth too.

Prenatal Vitamins for Hair Health:

Prenatal vitamins are something that is necessary mostly for every pregnant woman to consume. They consist of many different nutrients that positively affect processes in your body, including hair growth. But how do prenatal vitamins promote hair growth?!

Many compare biotin vs prenatal vitamins for hair growth, when in reality, sometimes biotin is something that is found in some prenatal vitamins. For example, in B vitamins, which are the nutrients of prenatals. Biotin is vitamin B7, which as we already discussed, has a very positive impact on hair growth. But it doesn’t mean that prenatal vitamins are specifically targeted to promote healthy hair. Their purpose is to maintain the mother's health and support the baby's development. 

Which is Better for Hair Growth?

When choosing prenatal vitamins vs biotin for hair growth, always consider individual needs and the body it has to go in. If your goal is to have healthy hair or nails and don’t have the special need for other nutrients, in this case, biotin can be the best option for you.

But if you’re pregnant or trying to be, then prenatal vitamins are a better choice for you. They contain biotin (the best prenatal vitamins for hair growth), which will support your hair’s health, and therefore include some other nutrients that will become necessary during your pregnancy. But before making a decision, consider consulting with your doctor to be more sure of your body’s needs. 

Can Prenatal Vitamins Improve Hair Growth for Non-Pregnant Women? 

Possible Side Effects for Non-Pregnant Women:

Do prenatal vitamins promote hair growth? Again, directly no. Prenatal vitamins shouldn’t be taken if you’re not pregnant. If you need any type of nutrients or have some other goal for your body to achieve, there would be many other effective ways for it rather than accomplishing it with prenatal vitamins. This is because unnecessary consumption of prenatal vitamins can cause much damage, as your body will be producing excessive iron and folic acid, which can cause severe liver, stomach, or nerve damage. So don’t face these risks with your own prescribed routine, talk to your doctor and precise what is best for you.

Hormonal Effects on Hair Growth During Pregnancy 

Increased Estrogen Levels:

When your pregnancy journey starts, your body is expected to go through many changes, including hormonal ones. During pregnancy, the level of hormone estrogen is increasing. It supports hair to remain in a growing also called anagen phase and stimulates your hair growth. Because of that, while you’re pregnant expect to have a full and shiny head of hair. 


That is the reason why pregnant women don’t usually go through hair loss, estrogen is responsible for it. But it’s temporary, after pregnancy it may change.

Postpartum Hair Loss:

Postpartum hair loss is a common condition that appears after 3 months of having the baby and may last up to six months. It’s a normal part of the after-pregnancy process and is only temporary, as it was hair growth during pregnancy. For most people, the hair goes back to the condition it had before getting pregnant.

The reason behind excessive hair loss after childbirth is the changes in hormonal balance, specifically in estrogen. During pregnancy, this hormone level increases which positively impacts hair growth and causes the body to keep the hair it would usually lose. After the baby is born, estrogen levels decrease to its previous condition and the extra hair falls out.

When you intake collagen or other kinds of proteins, your body tends to break them down into amino acids that can also be used to build up stronger hair proteins and strengthen the skin that contains your hair roots. 

A Balanced Diet:

Including a balanced diet in your daily routine can be beneficial not only for your hair but for the overall health of your body.
