Biotin For Hair Growth: Will It Work?

Biotin is a form of B vitamin that helps to strengthen the hair and nails of the body. Researchers have also found that biotin deficiency can lead to hair loss and can weaken its strength.

At the same time, people also think that having a biotin supplement can help regrow hair.

Hence till now, no evidence is available that can prove this claim; still, many people have said that they have benefits with these types of supplements.

In this regard, we have provided all the information on biotin and its effect on hair growth.

What Is Biotin Actually?

Biotin Help Regrow  Hair

As we have discussed earlier, biotin is a nutrient in the form of B vitamins that occurs naturally in humans as well as in other organisms.

It supports various bodily functions, such as the nervous system and liver, as well as strengthens the hair and nails. These vitamin B7 also help in improving the metabolism while transforming your food into energy and managing your gene activities as well.

Some research has also found that reduced biotin can cause various health issues, including hair fall. The deficiency of biotin can weaken the hair, and people start shedding their hair which is eventually a major health issue.

But the question here arises, can fulfilling the need for biotin help regrow the hair as it was before?

What Is The Relation Between Biotin And Hair Growth?

As you know, biotin plays an important role in strengthening hair and other similar organs like nails. At the same time, you must also understand that its decreased content in the body may also cause hair falls.

You have to understand that these B vitamins help in the production of keratin, a type of protein that forms the nails, skin, and hair of the body.

In this regard, it is easy to say that increasing the biotin intake can help in better hair growth. Here, you have to understand that there is a difference between promoting hair growth and preventing hair loss.

Till now, scientists have found very little evidence that claims that biotin can help in better hair growth.

Additionally, hair fall can be caused due to various other reasons, which could be due to stress and anxiety.

Additionally, hair loss can also be caused due to medications or a person who has gone through surgery. In such cases, it can’t be cured by solving the problem of bone deficiency.

Some research has also found that Vitamine B7 can support hair growth only if you have lost your hair due to biotin deficiency. To understand its functionality better, it is essential to know the reason behind the biotin deficiency.

What Happens When You Suffer From Biotin Deficiency?

Biotin deficiencies are one of the rare symptoms that are caused by a decrease in the production of keratin, which is essential for hair and nails.

As a result, the quality of your hair tends to decrease, which leads to weakening its strength. The symptoms are so rare that even having enough vitamin B supplements is unable to revive hair growth.

Other than hair loss, you can also find developmental delays in children, and poor coordination between body parts can be observed.

Some people may also have conjunctivitis or dry eyes or feel fatigued and drowsiness more often. The risk of diarrhea and vomiting may also increase due to fungal infection caused by biotin deficiency.

Now, coming back to the topic, biotin deficiency can be cured by following a proper diet. To do so, you must include food items that are rich in biotin content to reduce the risk of such deficiency.

Additional research has also found that the intake of food that contains vitamin B7 can also help in the growth of hair.

Here, you have to note that we have mentioned additional supplements that are used to boost the biotin intake in the body. Instead, we recommend that you be inclined towards natural ingredients that are helpful in boosting vitamin B in the body.

How Biotin Can Help In Hair Growth?

When you suffer from biotin deficiency, it can result in hair loss over time; taking biotin supplements can help you nourish your hair follicles and regain lost hair.

One of the main compounds in your body responsible for hair health is Keratine, and when you are deficient in biotin, it can reduce the production of keratin, resulting in hair loss.

Here are some specific benefits of taking Biotin supplements your healthy hair growth:

➡️ Improves Your Cellular Functions

When it comes to taking biotin, it is essential to know that biotin is an important compound for your body and is responsible for protein and carbohydrate synthesis.

When you start taking biotin, your body starts to produce more keratin, which increases the nutrition supply to hair follicles.

Make sure you are taking only 30 to 100 mcg (micrograms) of biotin every day, as your body rejects extra biotin from your body, and excessive dosage can make it ineffective.

➡️ Promotes Follical Health

Certain studies have been conducted on measuring the effects of biotin on hair growth, and it was proved that it has some positive effects on hair follicles.

Keratin synthesis, which weakens as a person grows bald, biotin improves the synthesis by promoting keratin production and cellular function. This can lead to regrowth of hair and strengthening the hair follicles as well.


You might have understood that biotin is an important nutrient that is present in the body in the form of vitamin B7.

These nutrients are essential to produce keratin protein that helps to strengthen the hair as well as nails. Additionally, biotin also promotes energy and helps to regulate various bodily functions.

But in rare cases, biotin deficiency can occur due to various issues which may lead to hair loss. In such cases, intake of vitamin B7 can help in the healthy growth of hair, which can only be fulfilled naturally rather than by having biotin supplements available on the market.
