Vitamin B is often called the “beauty vitamin” because it promotes healthy hair growth, nourishing hair follicles with oxygen and nutrients.

Specific B vitamins, such as B3, B5, B6, and B12, are essential for hair health and preventing hair loss.

Riboflavin, biotin, folate, and vitamin B12 deficiencies are known to cause hair loss.

Good dietary sources of B vitamins include meat, fish, eggs, dairy products, whole grains, and leafy green vegetables.

Before we get into our article, we should say that there is currently no scientific evidence to show that B-complex helps hair growth or is effective in treating androgenic alopecia (male pattern baldness).

What is Vitamin B?

B vitamins are a group of water-soluble vitamins that are important for many bodily functions, including the health of your hair. They help to nourish and strengthen hair follicles, promote healthy circulation to the scalp, and support the production of healthy hair cells.

B vitamins can help to reduce stress, which is a common cause of hair loss. 

While all B vitamins are important for hair health, some are particularly beneficial for preventing hair loss and promoting hair growth.

If you’re looking to incorporate more B vitamins into your diet to improve the health of your hair, many foods are rich in these essential nutrients. However, if you’re experiencing significant hair loss or have a medical condition that affects your nutrient absorption, you may benefit from taking B vitamin supplements.

Hair loss is a common problem that affects both men and women. It can be caused by a variety of factors, including genetics, hormonal imbalances, stress, and nutritional deficiencies.

It has been scientifically proven that riboflavin, biotin, folate, and vitamin B12 deficiencies cause hair loss.

One of the most common causes of hair loss is a deficiency in B vitamins. B vitamins play a crucial role in maintaining healthy hair, as they are involved in the production of keratin, a protein that makes up the structure of hair.

B vitamins also help to improve circulation, which is important for delivering nutrients and oxygen to the hair follicles.

Several B vitamins are particularly important for hair health, including:

  • Biotin (B7): Helps to strengthen hair and prevent breakage.
  • Niacin (B3): Improves circulation to the scalp, which can help to promote hair growth.
  • Vitamin B6: Helps to regulate hormones, which can be a factor in hair loss.
  • Vitamin B12: Helps to prevent hair loss by promoting the production of red blood cells, which carry oxygen to the hair follicles.

Vitamin B5, also known as pantothenic acid, is important for maintaining healthy hair follicles. It helps to nourish hair follicles and improve their function. Vitamin B5 also helps to prevent hair thinning and breakage.

If you are experiencing hair loss, it is important to make sure that you are getting enough B vitamins in your diet. Good dietary sources of B vitamins include meat, fish, eggs, dairy products, whole grains, and leafy green vegetables. If you are not getting enough B vitamins from your diet, you may want to consider taking a B vitamin supplement.

It is important to note that while B vitamins are essential for hair health, they should not be relied on as a standalone treatment for hair loss or other hair conditions.

Although Riboflavin does not affect the hair, Riboflavin deficiency causes hair loss. This is because Riboflavin deficiency disrupts the body’s iron metabolism and creates stress in the body.

Riboflavin, or vitamin B2, can be naturally sourced from foods like dairy products, eggs, lean meats, fish, leafy vegetables, nuts, seeds, whole grains, mushrooms, avocado, and legumes.

Riboflavin is a heat-stable vitamin. You can cook any food containing riboflavin at any temperature you want.

It is known that vitamin B6 increases hair growth and accelerates hair growth.

Vitamin B6 also has beneficial effects on the scalp. B6 makes the scalp more resistant. Additionally, it increases blood circulation, allowing the scalp to better supply oxygen to the hair follicles.

In 2007, a study by the British Journal of Dermatology found that using Vitamin B6, zinc, and azelaic acid together can stop 90% of testosterone’s harmful effects, which lead to hair loss through DHT in hair follicles.

Vitamin B6, also known as pyridoxine, can be naturally sourced from foods like poultry, fish, lean meats, bananas, whole grains, nuts, and legumes.

Vitamin B7 (Biotin)

Biotin, also known as vitamin B7, is a popular supplement for hair growth and health. It helps with the production of keratin, which is essential for healthy hair growth. Biotin also helps improve the elasticity of hair strands, making them less prone to breakage.

Folate or vitamin B9 functions as an enzyme or cosubstrate and stabilizes DNA synthesis. Vitamin B9 supports the body’s blood cell production.

Regular consumption of vitamin B9 supports healthy hair and nail development. Since vitamin B9 supports healthy cell growth, it nourishes the skin tissues on the scalp, as well as the cells in your hair follicles and nails.

Vitamin B9 alone has a limited role in hair growth. Vitamin B9 creates a synergistic effect when combined with other vitamins and hair growth methods.

Vitamin can be naturally sourced from foods like leafy greens (e.g., spinach, kale), legumes (e.g., lentils, beans), citrus fruits, avocados, and fortified cereals.
