Can vitamin B complex prevent hair fall or even baldness? And should you take it as artificial supplements, or is it better to meet your body's requirements through vitamin B complex-rich food? These are some of the most common questions hair loss patients ask.

In this article based on his educational video, Dr. John Watts — dermatologist, trichologist and hair transplant surgeon in Hyderabad who has performed over 2,000 hair transplant procedures — explores the complete role vitamin B complex plays in hair growth and body metabolism.

What is vitamin B complex?

Vitamin B complex is a group of 8 different types of B vitamins. They are water-soluble vitamins. According to Dr. Watts, these vitamins help in cell development, keep the red blood cells (RBCs) healthy and ensure they supply enough micro-nutrients to the scalp needed for hair growth.

"The vitamin B complex helps in laying a strong foundation for the hair roots and helps the hair cell regenerate," said Dr. John Watts.

Which B vitamins matter for hair?

Not all 8 types of B vitamins play a role in hair growth. Only four are actively involved: B2 (riboflavin), B3 (niacin), B7 (biotin) and B9 (folate or folic acid).

Supplements or natural food?

Vitamin B complex can be taken as artificial supplements or obtained from food. "Usually, hair transplant surgeons or dermatologists prescribe tablets for B complex deficiencies. They are also available as Over the Counter (OTC) drugs," informed Dr. Watts. However, he stresses that natural sources of B complex vitamins are more important and preferable.

Best natural food sources of B vitamins

- Milk products: Curd and cheese are a good source of biotin. Biotin is also found in eggs, fish (especially salmon and tuna), almonds, sunflower seeds, bananas, apples, sweet potatoes and spinach.
- Leafy vegetables: Spinach and coriander supply folates. "They help in hair growth," said Dr. Watts.
- Eggs: A rich source of B12, which helps produce RBCs. "It ensures hair roots get enough oxygen," he informed.
- Fish: Besides omega-3 fatty acids, fish is rich in B3 and B12 — both important for hair health.
- Dry fruits: Rich in vitamin B1, which helps in the regeneration of nerve cells and hair cells.
- Avocados: A rich source of B2 and B3, but some people are allergic to them and should be cautious.
- Whole grains: Wheat, millet and oats are rich in vitamin B complex. Regular consumption helps reduce hair fall and strengthens hair.

Deficiency and excess: what to watch for

A deficiency in B complex may lead to hair fall. "One must immediately start taking supplements or food rich in vitamin B complex," Dr. Watts advised.

On the other hand, taking excess B complex supplements may cause false readings in blood test reports. "Those taking artificial B complex vitamins, the urine may turn yellowish but there is nothing to worry about," he reassured.

The bottom line

Vitamin B complex — especially B2, B3, B7 and B9 — supports healthy hair roots and cell regeneration. A balanced diet with milk products, eggs, fish, leafy greens, dry fruits and whole grains can cover most of your needs. If you suspect a deficiency is behind your hair fall, get it confirmed before reaching for supplements.
