Hair fall can be a result of several factors. Genetics, aging, stress, and nutritional deficiencies are a few of them. Studies show that nutritional supplements play a significant role in improving hair health, especially Riboflavin or Vitamin B2. Here’s all you need to know about Vitamin B2 benefits for hair health.

What is Riboflavin?

Riboflavin, commonly known as Vitamin B2, is one of the eight B complex vitamins. It is a water-soluble vitamin important for collagen production in the body. An antioxidant in its true sense, Vitamin B2 is needed for cell development, fat metabolism, and energy production in the cells; properties that make it a crucial element for hair health.

Benefits of Vitamin B2 for Hair

It is an important nutrient for the body. It functions in a complex manner and helps reduce hair fall and improve hair health. Here are some of the vitamin B2 benefits for hair health: 

Increased Energy Levels 

Vitamin B2 is involved in the metabolism of macronutrients, namely carbohydrates, fats, and proteins. Its primary role is to effectively convert food into energy that is used by the hair follicles to support hair growth. As vitamin B2 deficiency is directly linked to increased hair fall, the supplements act as a direct way to curb the issue.

Improved Blood Circulation

Vitamin B2 plays a crucial role in the production of red blood cells, which are responsible for transporting oxygen throughout the body. The vitamin is also important for the dilation of blood vessels. These factors contribute to increased blood circulation in the body. An increased nutrient supply to the hair follicles helps improve hair growth.

Regulation of Thyroid Levels

The thyroid is an important hormone for the body. It is essential for the maintenance and growth of hair follicles. Studies establish a correlation between vitamin B deficiency and thyroid dysfunction. Thus, optimum levels of Vitamin B in the body help in thyroid regulation, which in turn promotes hair growth and health.

Tissue Repair

Vitamin B2 is important for the synthesis of collagen, a protein that is the primary part of all connective tissues in the body. Studies show that higher collagen levels aid in tissue repair thereby making the hair strands healthier and less prone to breakage and split ends. 

Improved Digestive Health

Riboflavin is important for nutrient breakdown and its effective absorption. The improved digestive health allows better assimilation of nutrients in the body, which are transported to the hair follicles through enhanced blood circulation. This nourishes the hair follicles from within, promoting hair growth.

How to Source Vitamin B2?

The best way to source Vitamin B2 for hair growth is through healthy food and a balanced diet. The recommended dietary allowance of Vitamin B2 is 1.3mg daily for men and 1.1mg for women. The required levels go up during pregnancy and lactation. Here is a list of Vitamin B2-rich foods:

  • Dairy products like milk, yogurt, and cheese
  • Fortified cereal and bread
  • Eggs
  • Chicken breast
  • Fish like salmon
  • Almonds
  • Vegetables like spinach, broccoli, and cauliflower
  • Sunflower seeds

Vitamin B2 can also be sourced through oral supplements. These are available over-the-counter and are effective in restoring Vitamin B levels. 


Vitamin B2, or riboflavin is an essential nutrient for the body. This vitamin is made up of two coenzymes that are responsible for the generation of new cells in the body. This constantly pushes the hair follicles into the growth stage, contributing significantly to hair health. Optimum levels of the vitamin also improve hair texture through increased collagen levels. A healthy diet is the best way to maintain optimum levels of the nutrient. One can also opt for B-complex supplements or Vitamin-enriched hair care products for best results.
