How does riboflavin deficiency affect hair growth?

Asked 2 years ago

My doctor recently told me that I run the risk of developing a riboflavin deficiency. Apparently one of the side effects is loss of hair. Why?

Riboflavin or vitamin B2 is a water-soluble vitamin that's part of the B complex vitamins. Riboflavin is needed for collagen production, which leads to healthy hair so a deficiency would interfere with that. Additionally, riboflavin plays a crucial role in activating niacin and vitamin B6, both needed for healthy hair. So a deficiency in riboflavin would lead to less of these nutrients, thus interfering with hair growth.
