Sourced from various foods, such as haddock, eggs and beef, vitamin B12 is water-soluble. This means it can dissolve in water and travel through the bloodstream. Are you deficient in the vitamin?
According to the Department of Dermatology at the Hairline International Hair Clinic in India, a B12 deficiency can show up in the hair.
The research team recruited 100 subjects who had their vitamin B12 levels checked.
From the data, the results revealed that people with vitamin B12 deficiency were more prone to premature greying of the hair.
