Understanding the Role of B12 in Hair Health
B12 deficiency can cause hair issues like shedding, thinning, and early graying. This happens because B12 is important in the hair growth cycle and for hair follicles.
Research on Telogen Effluvium and B12 Levels
Telogen effluvium is a condition with too much hair shedding, often due to stress, poor nutrition, or hormonal changes. Studies show people with telogen effluvium often have low B12 levels. This suggests a link between B12 deficiency and this condition.
