People who lack Vitamin B 12 in their bodies often suffer from premature hair loss. If you consume a diet that is inadequate in Vitamin B 12, you experience hair loss, or slow hair growth rate. This is because the body cannot process Vitamin B 12 on its own and cannot utilize the food you eat without vitamin B 12. This results to undernourished hair follicle cells which slows the hair growth rate.
Vitamin B 12 is important for healthy nervous system and the formation of red blood cells and a compromise in either of these can affect our hair.
Vitamin B 12 also stimulates hair growth. Once the level of Vitamin B 12 is corrected, hair follicles start receiving proper nutrients and will be able to replicate correctly which leads to the regrowth of previously lost hair.
Melanin is a form of amino acids known as tyrosine, which helps to support healthy brain functions and is responsible for the pigmentation and colour of hair and skin. Vitamin B12 helps to encourage the re-pigmentation of the hair and also maintains the original colorof the hair.
