what foods prevent grey hair
4. Lentils. Lentils are full of vitamin B-9, also known as folic acid. Like B-12, a deficiency in vitamin B- 9 can lead to prematurely grey hair because it is an important component of methionine. Methionine, an amino acid, blocks natural damage to the hair cells that can lead to a loss of hair color.
1. Eggs. Pernicious anemia is a deficiency in vitamin B-12 that can cause hair to prematurely lose its color. This happens because your body cannot produce enough melanin, which is the pigment that gives you hair its color. Luckily, eggs are full of B vitamins, including high levels of B-12.
