As the hair is being formed, melanocytes inject pigment (melanin) into cells containing keratin. Keratin is the protein that makes up our hair, skin, and nails. Throughout the years, melanocyctes continue to inject pigment into the hairâs keratin, giving it a colorful hue. With age comes a reduction of melanin. The hair turns gray and eventually white.
Drinking too much tea, coffee, smoking and alcohol consumption results in grey hair. Reasons of hair graying are excessive intake of tea, coffee and alcohol, of fried and oily foods, spices and sour and acidic foods. Genes play a large role in graying, and there's wide variation among ethnic groups.
