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.
Gray hair is a sign of age, not wisdom.. Having gray hair is a common occurrence to almost everyone especially at the adulthood stage. Hair has a tendency to lose its natural colour with advancing age and turn grey, but premature greying is a morbid condition and it makes even the young look older. Graying of hair may occur to some people who have medical conditions, but this should not worry you if you do not have any illness.
