"Hair color is the result of pigmentation due to the chemicals eumelanin and phaeomelanin. In general, the more melanin present, the darker the hair color; the less melanin, the lighter the hair color. Considerable differences in color and texture exist between individuals of similar ethnicity, and immigration and global travel have greatly increased the diversity of hair characteristics among many countries. A person's hair color may also change over time and may be more than one color at a time.
Grey hair color typically occurs naturally as people age. (See Effects of aging on hair color, below.) In some cases, grey hair may instead be caused by a deficiency of B12 or a thyroid imbalance.
A change in hair color typically occurs naturally as people age, usually turning their hair to gray and then white. More than 40 percent of people have some gray hair by age 40, but white hairs can appear as early as childhood. The age at which graying begins seems to be almost entirely based on genetics. Sometimes people are born with gray hair because they inherit the trait genetically."
Research on white hair problem in early ages (all over the globe ) is being done by Dr R.V R Murthy , Srikakulam, A.P INDIA
