How can i cure the premature hair greying?

you cannot! Older people tend to develop gray hair because the pigment in the hair is lost and the hair becomes colorless. Gray hair is considered to be a characteristic of normal aging. The age at which this occurs varies from person to person, but in general nearly everyone 75 years or older has gray hair, and in general men tend to become gray at younger ages than women. People starting out with very pale blond hair usually develop white hair instead of grey hair when aging. Red hair usually doesn't turn grey as redheads age; red hair usually turns a sandy color and then turns white after that. Some degree of scalp hair loss or thinning generally accompanies in both males and females, and it's estimated that half of all men are affected by male pattern baldness by the time they are 50. The tendency toward baldness is a trait shared by a number of other primate species, and is thought to have evolutionary roots.

you see the pigmentation on your hair is being lost and ther is nothing to do about it. A change in hair color typically occurs naturally as people age, usually turning their hair from its natural color to gray, then to white. More than 40 percent of Americans have some gray hair by their fortieth birthday but grey hairs can appear as early as the teens and twenties for some, or even in childhood. The determination of when someone begins graying, whether it comes with aging or prematurely, seems to be almost entirely based on genetics. Sometimes people are born with gray hair through inheritance because it is passed down genetically.

The change in hair color is caused by the gradual decrease of pigmentation that occurs when melanin ceases to be produced in the hair root, and new hairs grow in without pigment. Two genes appear to be responsible for the process of greying, Bcl2 and Mitf. The stem cells at the base of hair follicles are responsible for producing melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes hair to begin going grey. (Nishimura, et al., 2005)

There are no special diets, nutritional supplements, vitamins, nor proteins that have been proven to slow, stop, or in any way affect the graying process, although many have been marketed over the years.

Many people use hair dye to disguise the amount of gray in their hair.

A 1996 British Medical Journal study conducted by J.G. Mosley, MD found that tobacco smoking may cause premature graying. Smokers were found to be four times more likely to begin graying prematurely, compared to nonsmokers in the study.
