Biotechnologists Say that naturally Grey Haired Persons have a greater protection shield against cancer. The Japanese researchers conducted experiments on the mice and concluded that the grey haired persons have tender protection against cancer. Researches say that melanocytes are the cells which are involved in production of pigments that color hair.
Their numbers are kept topped up by stem cells. The hair goes grey when these number of stem cells in hair follicles declines and this paves for protection against cancer.
To explain this more clearly and scientifically, the Biotechnologists exposed mice to radiation and chemicals which will harm DNA. After exposure the damaged stem cells started transforming into melanocytes permanently.
The researchers further revealed that the mice went gray during this experiment. The Biotechnologists believe that the same process made lesser stem cells in the follicles of older people. This occurs when DNA damage accumulates as they age. This clearly proves that for grey haired people the dead stem cells converts into melantocytes as they showed in rats. This paves to be a better way for providing a shield against cancer. Remember that one should have the Grey hair naturally. Obtaining Grey hair through artificial method wont protect you against cancer.
