Question

Why does hair discolorate as you get older?

Answer 1

d'more chemicals that are used in your hair during your lifetime, the quicker your hair will grow grey. Hair color is the result of pigmentation due to the presence of the chemicals of melanin. In general, the more melanin, the darker the hair color.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.

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. This may change in the near future as French scientists treating cancer patients for a new drug found that some of the patients' hair color from before they turned grey had been restored.

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.
