What is the treatment for gray hair?

Q: My problem is that the hair on the bag containing my testis are going white. I am 23 and worried. I am ashamed of such a strange problem. Please suggest something and help me please.

A:Grey hair is caused by the gradual reduction of melanin production over time within the affected hair follicle. The melanocytes in the hair follicles produce less and less melanin, and the result is a loss of hair fiber colour strength. Grey hair development in the beard and mustache may also start quite early, while grey hair on the chest and pubic region generally only occurs some years after onset of grey hair on the scalp. Apart from colourants, there are no treatments that stop this colour loss. Although some people have used Calcium pantothenate but results haven't been universally encouraging.
