Nothing to worry about,it's genetic. The gene that controls the production of melanin which is responsible for putting the color into your hair and skin, has told some of your whiskers to stop producing it and causes the hair to become white or actually clear and colorless. When this happens is all in your DNA. Most of us will eventually lose most of the color producing melanin in our hair. But there are people whom still maintain the natural color of their hair well into their 70's and children as young as 4 or 5 that get a patch of "gray" but for most of us this begins around 20 with facial hair and or hair on our heads and just gradually becomes more noticeable as we age. You will be glad to know though that in most people pubic hair, legs, and arms are the last to lose melanin.
