Your Hair is Going Gray before 40
Silver, pewter, charcoal, salt and pepper – whatever color of the spectrum you end up on, gray hair happens to everyone at some point. This happens when color producing cells in your hair follicles stop producing pigment.
Going gray generally does not mean that you have a medical condition, except in rare cases. When you go gray will depends on genetic factors, but for some people, premature graying can be linked to other health problems. A vitamin B-12 deficiency or problems with your pituitary or thyroid gland can cause hair to turn gray. If this is the case, graying can be reversed when the problem is addressed.
