As a subject matter expert in biology and physiology, I can tell you that the color of your hair is determined by the presence of a pigment called melanin, which is produced by cells called melanocytes. The reduction or absence of melanin production as you age is the primary cause of white hair. This can be due to several factors:
1. Genetics: The most common reason for hair turning white is aging, which is largely a genetic process.
2. Oxidative Stress: Over time, oxidative stress can damage melanocytes, leading to a decline in melanin production.
3. Vitamin Deficiency: A deficiency in certain vitamins, particularly vitamin B12, can contribute to the graying process. This vitamin is essential for the production of red blood cells and maintaining a healthy nervous system, and it plays a role in maintaining hair color.
4. Mineral Deficiency: Lack of certain minerals like copper, iron, and zinc can also affect melanin production.
5. Autoimmune Conditions: Sometimes, autoimmune diseases can attack the melanocytes, causing hair to turn white.
6. Environmental Factors: Exposure to environmental pollutants or UV radiation can also lead to oxidative stress and damage to melanocytes.
It's important to note that while a deficiency in certain nutrients can contribute to the graying process, it is not the sole cause, and hair color is a complex trait influenced by multiple factors.

It could be related to vitamin D because in certain vitamin D resistant syndromes hair growth stops or it is thin and often gray. Graying hair in young women is often associated with osteopenia (bone thinning) and/or thyroid problems. Vitamin B-12 deficiency, anemia or viruses can cause gray hair to appear as well.
