Premature graying may be because of numerous reasons.
When melanin production reduces in the hair root, new hair grows without pigment.
If your ancestors had gray hair at an early age, it is likely that you will, too.
Hair has protein, and its deficiency may lead to loss of hair pigment.
If the immune system attacks its own body cells instead of invader cells, it leads to gray hair.
Hair might turn gray if there’s an imbalance between oxygen-containing molecules and antioxidants in your body.
Stress, anxiety, and worries for prolonged periods deplete stem cells in hair follicles and result in premature graying.
Not including essential nutrients and frequently eating fast food may block hair follicles.
