3. Nutritional supplements
Sometimes our gray hair tells us that our body needs more nutrients and that we need to resort to nutritional supplements. According to a study of 52 people, low levels of vitamins B12, B7 (biotin), B9 (folate), and D3 were found in people who experienced premature whitening. Supplementing these nutrients may help keep your hair looking younger and healthier for longer.
4. Foods rich in catalase
Sweet potatoes, carrots, red peppers, and mushrooms are just a few foods that can help prevent premature graying. This is because they contain high levels of an enzyme called catalase, which protects your hair pigment. Eating these foods regularly may help prevent premature graying of your hair.
