10.Premature Gray Hair Is Genetic
Going gray isn’t always related to aging. If you’re not yet 40 and see more than a few gray hairs, chances are it runs in your family. Gray usually isn’t a sign of poor health, though anemia, thyroid issues, vitamin B12 deficiency, and vitiligo can cause premature graying. You can highlight or color hair to cover the gray, but beware: Some people are sensitive to the chemicals in dyes. The result could be an itchy, burning scalp.
