Gray hair in your 30s is normal aging

The appearance of gray hair in one's 30s is a normal sign of aging, according to a dermatology professor, and is common for people of various ethnicities. Hair turns gray as melanin-producing cells lose their ability to color hair, and this process typically begins in the 30s or 40s. Factors like excessive alcohol consumption, smoking, genetics, and certain health conditions can accelerate the process. While some nutritional deficiencies can cause graying, reversing the process is difficult, though not impossible. Research suggests that taking vitamins and minerals to treat gray hair has not been proven effective.
