Why White Hair Before 20? 7 Reasons Young People Are Graying Prematurely

• Genetics: Family history is a strong, unchangeable factor for premature graying, as noted by Dr. Shraddhey Katiyar.
• Nutritional Deficiencies: Lack of Vitamin B12, iron, copper, and zinc directly impacts melanin production.
• Stress & Sleep: Prolonged mental stress destroys melanocyte stem cells; irregular sleep disrupts protective melatonin.
• Poor Diet: Sugary, processed foods, and refined oils lack micronutrients, affecting hair health first.
• Thyroid & Lifestyle: Both thyroid conditions, smoking, vaping, and autoimmune diseases accelerate graying.

Why It Matters: Genetics, diet, stress, and lifestyle are key factors behind premature graying in youth.
