What are potential causes of gray hair in individuals in their 20s, and what factors might contribute to this early graying?

Gray hair in someone in their 20s can be attributed to:

1. Nutrient Deficiencies: For instance, a deficiency in PABA (para-aminobenzoic acid) may contribute.

2. Genetics: Genetic predispositions can play a role.

3. Oxidative Stress: Excess hydrogen peroxide due to inadequate antioxidants.

4. Chronic Stress: Elevated cortisol levels from prolonged stress can significantly impact hair color.

Addressing these factors may help manage or reduce premature graying.
