Magnitude and Contributing Factors Responsible for Premature Greying of Hair: A Cross-Sectional Study

This cross-sectional study investigated the prevalence and contributing factors of premature greying of hair (PGH) among 520 dermatology out-patients in an academic medical setting in India. PGH was defined as having 5 or more grey hairs before age 25 in Asians. The study found that nearly 25% of young adults had PGH, with genetic predisposition, modifiable lifestyle factors, and correctable micronutrient deficiencies being significant risk factors. The authors suggest that early behavioral and nutritional interventions in student-health clinics could help reduce the psychosocial impact of PGH.
