TLDR Premature greying of hair in young adults is linked to genetics, lifestyle, and nutrient deficiencies.
A study involving 520 dermatology out-patients found that nearly 25% of young adults had premature greying of hair (PGH), defined as having ≥5 grey hairs before age 25 in Asians. The study identified genetic predisposition, modifiable lifestyle factors, and correctable micronutrient deficiencies as independent risk factors for PGH. It suggests that early behavioral and nutritional interventions in student-health clinics could help reduce the psychosocial burden associated with PGH.
