TLDR Most young men with early gray hair have low vitamin D but normal iron levels.
The study conducted with 100 male participants under 25 years old at the Universitas Sumatera Utara area found that 77% had decreased vitamin D levels and 91% had normal serum ferritin levels, with no significant correlation between the number of gray hairs and the levels of these nutrients. The research concluded that young adult males with premature hair graying (PHG) generally had low vitamin D levels but normal serum ferritin levels, and recommended further research with a larger sample size and inclusion of female subjects.
