    TLDR Low vitamin D levels are linked to increased risk of male pattern baldness.
    In a case-control study with 100 male participants from eastern Uttar Pradesh, India, researchers discovered a significant link between vitamin D deficiency and androgenetic alopecia (AGA). The study compared 50 AGA patients with 50 age-matched controls and found that 56% of the AGA group had vitamin D levels below 20 ng/ml, compared to 24% in the control group, indicating a fourfold increased risk of AGA associated with low vitamin D levels. The average serum vitamin D level was significantly lower in the AGA group (33.1±10.6 ng/ml) than in the control group (40.3±9.51 ng/ml). The study suggests that vitamin D might be involved in the development of AGA and recommends monitoring vitamin D levels in AGA patients, although it calls for further research to confirm these findings and to assess the potential of vitamin D supplementation as a treatment option.
