    TLDR Low vitamin D3 levels are significantly linked to hair loss, especially in female students.
    The document is a review of a case-control study conducted by Nayak et al. in 2016, which investigated the relationship between serum vitamin D3 levels and diffuse hair fall among students in South India. The reviewers noted that the study found a significant difference in participants attributing dietary factors to hair fall. However, they questioned whether the study collected details about the participants' diets, which could affect vitamin D levels. The reviewers also pointed out that the study did not account for the time of day of sunlight exposure, which could influence vitamin D synthesis. Despite these limitations, the study found that only one participant had normal vitamin D3 levels, reaffirming the global issue of hypovitaminosis D. The reviewers concluded that vitamin D supplementation might become a common prescription for patients with diffuse hair fall in the future.

      A 33-year-old male experienced sudden, rapid hair loss, possibly due to a reaction to mentholated shampoo and undiluted tea tree oil, with a history of seborrheic dermatitis. He is currently taking finasteride, vitamin D3, a multivitamin, and biotin, and is seeking further medical evaluation.
