May 2023 in “GLOBAL JOURNAL FOR RESEARCH ANALYSIS” This study found that males with early onset androgenetic alopecia had significantly lower serum vitamin D levels compared to age-matched healthy controls, although no correlation between the severity of alopecia and vitamin D levels was observed.
April 2022 in “JAAD International” This study suggests that vitamin D deficiency is likely not involved in the development of frontal fibrosing alopecia, as patients showed similar vitamin D levels to those with female pattern hair loss.
January 2021 in “Case Reports” This case study reports a rare instance of mucinous cystadenoma causing severe virilization in a postmenopausal woman, highlighting a possible link with rapidly progressive hyperandrogenism.

May 2017 in “Endocrine Abstracts” This study found that men with early-onset androgenetic alopecia who also met criteria for the male PCOS-equivalent may have impaired gonadal steroidogenesis, suggesting increased risk of future gonadal dysfunction.
58 citations
,
January 2006 in “Skin Pharmacology and Physiology” This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.
