July 2022 in “British Journal of Dermatology” December 2022 in “PubMed” This study observed that one-third of men with early-onset androgenetic alopecia had altered hormonal profiles, which were associated with increased insulin resistance and more severe hair loss.
December 2023 in “International Journal of Research in Dermatology” This study evaluated hormonal differences in males with early androgenetic alopecia, finding increased serum testosterone, prolactin, LH, LH/FSH, and FAI levels, with decreased FSH and SHBG levels, compared to controls without hair loss.
September 2024 in “Journal of the American Academy of Dermatology” In this prospective study, researchers observed that early-onset androgenetic alopecia may predispose young male patients to metabolic syndrome, as significant differences in metabolic profiles were found between these patients and age-matched controls.
May 2024 in “Journal of cosmetic dermatology” This study found that early-onset male androgenetic alopecia is associated with abnormal lipid metabolism and lower levels of certain serum markers, which may serve as risk factors or protective factors for the condition.
