In sintesi

Spironolactone is well-supported by research as an anti-androgen medication that may help reduce hair loss in androgenetic alopecia, particularly in women, though it requires medical supervision.

76% of studies show positive effects, backed by 4 meta-analyses
Works by blocking androgen hormones that contribute to hair miniaturization
Particularly studied in women with PCOS-related and female pattern hair loss
Requires prescription and medical monitoring due to hormonal effects
