Abstract: 【Abstract】 Androgenetic alopecia (AGA) is mainly characterized by hair follicle miniaturization and hair thinning. Its pathogenesis involves abnormal androgen metabolism, inflammation of the hair follicle microenvironment, and immune imbalance. Studies have shown that excessive activation of the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome and imbalance of the gut microbiota-brain axis are closely associated with the development of AGA. This article reviews the mechanisms of the NLRP3 inflammasome and the gut microbiota-brain axis in the pathological progression of AGA, as well as therapeutic strategies targeting NLRP3-mediated immunomodulation for the treatment of AGA, with the aim of improving therapeutic outcomes.
