Supplementary Material For: The Role Of Fibrosis In Androgenetic Alopecia: Mechanisms And Implications

This review discusses the role of perifollicular fibrosis in androgenetic alopecia and explores potential anti-fibrotic therapies targeting specific signaling pathways, but it reports no new clinical results.

This review discusses the role of perifollicular fibrosis in androgenetic alopecia and suggests that targeting specific signaling pathways could improve treatment outcomes, but reports no new clinical results.

This document supplements a study on androgenetic alopecia, describing materials and methods, and includes figures showing fibrosis in the bulge region of miniaturized hair follicles.

This narrative review highlights current insights into how perifollicular fibrosis contributes to androgenetic alopecia, by hindering hair regrowth and treatment response, and outlines potential antifibrotic therapies, though conclusive evidence from randomized controlled trials is still needed.

This research suggests that testosterone-induced expression of TGF-beta1 and type I procollagen may lead to perifollicular fibrosis in androgenetic alopecia, with finasteride inhibiting this process as a possible mechanism for its effects.
