Recent studies, including work performed by the University of Albany (SUNY) on behalf of HairGenesis (http://www.ncbi.nlm.nih.gov/pubmed/19692448) demonstrates a clear and compelling link between tissue inflammation and pattern hair loss.  Specifically, certain molecular markers of inflammatory cytokines, including CCL17, CXCL6 and LTB(4) are associated with pathways involved in inflammation and apoptosis in many tissue and organ systems, including skin and hair follicles.   Previously, we clinically tested liposterolic extract of Serenoa repens (LSESr) and its glycoside, beta-sitosterol, in subjects likewise affected by pattern hair loss and showed a highly positive response to treatment (http://www.ncbi.nlm.nih.gov/pubmed/12006122).
