Green tea extract has very limited evidence for androgenetic alopecia — while early findings are positive, the research is too preliminary to draw meaningful conclusions.

                    Only 3 studies exist, with no randomized controlled trials

                    EGCG in green tea may have anti-androgenic properties relevant to pattern hair loss

                    The single interventional study used a multi-ingredient serum, not green tea extract alone

                    Much more research is needed before green tea extract can be recommended for hair loss
