الخلاصة

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
