Saw palmetto is well-supported by clinical research as a natural supplement that may help slow hair loss and support regrowth in androgenetic alopecia by naturally inhibiting DHT production.

  • 95% of studies (20/21) show positive effects, including 4 RCTs and 2 meta-analyses
  • Works as a natural 5-alpha reductase inhibitor, reducing DHT levels
  • Both oral supplementation and topical application have demonstrated benefits
  • Generally well-tolerated, though less potent than prescription finasteride
