Many herbal practitioners prescribe saw palmetto as a cure for hair loss. Saw palmetto is a powerful DHT reducer and has been shown in clinical trials to be effective for those suffering from an enlarged prostate. There have not been many trials done on saw palmetto for hair loss however. Small trials seem to show that it is as effective as Propecia. Saw palmetto may be a safer alternative than Propecia to slow or prevent hair loss. For more about the effect of saw palmetto on alopecia see: Saw Palmetto and Hair Loss
