Saw palmetto extract comes from berries of the palm tree Saw palmetto (Serenoa repens) which is indigenous to the Atlantic Southeast coast of North America. Studies have shown that Saw palmetto is an effective anti-androgen. It acts in a similar way that Propecia does. Firstly it lowers levels of DHT in the body by blocking 5 alpha-reductase. Secondly Saw Palmetto blocks receptor sites on cell membranes required for cells to absorb DHT. Although no studies have been carried out on Saw palmetto and its relation to hair growth. Studies have been performed on the use of Saw palmetto in the treatment of benign prostatic disease which similar to Androgenetic Alopecia also depends on the production of dihydrotestosterone(DHT). All of the studies that have been performed to date show that Saw palmetto is an effective anti-androgen and has shown conclusively to be effective in the treatment of benign prostate disease. One may assume from this that since Saw palmetto is an effective anti-androgen and is used in the treatment of prostatic disease then it may also be effective in the treatment of Androgenetic alopecia. More and more people around the globe are starting to use Saw palmetto in the treatment of benign prostatic hyperplasma and in the treatment of Androgenetic alopecia.
Saw Palmetto may prevent the binding of dihydrotestosterone (DHT) to androgen receptors and, therefore, may also be of use to prevent hair loss and other undesirable effects of DHT.
