Saw Palmetto & Hair Loss

Saw palmetto extract is being investigated as a possible treatment for male pattern baldness also known as androgenic alopecia. Some men have reported better hair growth while taking the extract with beta-sitosterol, a phytosterol also present in saw palmetto.  It is believed the action responsible for deterring hair loss and promoting hair growth is the blocking of the enzyme 5-alpha-reductase which aids in the conversion of the hormone testosterone to another hormone dihydrotestosterone. Dihydrotestosterone is considered the key culprit in the onset of male pattern baldness. The theory is present, but there is no conclusive evidence or studies to support saw palmetto hair loss prevention. Products for promoting hair growth containing saw palmetto come in the form of topical oil extract or ointment, or you can take it orally as an herbal medicine.

And males are not alone when it comes to pattern baldness. Women are affected as well and might consider trying to take advantage of the saw palmetto benefits!

    Interestingly enough, saw palmetto has also been considered as treatment for women with hirsutism- it is said to decrease unwanted excess hair.
    Anyone have any idea why it is used for “pattern baldness” as well as treatment for hirsuitsm?
