Saw Palmetto for Hair Loss: Fact or Fiction?

Saw Palmetto for Hair Loss: Fact or Fiction?

Hair loss is a common concern for both men and women, often leading to a search for effective remedies. One such natural remedy that has gained popularity in recent years is saw palmetto. Derived from the fruit of the Serenoa repens palm tree, saw palmetto is known for its potential benefits in addressing hair loss. In this blog article, we will explore the effectiveness of saw palmetto for hair loss, examining the available evidence and shedding light on its potential benefits.

Understanding Hair Loss:

Before delving into the topic, it's important to understand the underlying causes of hair loss. The most common form of hair loss, known as androgenetic alopecia, is primarily caused by a hormone called dihydrotestosterone (DHT). DHT binds to hair follicles, causing them to shrink and eventually leading to hair thinning and loss.

Saw Palmetto and DHT:

Saw palmetto is believed to work by inhibiting the conversion of testosterone into DHT. It contains compounds that may block the enzyme 5-alpha-reductase, which is responsible for this conversion. By reducing DHT levels, it is thought that saw palmetto may help slow down the progression of hair loss and promote hair regrowth.

Research on Saw Palmetto and Hair Loss:

While saw palmetto has been traditionally used for various purposes, including hair loss, the scientific evidence supporting its effectiveness is limited and inconclusive. Many studies conducted on the topic have produced conflicting results, making it challenging to draw definitive conclusions.

One study published in the Journal of Alternative and Complementary Medicine in 2002 found that saw palmetto improved hair growth in men with mild to moderate androgenetic alopecia. However, this study had a relatively small sample size, and more research is needed to confirm these findings.

Another study published in the Journal of Cutaneous and Aesthetic Surgery in 2014 reviewed existing literature on saw palmetto and concluded that it may have potential as a treatment option for hair loss. However, the authors noted that more rigorous clinical trials are necessary to establish its efficacy.

It's worth mentioning that the U.S. Food and Drug Administration (FDA) has not approved saw palmetto as a treatment for hair loss. Additionally, the American Academy of Dermatology does not recommend it as a first-line treatment option due to the lack of conclusive evidence.

Considerations and Precautions:

While saw palmetto is generally considered safe for most people, it may cause side effects in some individuals. These can include stomach discomfort, headaches, and dizziness. If you are considering using saw palmetto for hair loss, it is advisable to consult with a healthcare professional, especially if you have any pre-existing medical conditions or are taking other medications.


Saw palmetto has gained attention as a potential natural remedy for hair loss, primarily due to its ability to inhibit the conversion of testosterone into DHT. However, the scientific evidence supporting its effectiveness remains inconclusive. While some studies suggest potential benefits, more extensive and rigorous research is needed to establish saw palmetto as a reliable treatment option. In the meantime, it is important to approach saw palmetto with caution and consult with a healthcare professional before incorporating it into your hair loss regimen.
