Explores the use of saw palmetto for treating hair loss, mentioning its application, potential side effects, and potential alternative treatments.
Saw palmetto, a small palm tree native to the West Indies, has been gaining attention as a potential treatment for hair loss. While the scientific consensus is not yet fully conclusive, some promising clinical trial data suggest that saw palmetto could help reduce hair shedding and improve hair density.
In a significant double-blinded, placebo-controlled clinical trial involving 80 men and women suffering from mild-to-moderate androgenetic alopecia, taking a standardized oral saw palmetto oil (100 mg daily) for 16 weeks led to an 11.3% increase in hair density, a 34% reduction in hair shedding, a 16.6% decrease in hair loss, and an 18.9% reduction in blood DHT (dihydrotestosterone) levels, a hormone linked to hair loss [1].
Saw palmetto is considered a natural DHT blocker, and since DHT plays a key role in androgenetic alopecia (pattern hair loss), reducing DHT could potentially help slow or reverse hair loss. However, reviews note that results from clinical studies on natural DHT inhibitors like saw palmetto remain mixed, and further robust research is needed to confirm long-term efficacy and safety [2][3].
Some sources suggest that saw palmetto could be combined with other agents like wheat ceramides for enhanced effects in female hair loss cases [1]. Saw palmetto may work by inhibiting 5-alpha reductase, the enzyme that converts testosterone to DHT, thus lowering DHT levels and potentially reducing hair follicle miniaturization [2].
However, it's important to note that the effectiveness of saw palmetto for hair loss may be less for those with more severe hair loss. There is not enough scientific evidence to confirm that saw palmetto is effective for any health condition, including hair loss.
Research has not shown that saw palmetto interacts with any medications, but it is advisable to consult a doctor before taking it. Saw palmetto is available in oral supplements and hair care products like shampoos and conditioners, but there is no official recommended dosage.
In addition to saw palmetto, other lifestyle changes may help promote hair growth and improve its strength and volume. Eating eggs, Brazil nuts, and fatty fish can help, as they contain nutrients essential for hair growth. Doctors may also recommend using gentle hair care products, avoiding heat styling tools, limiting hair dryer use, avoiding tight hairstyles, brushing the hair gently, and avoiding hairstyles that pull the hair back tightly.
While saw palmetto shows promise, more large, well-designed, and longer-term studies are needed to establish conclusive evidence for its effectiveness in hair loss treatment. Until then, it remains a potentially beneficial natural option but is not yet a definitive or universally recommended therapy for hair loss.

Careful consideration should be taken when using saw palmetto supplements for hair loss, as the effectiveness may vary for individuals with more severe cases. For optimal results, the supplement could be combined with other agents, like wheat ceramides, particularly in female hair loss cases [1].
The potential benefits of saw palmetto extend beyond hair loss treatment, as it works by inhibiting the 5-alpha reductase enzyme, which in turn lowers DHT levels, a key factor in pattern hair loss [2].
Incorporating a balanced diet rich in nutrients essential for hair growth, such as eggs, Brazil nuts, and fatty fish, can complement the use of saw palmetto supplements [3].
To further promote hair health, consider using gentle hair care products, avoiding heat styling tools, and adopting a gentle brushing routine. Opt for hairstyles that do not pull the hair back tightly, and limit the use of hair dryers [3].
