The saw palmetto tree (Serenoa repens) is a native plant found across the southern regions of the United States, spanning from Florida to California. Its distinctive fan-like leaves sway in the wind, and its trunks can reach heights of up to ten feet. For centuries, humans have utilized this hardy palm for a variety of purposes, including crafting baskets, producing oils and waxes, and even as a medicinal ingredient. But can saw palmetto actually help in preventing hair loss?
Today, saw palmetto remains a widely used herbal supplement, available in both topical and oral forms. Approximately 2 million men take saw palmetto for various reasons, ranging from prostate health support to treating androgenetic alopecia (hair loss). In this article, we’ll explore its potential benefits, safety profile, and effectiveness in preventing hair thinning and baldness.
The Benefits of Saw Palmetto
Saw palmetto has been traditionally used around the world for various health concerns, including:
- Prostate function support
- Urinary system health
- Anti-inflammatory properties
- Regulating testosterone levels
- Managing androgenetic alopecia
One of the most well-known applications of saw palmetto is in managing prostate health. It is commonly used to help with benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland. As men age, BPH becomes increasingly common and can lead to uncomfortable urinary issues, including difficulty urinating and an increased risk of bladder and kidney complications.
Interestingly, the same biological mechanism that makes saw palmetto potentially beneficial for prostate health may also contribute to its effectiveness in addressing hair loss. The enlargement of the prostate is linked to an enzyme called 5-alpha reductase (5-AR), which converts testosterone into dihydrotestosterone (DHT). This same hormone, DHT, is also responsible for triggering androgenetic alopecia, or male pattern baldness. By inhibiting this process, saw palmetto could play a role in reducing hair loss.
How Does Saw Palmetto Help with Hair Loss?
Androgenetic alopecia is primarily caused by excessive DHT levels. This hormone binds to hair follicle receptors, causing them to shrink over time, leading to hair thinning and eventual hair loss. Saw palmetto is believed to counteract this process by inhibiting the production of DHT and reducing its impact on hair follicles.
By preventing the enzyme 5α-reductase from converting testosterone into DHT, saw palmetto may slow down the accumulation of DHT and limit its ability to bind to receptors in hair follicles. This is the same mechanism behind Finasteride, an FDA-approved medication known to reduce hair loss. While scientific research on saw palmetto’s role in hair growth is still emerging, early studies and anecdotal reports suggest that it may slow the progression of baldness in a similar way.
Does Saw Palmetto Really Work?
Scientific evidence on saw palmetto’s effects on hair loss is still limited, but the available studies are encouraging. Some research suggests that saw palmetto, when used either orally or topically, can increase hair count by up to 27% and improve hair density in approximately 83% of individuals with pattern hair loss.
However, most of the existing research is either small-scale or anecdotal. While preliminary findings suggest that saw palmetto has potential as a hair loss treatment, larger, more comprehensive clinical trials are necessary to confirm its efficacy.
It is also important to note that while saw palmetto may help inhibit DHT, the only widely recognized and scientifically validated treatment for reducing DHT levels remains Finasteride. This drug is clinically proven to improve prostate health and has received FDA approval for treating hair loss in men.
Can Women Use Saw Palmetto?
Most studies on saw palmetto have focused on its effects on men, meaning there is limited data on its safety and effectiveness in women. However, it is generally considered safe for women to use unless they are pregnant or breastfeeding.
Women who are considering taking saw palmetto should consult with a healthcare professional, particularly if they are taking medications or managing chronic health conditions.
Is Saw Palmetto Safe?
For most individuals, saw palmetto is considered safe, with minimal risk of serious side effects. However, some people may experience mild side effects such as:
- Digestive discomfort (diarrhea, nausea, vomiting)
- Headaches
- Fatigue
- Decreased libido
- Dizziness or vertigo
Pregnant and breastfeeding women should avoid using saw palmetto, and anyone considering this supplement should consult a medical professional before starting a new regimen.
Where Can You Find Saw Palmetto?
Saw palmetto is widely available in both oral and topical forms. Supplements typically come in capsule or tablet form, while topical products often include saw palmetto oil as an ingredient.
Some shampoos and hair growth formulations, include saw palmetto alongside other natural DHT blockers like pumpkin seed extract and rosemary. These topical applications tend to be milder in effect compared to oral supplements. While such products are generally considered safe, it is always advisable to check with a healthcare provider before use—especially during pregnancy or breastfeeding.
How Much Saw Palmetto Should You Take?
The Healthy Hair Growth Supplement for Men generally includes 160 mg of saw palmetto berry extract per capsule, a dosage believed to be effective in men. However, the Healthy Hair Growth Supplement for Women does not contain saw palmetto, as there is still insufficient scientific evidence on its safety and effectiveness for women.
Final Thoughts
Current research suggests that saw palmetto extract may have the potential to slow hair loss by inhibiting DHT, the hormone linked to pattern baldness. Many individuals who use saw palmetto in their hair care routines report positive results, and the supplement is frequently discussed in online reviews and forums.
That said, because more effective treatments exist—such as Finasteride and Minoxidil—saw palmetto may be best used as a complementary treatment rather than a standalone solution.
Dealing with hair loss can be challenging, but there are multiple solutions available, including oral medications, topical treatments, supplements, and even hair restoration procedures. The key is to find the right combination that works for you.
