What is saw palmetto?
Saw palmetto is a type of small palm tree native to the southeastern United States. It produces a berry that, when ripe, has been used for centuries in traditional medicine, primarily for urinary and reproductive issues. In recent years, it has also gained popularity as a potential treatment for hair loss.
The berries of this plant contain various bioactive compounds, including fatty acids and sterols.
It's thought that these components have anti-androgenic effects, meaning they can block the activity of androgens, like dihydrotestosterone (DHT), which is a key player in androgenetic alopecia.
As a natural supplement, saw palmetto is commonly used in various forms such as capsules, tablets, and liquid extracts.
How does saw palmetto help with hair regrowth?
Saw palmetto is believed to promote hair regrowth by inhibiting the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). High levels of DHT are associated with hair loss in people with androgenetic alopecia, as it shrinks hair follicles and shortens the hair growth cycle.
By reducing DHT levels, saw palmetto may help slow hair loss and potentially stimulate new growth, and this has been demonstrated according to research as well.
What are the benefits of saw palmetto?
Saw palmetto offers numerous health benefits, thanks to its rich content of bioactive compounds. Beyond its potential use in hair loss treatment, it's commonly used to alleviate urinary symptoms and improve prostate health.
Here are several key benefits associated with saw palmetto:
- Balancing hormone levels: Some evidence suggests that saw palmetto may help balance hormone levels in the body, potentially benefiting those with conditions like polycystic ovary syndrome (PCOS) that are associated with hormonal imbalances.
- Hair loss treatment: As we've discussed, saw palmetto may inhibit the conversion of testosterone into DHT, a hormone associated with androgenetic alopecia. By blocking this process, saw palmetto could potentially slow hair loss and stimulate hair regrowth.
- Anti-inflammatory properties: Saw palmetto has been observed to possess anti-inflammatory properties, which might aid in managing various inflammatory conditions.
- Skin health: Its potential anti-inflammatory and hormonal balancing effects could potentially improve certain skin conditions, such as acne.
- Supports immune system: Saw palmetto may have immune-supporting properties, possibly due to its rich antioxidant content.
What are the side effects of saw palmetto?
While saw palmetto is generally considered safe for most people when taken in recommended doses, it can cause side effects in some individuals. These can range from mild to severe, and it's important to consult a healthcare provider before starting any new supplement regimen.
Here are some potential side effects associated with saw palmetto:
- Gastrointestinal issues: Some people may experience digestive upset, including nausea, vomiting, diarrhea, or constipation.
- Headaches and dizziness: Saw palmetto can cause headaches or dizziness in some individuals, especially when starting the supplement.
- Fatigue: Some people may feel unusually tired or fatigued when taking saw palmetto.
- Sexual side effects: Although rare, saw palmetto has been associated with decreased sexual drive or difficulty achieving an erection. This is due to its impact on hormonal balance.

What is finasteride?
Finasteride is a prescription medication that is primarily used to treat male pattern baldness (androgenetic alopecia) and benign prostatic hyperplasia (BPH). It works by inhibiting the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone that plays a key role in hair loss and prostate growth.
How does finasteride help with hair regrowth?
Finasteride helps with hair regrowth by blocking the action of 5-alpha reductase, an enzyme that converts testosterone into dihydrotestosterone (DHT). DHT is a hormone that can shrink hair follicles and shorten the hair growth cycle, leading to hair loss in individuals with androgenetic alopecia.
By reducing the levels of DHT in the scalp, finasteride slows the hair loss process and can stimulate new hair growth in the existing follicles.
What are the benefits of finasteride?
Finasteride is a well-researched medication known for its efficacy in treating two main conditions: androgenetic alopecia, or male pattern baldness, and benign prostatic hyperplasia (BPH). It offers a variety of benefits in managing these conditions.
Here are the key benefits associated with finasteride:
- Hair Loss treatment: One of the primary benefits of finasteride is its ability to slow down the progression of male pattern baldness and stimulate hair regrowth. Numerous studies have demonstrated its effectiveness in these areas.
- Prostate health: Finasteride is also used to treat benign prostatic hyperplasia (BPH), a condition characterized by an enlarged prostate that can cause urinary issues. It can help reduce the size of the prostate gland and alleviate symptoms.
- Long-Term safety and efficacy: Finasteride has been in use for several decades, with numerous studies supporting its long-term safety and efficacy when used as directed.
- Convenience: Finasteride is taken orally, usually as a daily tablet, which makes it a convenient treatment option.
What are the side effects of finasteride?
Here are some possible side effects associated with finasteride:
- Sexual side effects: Finasteride may cause a decrease in sexual desire, difficulty in achieving an erection, and a decrease in the amount of semen released during sex. These side effects occur in a small percentage of patients and often resolve after discontinuing the medication or over time with continued use.
- Breast changes: Some men have reported changes in the breasts, including enlargement or tenderness, and in rare cases, male breast cancer.
- Depression and anxiety: Some individuals have reported mood changes, including depression and anxiety, while taking finasteride.
- Allergic reactions: Though rare, some people may experience an allergic reaction to finasteride, which could include symptoms like rash, itching, hives, and swelling of the lips or face.
- Potential impact on prostate cancer screening: Finasteride can affect the levels of prostate-specific antigen (PSA), a marker used in screening for prostate cancer, which could complicate the interpretation of these tests.

Saw palmetto vs finasteride: Which one is right for you?
Choosing between saw palmetto and finasteride for hair loss depends on your preferences, the severity of your hair loss, and your tolerance for potential side effects.
Saw palmetto, a natural supplement, is suitable for mild to moderate hair loss and is generally well-tolerated with fewer side effects, as it works by inhibiting DHT production.
On the other hand, finasteride is clinically proven to be more effective for significant hair loss, offering better results in hair regrowth and scalp coverage.
However, as Dan Gallagher notes, "finasteride tends to cause more hormonal side effects, leading to changes in mood, libido, and body composition," making saw palmetto a preferable option for many.
Additionally, finasteride is not recommended for women due to its potential side effects.
Conclusion
Managing hair loss requires careful consideration of treatment options. Both saw palmetto and finasteride are effective, each with unique benefits and potential side effects. Saw palmetto offers a natural, gentler approach, while finasteride provides a potent, clinically proven solution.
You might also explore alternatives like Bio-Pilixin Serum, which supports hair vitality and comes with a money-back guarantee. Ultimately, your choice should align with your needs, preferences, health, and guidance from your healthcare provider.
