What is Saw Palmetto?
Saw palmetto (Serenoa repens) is a small palm native to North America. Its berries are widely used in dietary supplements, usually in capsule, tablet, or oil form. Research shows that saw palmetto contains fatty acids and phytosterols, which act as a natural DHT (dihydrotestosterone) blocker.
Since DHT is the hormone responsible for male pattern baldness and prostate enlargement (benign prostatic hyperplasia or BPH), saw palmetto has become popular as a natural aid for men’s health.
How Saw Palmetto Works
Blocks DHT Naturally
DHT shrinks hair follicles, leading to thinning hair and eventual baldness. Saw palmetto may reduce DHT activity, slowing down this process.Supports Prostate Health
In men over 40, an enlarged prostate can cause frequent urination. Studies suggest saw palmetto helps reduce urinary symptoms linked to BPH.Anti-Inflammatory Properties
The phytosterols in saw palmetto have anti-inflammatory effects, beneficial for both scalp health and urinary function.
Main Uses of Saw Palmetto
1. Saw Palmetto for Hair Loss
Helps men with androgenetic alopecia (male pattern baldness).
Some women with hormonal thinning hair may also see improvement.
Works best when combined with treatments like minoxidil, PRP therapy, or hair transplant surgery.
2. Saw Palmetto for Prostate Health
Traditionally used to ease urinary difficulties caused by BPH.
Clinical trials show it may improve urine flow and reduce discomfort, though results vary.
3. Hormonal Balance & Wellness
Supports testosterone balance in men.
May promote sexual health and overall vitality.
Forms of Saw Palmetto Supplements
Capsules / Tablets – the most common and convenient option.
Softgel Oil Extracts – concentrated form with higher potency.
Powder or Tincture – used in traditional herbal medicine.

Saw Palmetto vs Finasteride vs Dutasteride – Which One Is More Effective to Block DHT?
When it comes to treating hair loss caused by DHT (dihydrotestosterone), different options exist — from natural extracts to prescription medications such as finasteride and dutasteride. Understanding how they compare can help you choose the right treatment.
Saw Palmetto
A natural supplement derived from the berries of the Serenoa repens plant. Research suggests it may help reduce DHT levels by inhibiting the enzyme 5-alpha reductase, though its effects are generally milder compared to prescription drugs. It is often preferred by individuals looking for a natural approach or those sensitive to medications.Finasteride
A widely prescribed oral medication for male pattern baldness. It selectively inhibits Type II 5-alpha reductase, significantly lowering scalp and serum DHT levels. Clinical studies show finasteride can slow hair loss and promote regrowth in many men.Dutasteride
A more potent prescription option. Unlike finasteride, dutasteride blocks both Type I and Type II 5-alpha reductase enzymes, leading to greater suppression of DHT. Studies indicate it may be more effective than finasteride, but it may also carry a higher risk of side effects.
Verdict:
Most potent DHT blocker → Dutasteride
Clinically proven and widely used → Finasteride
Natural alternative with milder effects → Saw Palmetto
Conclusion
Saw palmetto is one of the most popular natural supplements for men’s health. With potential as a DHT blocker, it offers dual benefits: supporting hair preservation and prostate wellness. While its effects may be slower and less predictable compared to prescription drugs, saw palmetto remains an attractive option for those seeking a gentler, natural alternative.
👉 For best results, consult a dermatologist or urologist before starting the supplement, especially if you are combining it with other treatments.
