There have been several articles published in the last few years about efficiency of saw palmetto (serenoa repens) to hair loss. We would like to bring a little bit light to this topic now.
The Saw Palmetto (serenoa repens) is a small, bush-like palm with long-branched leaves and big, dark red fruit. It comes from America, where it was widely used by Indians for centuries; after 1990, modern medicine started to recognise its health effects.
Extract from the Saw Palmetto fruit is rich in fatty acids and phytosterols, and is the most-used natural product in America and Europe in the treatment of Benign prostatic hyperplasia (BPH) and hair loss for both men and women.
Some studies show that Saw palmetto extract is an effective antiandrogen that blocks izoensyme 5-alpha reductase and androgen receptors on the membranes of hair follicle cells.
Main Cause Of Hair Loss And Saw Palmetto (serenoa Repens) Role
Many people experience hair loss problems at some point of their lives. Also referred to as Androgenetic Alopecia, hair loss is common in both men and women as everyone ages. Testosterone is the culprit behind it, as its conversion into DHT causes the hair follicles to shrink, thereby resulting into hair loss. Since men have higher testosterone levels than women, balding is mostly common in men.
In most cases, men experience thinning of hair in an M-shaped pattern, also referred to as the male pattern baldness. More about balding here: https://gettik.com/signs-of-balding/
In women, thinning typically occurs all over the scalp, though it rarely results in complete baldness.
To curb this problem, there are many different kinds of hair loss remedies that can be broadly categorized into natural and artificial remedies.
While artificial treatments for hair loss are sometime effective, most have serious side effects and their prices are out of reach for many people. Natural and herbal remedies for hair loss are increasingly becoming popular, as they have proven effective in slowing down hair loss and even encouraging hair growth.

Saw Palmetto And Other DHT Blocker Finasteride
Saw palmetto is one of the most popular herbal remedies for hair loss. Sufferers of hair loss owe its effectiveness in its suggested similarity to finasteride, a popular treatment for enlarged prostate. The 5 mg. finasteride tablet (Proscar) is used for the treatment of enlarged prostates, while 1 mg finasteride (Propecia) is used for hair loss treatment.
One of the most important and active ingredient of the saw palmetto, berry extract, acts as an effective inhibitor of the production of DHT. It is a chemical molecule associated with testosterone-related hair loss and prostate enlargement. Besides blocking the production of DHT, this saw palmetto berry extract also helps to block other forms of hormone-related hair loss.
Decreasing Of The Production Of DHT:
Serenoa Repens vs Finasterid
In a sample consisting of 1098 men, the studies lasted for 6 months, during which Saw Palmetto extract was administered to one group and finasteride was administered to the other. Patients did not know whether they were given finasteride or Saw Palmetto extract. Both substances had a similar positive effect on the patients‘ health. A great reduction urination problems was observed, a condition which was caused by excessive production of DHT. However, in 9% of the patients to whom finasteride was administered, a decrease in sexual activity and libido was observed. In contrast, in 6% of the patients to whom Saw Palmetto extract was administered, an increase in sexual activity and libido was observed.
Clinical trials have also demonstrated that saw palmetto can lower the levels of DHT. According to the study, saw palmetto is not as effective as finasteride that reduces the levels of DHT by about 70%, but it still produces a significant result.
People with mild androgenetic alopecia, lowering DHT levels by 32% is likely to be significant enough in slowing down the progression of hair loss.
This is well-regarded as being a top natural hair growth product and one of the necessary ones to keep in mind.
Countless years of research has gone into learning the intricacies of saw palmetto and what it brings to your hair growth journey. In general, saw palmetto is designed to act as a growth factor to help the body enhance hair development. It is a neat addition and something that is biologically sound with its impact.

SAW PALMETTO | How does it work To STOP HAIR LOSS
Saw Palmetto extract is a natural DHT blocker which reduces the level of harmful dihydrotestosterone ( DHT ) in the body thereby terminating the reduction of hair loss.
Is Saw Palmetto (serenoa repens) Effective for Hair Loss Treatment?
Saw Palmetto (serenoa repens) Studies Againts Hair Loss
Studies on whether saw palmetto is an effective treatment for hair loss is quite limited but very promising.
Research at the University of Florida and other research centres in Germany has shown that Saw Palmetto extract has many similar effects to finasteride and that it rapidly decreases the level of DHT in both women’s and men’s bodies.
1. In a major 2 year international study, the effects of Saw Palmetto extract and finasteride were compared.
Table: Score after 2 years of 2 groups with androgenic alopecia. First group of 50 male received 1mg Finasteride everyday and second group of 50 male received 320mg Saw Palmetto (Serenoa Repens) everyday.
Based on the study we can confirm that saw palmetto has anti-hair loss effects.
Finasteride is more efficient. However, it should be taken into account that saw palmetto is a natural product with less side effects than finasteride.
From study: “In our opinion, serenoa repens could be considered as a valid approach in treating low or moderate AGA, and a good alternative for patients in whom finasteride or other topical therapies cannot be used.”
2. In one study that appeared in the Journal of Alternative and Complementary Medicine in August 2002, 60% of the participants who took 400mg saw palmetto combined with 100mg of beta-sitosterol exhibited significantly more hair-growth than those who took a placebo. However, with a rather sample size of only 19 participants, and the use of another drug makes it difficult to tell if the improvement in hair growth was due to the saw palmetto or beta-sitosterol.
3. Another small study of 10 men from 23 to 64 years with mid androgenic alopecia. It shows effectivness of natural ihibitors (the liposterolic extract of Serenoa repens (LSESr) and beta-sitosterol) againts AGA
4. Further research on saw palmetto published in the Journal of Cutaneous and Aesthetic Surgery, and done by Sundaram Murugusundram found that the topical application of the plant’s extract in shampoo and lotion base for three months increased the hair density of participants by 35%.
If the available research and online testimonials/reviews for saw palmetto are anything to go by, then it’s safe to say that it’s good for hair loss. In most of the cases, no serious side effects were reported by the users, though the products are not recommended for use on children. Nonetheless, there are some users who reported mild side effects like stomach irritation and headaches (we’ll talk about these in detail below), and these can be avoided by taking the extract with food.
How To USE Hair Saw Palmetto
To achieve the same effect as taking 1mg of Finasteride (Propecia), the most effective daily dose of Saw Palmetto extract is 320mg.
It is very important that it be a standardised extract containing 85-95% of fatty acids and 0,2-0,4% of sterols.
Many hair-loss preventon preparations do not contain the extract in sufficient amounts, or they contain a powder from the Saw Palmetto fruit, which is not sufficient to decrease DHT levels in humans. For instance, a preparation of Folixil contains only 120mg of this extract in one pastille.
Saw palmetto usually comes in the following forms:
Although saw palmetto can be brewed into some tasty tea, it’s highly unlikely that it will be effective in treating hair loss, since the active ingredients are not water soluble.
The liquid extracts and whole berries can be taken either by ingesting them or applying them topically. Nonetheless, research on the effectiveness of liquid saw palmetto extract and whole saw palmetto berry is limited. One study confirmed effectivness of liquid form but after 4 weeks it recommended to start to use concentrated serenoa repens => study
Capsules and tablets that contain the saw palmetto are therefore your best bet for using the plant’s powerful effects on the treatment of alopecia. Many formulations of the product can be purchased online, as well as in the brick and mortar nutritional supplement or health food stores.
Capsules and tablets are the easiest to find, since they are the only forms that have been widely examined by researchers. As we have already mentioned, be sure to choose saw palmetto capsules/tablets made by a reputable company, and read the label carefully to make sure the content is standardized to contain between 85% to 95% of sterols and fatty acids.
Daily use of saw palmetto (serenoa repens)
Don’t forget that the saw palmetto dosage is not an instant cure-all. With daily use, give it at least two months for the results to appear. In about 60 days, you should start noticing whether the hair loss has reduced, and if the thickness of your existing hair has been improved. The full results should be seen in about 6 months to a year from the time you start the saw palmetto treatment.
Other natural and botanical remedies can help to improve the efficacy of saw palmetto when combined in the treatment. Some of these include biotin, L-Cysteine, Green Tea, and Vitamin B-2, which have all been shown to promote hair growth and stop hair loss.
The general idea about using saw palmetto for hair loss is to improve hair thickness, slow down the rate of hair loss, and to allow other hair loss treatments to work more effectively.
Experts recommend a dose of 160 milligrams twice a day for the treatment of enlarged prostate. However, since it’s not an approved hair-loss treatment, the proper dosage for hair loss treatment is still a conjecture.
As a rule of thumb, always consult your doctor about safe dosage amounts before you start taking any new supplement.
Possible Side Effects and Other Interactions
Saw Palmetto extract corrects the functioning of our endocryne system. It helps address troubles with the prostate and hair loss, but also menstrual pain and inflammation of the ovaries. The extract has also anabolical effects and works as an aphrodisiac.
Just as with all treatments, it’s important to consider the possible side effects and interactions before you start using saw palmetto for your hair loss treatment. Saw palmetto is generally considered safe, though it’s not recommended for pregnant and nursing mothers, or children. Some of the possible side effects include:
- Allergies: Some allergic reactions are associated with the use of saw palmetto. In a study conducted among its users to test its allergic effects, 3 out of 70 participants (4%) developed some form of allergic reactions including itching, swellings, and shortness of breath. If you’re allergic to saw palmetto stop using it immediately.
- Gastro-intestinal side effects: Patients tend to report intestine and stomach disturbances, nausea, abdominal pain, diarrhea, and vomiting. To avoid these problems, take this herbal remedy with food.
- Increased Bleeding: saw palmetto can thin your blood, and lead to excessive bleeding during surgery. Be sure to tell your doctor all the supplements you’re taking before surgery or starting any new form of treatment.
- Dizziness/Weakness: the remedy might in some cases lead to dizziness and general weakness, which might make the patient faint. If you have hormone-sensitive conditions, use the drug with caution.
- Interactions might occur between saw palmetto and other medications. Since it has been shown to thin blood, it should never be taken alongside other blood thinners, such as aspirin and prescriptions like warfarin. And if you’re scheduled for surgery, you should stop using saw palmetto for 2 or more weeks before and after the surgery to avoid excessive bleeding.
- Saw palmetto can potentially interact with finasteride, a drug used to treat enlarged prostate and hair loss. If you’re already taking finasteride, you should consult your prescribing doctor first before you begin taking saw palmetto.
Since saw palmetto interacts with other hormones, it can reduce the efficacy of oral contraceptives. These hormonal effects give it the capacity to interfere with the development or pregnancy, and can have potential effects on breastfeeding mothers. Due to the lack of sufficient information on the possible effects, pregnant and breastfeeding mothers shouldn’t use saw palmetto for hair loss treatment.
