The extract, the fruits as well as the bark of the tree have been used as a traditional medicine in Africa for centuries to treat different ailments such as infections and inflammation. Pygeum extract shows promise as a natural treatment for hair loss due to its DHT blocking effects. Whether its effects are due to its fatty acids, anti-inflammatory properties or the beta-sitosterol in contains (Stewart, 2003) remains to be researched further, but there are numerous studies showing its potential DHT inhibiting properties in patients suffering from an enlarged prostate and even from prostate cancer.
The authors mention that this particular mechanism is similar to the one of finasteride and could lead to developing a new similar drug without the severe side effects
How to Trigger Rapid Hair Growth
Hair follicles in the scalp can be sensitive to DHT, which causes them to miniaturise over time, gradually making hair thinner and eventually causing baldness.
Androgenic alopecia’s pathogenesis is androgen dependent, meaning that the androgen receptor (AR) gene is one of the main culprits for its early onset (Hilmer et al., 2005). This may be one of the reasons why pygeum is an effective treatment for hair loss as researchers noticed that it inhibits the human AR, which contributes to growth of the prostate gland and to alopecia.
The 5 alpha-reductase (5AR) inhibiting mechanism is due to the isolated N-butylbenzene-sulfonamide (NBBS) compound in pygeum, which is a specific AR antagonist. (Papaioannou et al., 2010)
Cysteine, lysine and serine
A scientific paper (Cabeza et al., 2016) reviewed drugs used for androgen dependent diseases. Among them, Pygeum’s mechanism that enables the inhibition of the 5AR enzyme is based on the formation of an enzyme steroid complex with a nucleophilic part composed of substances like cysteine, lysine and serine. The authors mention that this particular mechanism is similar to the one of finasteride and could lead to developing a new similar drug without the severe side effects.
Pygeum and nettle
the best results were seen when they were used together
Pygeum is more effective than nettle. Nettle and pygeum combined are more effective than pygeum alone.
Other studies seem to confirm these effects: when pygeum was studied in relation to nettle root extracts, researchers found that they significantly blocked the action of 5 alpha reductase and aromatase, which caused a decrease in DHT. When nettle root and pygeum effects were compared against each other, pygeum extract was the one showing higher efficacy even in low doses, but the best results were seen when they were used together. (Ghorbanibirgani et al., 2013; Hartman et al., 1996)
Pygeum compared to Finasteride, saw palmetto and Tamosuosin
Pygeum: 43.3% improvement. Finasteride: 57% improvement. Saw palmetto: 42.7% improvement.
In another study (Hutchinson et al., 2007), 2559 patients suffering from BPH and following a various set of treatments were compared with patients that were simply supervised without following any treatment. The treatments followed by the first group included: finasteride, saw palmetto, tamosulosin, and pygeum. After a year, there was a significant improvement registered for the group that received treatment when compared to the untreated group but the results varied according to the type of treatment received. Those who were taking a treatment involving pygeum had 43.3% improvement, comparable to the results for finasteride (57% improvement). Also, the patients that were receiving pygeum africanum had a slightly better improvement rate when compared to those who were treated with saw palmetto (42.7 %).

These studies confirm that pygeum may have similar, if not better effects than saw palmetto. This, however, also depends on the dosage and each individuals, as some might respond better to one plant than the other.
Antioxidant and anti-inflammatory properties
Besides being a 5AR inhibitor, pygeum is also a good source of antioxidants which may help nourish hair and protect it from free radicals. Various studies (Oktay et al., 2003; Steenkamp et al., Feng et al., 1995) have shown that the extract of pygeum has excellent antioxidative properties.
Studies on animals have shown that pygeum has a significant anti-inflammatory activity by decreasing the production of leukotrienes, 5-lipoxygenase metabolites and inhibiting fibroblast production. (Boulbès et al., 2006)(Quiles et al.,2010) Other studies (Cristoni et al.,2000, Stewart,2003) have also confirmed these anti-inflammatory effects. Since people with hair loss usually present significant inflammation of the scalp, pygeum could also be used as an adjuvant in hair loss treatments. Furthermore, these beneficial effects make pygeum a superior treatment to saw palmetto since it also reduces inflammation.
As for dosages, in most studies, pygeum is taken in two 200mg doses per day as a maximum dosage but studies have shown that a single dosage of 100mg per day or two dosages of 50mg per day have shown significant effects and are safe even after a 12 months of continuous usage. (Chatelain et al., 1999) The extract can be found on its own or part of a supplement either for hair loss or prostate enlargement, in combination with other natural ingredients such as saw palmetto or nettle root.
The side effects when taking this extract have been shown by most studies to be minimal and mostly include a mild stomach upset.

Pygeum is an endangered species
Whatever product you choose, make sure that the pygeum is extracted from a responsible source; since the pygeum plant is an endangered species.
Pygeum africanum could be a potential treatment for hair loss due to its DHT inhibiting effects but also due to the fact that it may also reduce inflammation in the scalp. Further research is needed to completely understand the substance’s potential and efficacy but its effects are similar to saw palmetto and even superior according to one study, which compared the both. Fortunately, the extract is safe to take as a supplement so those suffering from androgenic alopecia should try it on its own or in combination with other treatments they are taking. As a precaution, always ask your physician before taking any supplements, especially if you follow other treatments.
Most importantly, make absolute certain you tell your doctor that you’ve taken pygeum supplements before having your prostate examination — pygeum is likely to effect prostate size and therefore may influence the result of your prostate exam.
