I don't see how the hell SP even compares to finasteride. Found the original study. It is so misleading
[h=2]Abstract[/h]The objective of this open label study is to determine the effectiveness of Serenoa repens in treating male androgenetic alopecia (Androgenetic Alopecia), by comparing its results with finasteride. For this purpose, we enrolled 100 male patients with clinically diagnosed mild to moderate Androgenetic Alopecia. One group received Serenoa repens 320 mg every day for 24 months, while the other received finasteride 1 mg every day for the same period. In order to assess the efficacy of the treatments, a score index based on the comparison of the global photos taken at the beginning (T0) and at the end (T24) of the treatment, was used. The results showed that only 38% of patients treated with Serenoa repens had an increase in hair growth, while 68% of those treated with finasteride noted an improvement. Moreover finasteride was more effective for more than half of the patients (33 of 50, i.e. 66%), with level II and III alopecia. We can summarize our results by observing that Serenoa repens could lead to an improvement of androgenetic alopecia, while finasteride confirmed its efficacy. We also clinically observed, that finasteride acts in both the front area and the vertex, while Serenoa repens prevalently in the vertex. Obviously other studies will be necessary to clarify the mechanisms that cause the different responses of these two treatments.
68% noted improvement with Finasteride vs 38% for SP, how could they argue SP is better? Stupidity like this is why we can't take PSO or other herbal remedies seriously. Something just doesn't seem right.
