Is Saw Palmetto a good drug for blocking DHT?

Hi, I didn’t understand if Saw Palmetto can decrease dht levels in blood and if it can do a visible results in hair health. Because i know that finasteride is the n#1 remedy used for AGA. Saw Palmetto should be a sort of ‘natural propecia’, less effective but without relevant sides as finasteride. But i really don’t understand if a man can have results in hair density and regrowth taking only saw palmetto. I mean if the starting situation of hair is not so bad (a little thinning hair but not bald at all).

There are many studies that show that Saw Palmetto is a very weak and poor DHT blocker for hair loss. Intersting read: https://baldingblog.com/general-questions-on-dht-blocking-supplements-have-birth-defect-risks/
