Do I Need to Use Saw Palmetto Forever?

Hey Dr. Rassman, I was just wondering if I took saw palmetto and saw some results and then stopped using it, would that have the same effect as taking propecia and then stopping its use. I know after one stops taking propecia all that hair is lost, would that be the same outcome of stopping saw palmetto?

Thanks

If the claimed DHT blocking occurs with saw palmetto, then I suspect that if/when you stop it, the maintained hair would be lost under the exact same mechanism as Propecia (finasteride).
