Anyone tried NuHair supplements?

I saw these at Walgreens, marketed as a DHT blocker supplement. It contains: Saw Palmetto, Phytosterol, He Shou Wu (Fo Ti), Zinc, Selenium, Kudzu, and Soy. Seems like relevant components that are often mentioned as helpful for hair.

1) Anyone tried these? Any positive effects?

2) Any side effects from these ingredients? I hear saw palmetto might have sides?

Thanks.

Posts like this make me wonder if people actually watch/listen to the show. There are 2 FDA approved treatments for hair loss. All these other products you see will provide minimal/no benefit to people suffering from mpb.
