Shampoo for Thinning Hair?

What is the best shampoo for thinning hair ?

I saw this shampoo called Nano on the internet which is made by a doctor ,what do you think about it ? Thank you for your time !

Just because its made or promoted by a doctor doesn’t mean it’s going to work.

There are no shampoos that are proven to regrow hair, but some suggest Nizoral (ketoconazole) works for some men. I’m not recommending everyone run out and by Nizoral to treat hair loss, and to be honest, I’m skeptical that it even works. There aren’t proper studies that show ketoconazole is good for hair regrowth, though it is a good anti-fungal shampoo. With that said, I suppose it’s worth a shot if you’re only considering using shampoo to treat your hair loss (which is a bad idea).

The best way to go about this is to talk to a doctor about Propecia, which is a proven treatment for hair loss and is just one pill daily.
