Dr. Groot hair loss shampoo

My hair has been falling out so much this year, and I'm worried about hair loss.

My hair is naturally thin and very fine to begin with.

So I bought and am using Dr. Groot hair loss shampoo, but honestly, it feels like my hair is falling out even more.

I thought using it consistently would at least reduce the preventative effect, but lately it's falling out like crazy, like I'm molting.

I think hair loss shampoo is useless.
