Please recommend a hair product (shampoo) that is good for relieving hair loss and itching.

As I get older, my hair is getting thinner, so I'm worried about hair loss and am using hair loss shampoo.

The effect is minimal...

I wonder if it's because of the changing seasons, or if my hair loss is about to start...

My head feels so itchy these days.

If anyone knows of any hair products (shampoos) that help relieve itching, please recommend them.
