Are you curious about the effects of hair loss shampoo?

These days, there seem to be many different types of hair loss shampoos.

I also tried a few things... I don't think I saw much effect... Maybe it's because I didn't use it consistently;;

Some people say they've seen effects... It also seems like they're promoting the product on the site;;

Which hair loss shampoo is good?

They sell shampoos containing Eoseongcho at beauty salons, so should I use those or pick one from supermarket products? Do you have any effective products?
