This is Donggubat shampoo that I bought with my own money.

This is the Donggubat shampoo bar, which has now become very famous.

I initially started using shampoo bars as part of my zero-waste practice, but now I also use them for scalp health. Since it's soap, it doesn't give that silky, silky feeling like shampoo, but you get used to it after a while! The downside is that it dissolves easily in water, so one bar only seems to last about a month, especially since it's expensive. Soaplas treatment is a must. Still, it's good because it reduces plastic waste.
