Shampoo that doesn't decrease in volume

Hehe, it was literally a beast-sized portion, and a bit of a hit.

It’s a stylish look, and I’m using it because it lathers better than I expected and doesn’t make my hair feel stiff.

But since I wash my hair every day, it feels a bit greasy by evening? Maybe that's why it's not decreasing haha.

It is almost fragrance-free, and the shampoo comes out in a slightly brownish shade.

Nobody uses this. Does anyone around you know about this?
