Mise-en-scène Perfect Serum

This is Mise-en-scène Perfect Serum.
I understand that it comes in five varieties, but the product I use is the original.
During the rainy season, the high humidity often makes your hair feel heavy.
However, when I use this product, my hair gains elasticity, so the volume doesn't flatten out.
I also experienced improvements in hair tangling and breakage when using it frequently, not just during the rainy season.
