Mise en Scène Perfect Serum, bought with my own money

Mise en Scène Perfect Serum Original provides the necessary nutrients to your hair with 7 types of oil ingredients.
The formula is on the slightly viscous side, so it leaves a bit of residue after use.

And it smells good enough that you don't need to spray perfume separately.
I like it because after using it, the surface of the hair becomes smooth and shiny, and the texture becomes calm.
If you are looking for a cost-effective hair serum, I recommend Mise en Scène Perfect Serum.
