I think everyone probably knows about Mise-en-scène Perfect Serum because it is so famous. I apply it to wet hair after washing it, either while drying or after drying. Even if my hair is frizzy, applying the serum immediately calms it down and makes it shiny and bouncy. The scent is also so good that I find myself reaching for it more often. I stopped using it because it was a hassle, but I think I should give it a try again.
