Olive Young Mise en Scène Perfect Serum purchase

This is the Mise en Scène Perfect Serum. I bought it right away because it was on sale at Olive Young. Since my hair is naturally wavy, it tends to get frizzy and messy, but if I apply just a little bit of this after shampooing, I can really feel it becoming calmer. The scent isn't overpowering; it has a fresh fragrance that makes me feel refreshed. Even applying just a small amount makes my hair feel much better. I was able to buy it at a low price because it was on sale.
