Mise-en-scène Serum Shampoo

When you think of Mise-en-scène, you think of Perfect Serum.

It's really famous, you know!

They say it's a shampoo infused with the nutrients of that serum🧡

It's my first time hearing about serum shampoo, but since it's a shampoo, I'm really curious because it seems like it would nourish my hair in a fresh way compared to just using serum.
