I recommend Mise-en-scène Perfect Super Rich Serum.

This is the Mise-en-scène Perfect Super Rich Serum. I bought it at Olive Young when it was on sale. My hair is quite damaged, so I purchased it because it is a highly nourishing intensive serum. Compared to other essences I use at home, it has a thicker texture... Is it because it is so nourishing? Haha. It is very convenient to use because it comes in a pump bottle, and I am very satisfied with the white floral scent.

I think all Mise-en-scène products are decent and easy to use.
