Introduction to No-Wash Ampoule Treatment

My hair is very fine and weak, so when I get a perm or dye it, the ends get damaged and the curls don't come out.

I got a perm to style my hair up for the summer, but I still have no curls. It looks like a broom... ㅠㅠ

However, if you spray the ampoule treatment and touch your curls, curls form even without blow-drying.

I don't usually blow-dry my hair, but when I do, it creates lots of curls that last a long time.
