The Pino hair mask pack is good.

There was a promotion offering free shipping on two purchases, so I bought two, and I'm really glad I did. After using this, my hair has more volume and feels great. They said you only need about 500 won worth, but since I have short hair, I use about 100 won. The downside is that since you scoop it out, the hygiene is a bit of a concern. Aside from that, it's good.
