Has anyone tried Datsu Datsu Shampoo?

My acquaintance's older brother

I made this shampoo in Korea

Take it to Japan and put a Japanese label on it.

I heard they decided to sell it.

I couldn't sell it because something went wrong.

It looks like you are carrying over 1,000 of them.

I feel like I should buy it for him.

I'm a little afraid that I might get skin trouble when I use something I've never used before for the first time.

Actually, I was selected for a product testing group recently.

I was using an ampoule

I had a hard time because I had skin problems on my face.

I heard that the shampoo is being sold on Coupang for around 30,000 won.

Has anyone tried using it?

Should I buy it for you even if I don't use it?

I'm conflicted.
