K18
I always buy this product, but the last one was much more liquid than usual and had a different consistency.

It saved my hair
I was on Accutane from last 1 year, which made my hair crazyyyyyyy dry and brittle. Grass might be softer than my hair. I bought K18 and have used it like 3 times so far and I can already feel a difference. I apply it for 4 mins, rinse, and then apply conditioner or mask (to be honest, I have also incorporated Moroccan hydrating hair mask). But after a year probably I was able to go out without heat styling my hair. So happy I bought it.
