I recommend J-Forest hair packs.

I use J-Forest Hair Pack Treatment.

First of all, it smells good and is really, really soft.

I've tried various treatments that are said to be good, so

I've tried pretty much everything famous, but

My favorite is J-Forest.

The downside is that it's a pump type, but the pump head is a bit flimsy lol

I don't like the pump type, so I sometimes put it in a different container to use.
