I’m liking it

I’ve seen many describe the smell as unpleasant but I like it. My hair has started feeling a lot more healthy and not seeing as much shedding

It’s very stinky

Yall this stuff does stink. It smells like vegan leather fresh out of a plastic bag. I agree with the other reviewers. Yes the stink does go away after some time but it’s not good.
