I bought this again when I found it. Definitely worth it

I have sensitive skin and my scalp Even more so as it pays the price for the many products I bounce through.
This is like a magic wand. It undoes anything I’ve done to my scalp.
If I feel any scalp sensitivity or irritation, I put a bit of serum on in the evening and it instantly soothes. It continues to calm things down and I usually wake up forgetting I had a problem
It doesn’t leave any stickyness or odd smell like the other products I’ve tried
