I had Carlos cut my hair and also bought the gel before leaving. When he did my hair with it, it worked OK but not great. I like a fair bit of volume, which I didn't get from it, even when I tried it at home. But I haven't given up on it yet. I'm going to try mixing it with a clear, stronger gel (his is kind of white opaque with not a lot of hold) and see how that works.
I didn't buy the co-wash or the conditioner because I have products coming out of my eyeballs!
