I have tried both and they were kinda too conditioning for me too. HCC very much so and the GL one a bit less. It actually seemed to work great for a while when I first started using it. I think I used it for about 2 months before I had to declair myself defeted. So it worked for longer than most but ended up being a bit too mild for me.
But I think it is well worth a try. All hairs are so different.
