I have the Giovanni and it does work well but I found if I used it too much it kinda dried me out, To get around that I added some conditioner to the length and focused mainly on the scalp then gently combed my fingers through the length to distribute it before rinsing. I also found that along with my hard water I was using the wrong conditioner to cowash. It turned out I couldn't use just any condish I needed a clarifying one. The VO5 ones ended up working great, are supercheap and have EDTA in them which helps get rid of hard water buildup. HTH.
