Hey,Dusa. I didnt know why I could not use it every day but I guess I do now. For one thing, it has protein, and if I didnt know that then, I know it now, and I know why it doesnt work well on my hair. Neither did Shea cashmere and I could not figure that out either, consequently, I have a full bottle that I will probably never use. So, it may have been the protein, or the overconditioning. GVP may do the same so I am coming to the conclusion that I need a lighter conditioner in between, or on alternative days, like cure care (which also has protein but is a lighter conditioner) or a Suave or a Yes to.But both the GVP and the Smooth as Silk are great, and you dont need a lot of the Smooth.
