For me and a lot of other people on this board, Deva products really just aren't that good! I personally find them drying and not very curl enhancing. I suggest looking into different products that will work better for your hair
What are your hair's properties? Fine, thin, thick, coarse, low porosity, high porosity? Stuff like that is the most important in choosing what kind of products to use to make your hair reach its maximum awesomeness!
