Build-up, probably. DevaCurl, from what I understand is fairly moisturizing with a good dose of protein. If your hair has had its fill of moisture/protein, it will start to repel the product, rather than absorb it, except your hair is high porosity (which absorbs practically anything).
How often do you go through these steps?
While I haven't used DevaCurl personally, my low porosity hair repels a lot of things, and a lot of gels and conditioners just don't mix on my hair. I get the white-ish effect when I use too much of a thicker product.
To answer your question directly about the product: I don't think it's because you're putting in too much product at a time. Also, my advice is based on the assumption that this white ball business has not occurred before.
