I believe that hair can also be naturally porous. Maybe SW can correct me if I'm wrong. It doesn't have to be chemically treated to be porous and soak up products.

Hypothetically, would the right products for your hair and the right "frequency" of use be important? If your high porosity curl looses product as fast as it absorbs it, then would more frequent DTs help your hair or be a waste of product?
