Until you determine your hair properties, it's difficult to give you answers to your questions. You also need to disclose the name of the product and/or ingredients. You're asking people to advise you with no, or limited, information.

My fine/low porosity hair loves protein, doesn't like a lot of chemicals (especially polyquats.) For me, a product with keratin, but without polyquats, would be great. Depending on you properties, it may or may not be the case for you.
