i have the exact same issues. My hair never gets/keeps enough moisture. There was a recent thread on this topic but I couldn't locate it. I am porous also and looking for the same results as you - decreased frizz, volume and softness. I don't do well with oils/butters either. I did the stretch test and my hair seems a little brittle so maybe a bit over proteined. Would love to find a product to up the moisture quotient!!! Hope others chime in with help.
