Your hair may not be absorbing all of the conditioner you're leaving in/on it. My hair is low porosity. I use minute amounts of some of the heavier products. I know it takes longer for my hair to absorb the oils/butters then with lighter products. I do sit under a hard hat bonnet dryer for about 15 minutes on low. Let my hair air dry for about an hour. I can still feel a little of the heavier products on my hair when I SOTC, but it's gone in another hour or so. If it wasn't, I'd think I used too much or it wasn't a product for my hair.
