You maybe need to rely on other ingredients for clumping, fatty alcohols are good for this maybe you need more product. Use your coconut oil within a conditioner base or dry pre-wash soaks to reduce porosity.
"Both coconut oil and mineral oil enhance clumping of adjacent hair strands. This mechanism aids in curl formation, definition of curl pattern, and curl retention. Capillary adhesion, the mechanism by which this is possible, occurs when oils form sufficiently thick films on the surfaces of hair strands and capillary forces between adjacent hairs attract them to one another, effectively binding them into clumps.
Researchers found that capillary adhesion between hair fibers remains constant with mineral oil, but is found to decrease over time with coconut oil, olive oil, and sunflower oil. The reason for this is that the very non-polar mineral oil molecules remain on the surface of the cuticle of the hair. In contrast, the saturated or mono-unsaturated fruit and vegetable oils in this study slowly penetrate into the cell membrane complex (CMC) and are transported into the hair shaft.
As this diffusion occurs, the film thickness on the surface of the hair gradually decreases, which diminishes capillary forces. As a result the cuticle scale structure begins to dominate the behavior of the surface of the hair once more, and subsequent tangling and frizz can occur
