Yes I think coconut oil is light, especially compared to olive and jojoba.
I use 50% coconut, and 50% JBCO. I mix it, and done
The coconut oil makes the JBCO really smooth, that makes it easy to massage with it.
The next morning it has absorbed into my scalp. At least, that's what it feels like. I do not feel the need to co-wash, I usually wash 3 to 4 times a week and that works perfectly fine for me.
