just a stab in the dark, a few things came to mind:
do you detangle? maybe you need to run your fingers through it.
maybe you have same nasty build up from the condish
maybe you need somthing with slip, marshmallow root is amazing, works wonders for my hair, and oils are a good slip as well, if your worryed bout being weighed down, then a light oil, like jojoba or argan.
a deep conditioning treatment wouldnt hurt it either.
hope there are a few thoughts there for ya

my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
