I also have very sensitive, coarse hair I have been experimenting with. I just gave up on coconut oil, my hair actually started breaking and just got oily and looked dirty, even with only using the smallest amount. Olive oil was ok, but still looked oily. Shea butter was better, but still not right. Any proteins were awful. I am playing with jojoba, grapeseed and avocado oil, but I have to be so careful. I would love a DT and LI that keeps moisture better.
3A/3B, coarse, low porosity, high density, iii I believe (?), low to normal elasticity.
