How can I condition my dry, coarse, low porosity, and curly hair?
Your hair sound very similar to mine except mine is 4c. But since your hair is dry and low porosity I think you need a good leave in conditioner for your hair and a great sealant. If oils aren't enough to seal in moisture you might need something heavier like butters. What works for me might not work for you but I hope something in this is somewhat helpful lol.
You need to deep condition with heat that way the conditioner can actually penetrate your haire
