Coconut oil works wonders. Get your hair wet, towel dry, apply the coconut oil all over (it is a solid when you buy-it's by cooking oil), it's best to leave it in overnight, just make sure to protect pillows if you do. In the morning (or after a long period of time), rinse it out and enjoy your super soft hair.
Sally Beaty Supply sells little packets of protein rich conditioner for about 1.50, my hair is mid back and super thick and I use an entire packet on my hair-if you have less hair, you don't need as much.
