R.N.
My son is biracial and has coarse hair (both curly and straight). I use a product on his hair that is called Mixed Chicks. It has worked wonders on his hair. I also do a cococut oil (Hot oil) treatment to his hair that works great. Cococut is a natural relaxer. I buy a tib of it at the health food store and buy a bottle from a beauty supply store (that you would use to appky hair dye). I fill the bottle about half way and then put the bottle in hot water to liquify the oil. Once it is liquified, I apply the oil to his hair and scalp. I let it sit for about 5 minutes (my son is only 3 so its hard to get him to sit still for very much longer). It makes his hair silky and so very soft.
