Coarse hair and protein are usually not good friends. Coarse hair does tend to like oils and butters and the products that contain them. They soften the hair and help it to bend. Two off the top of my head are Garnier Fructice Triple Nutrition and Aubrey Organics Honeysuckle and Rose (strong scent). If these were too strong as rinse out conditioners, you could use them as deep treatments. (a blog to help new wavies, go to the how do I get started page)
