Bumping this thread up because I have many of these same woes. Front and sides are pretty curly, the back is wavy and much straighter than the rest of my head. Since starting CG the crown and back of my hair has been disgustingly oily, though the front and sides are reacting fine. I'm not even sure what to do. The back of my head is superoily even after having low-poo'ed with AO's GPB shampoo and conditioner. I'm carrying on with a CG routine because my hair is so damn frizzy. If I use regular poo and brush out my hair the back looks good but the front and sides get super frizzy. If I CG the front and sides look good for a day or two but the back gets superoily. Ugh. I don't know what to do but I feel your pain, fellow wavies.
