Nothing more than all the things I've already suggested.

Unless you're bound and determined to be strictly CG, why not shampoo? Many of us find we simply need to. If not that, you may just need to co-wash more than twice a week. If you're not itching, it sounds almost more like product build-up flaking than anything - be careful about overdoing it with styling products, especially on the scalp. However often you co-wash or low-poo, it's important for anyone to scrub their scalp well, especially if not using shampoo.
