I have a similar problem! I've been using LA Looks Sport Look Gel for a while, and all of a sudden, it's been flaking out on me! I wouldn't even use a lot and I would still get flakes. At first, I thought it was build up problems, but I shampooed yesterday, and I got flakes today. I even stratched my head to see if there was build up, and I had none.
ETA: I have a thread about this. I'll bump it for you!
