Ok so I have the same problem. I'm pretty consistent with separating because I really dislike big congos, I want my dreads to be as thin as possible. So I have no idea how only one of them managed to get completely out of hand, but I guess I'm way past the point of no return now. As mentioned, I only got one big congo dread at the back of my head, I'll include a photo however it's pretty bad quality and I haven't been able to take a better one. So I got this huge thick dread which is basically like a beaver tail and I hate it. When I lay down on a pillow and it gets in a certain position I can feel it pressing against my skull. It's very annoying.
I wish I could just cut it in half or something, but I know that's a no-go from watching Lazydreads did something similar in one of his videos.
I also included another pic of my dreads after something like a year and a half (it will be 2 years in august). They're finally coming along nicely, it's just that I have to wear them up while working and I work all the time, so that must be delaying the process a whole lot. I don't have any other option currently so that just what I have to live with.
I also have a ton of problems with dandruff but I guess that's also very hard to fix easily.
