Dread loops are just one of those weird dread-things that tend to happen... don't try to understand them, just gotta love them for what they are. And if they are really bugging you and it won't cause your lock to unravel, just try snipping it off. We've found that these loops sort of have a lifespan, as well... they're like pimples... you sorta notice it at first, then one day they're HUGE and that's all you can see. And then eventually, after about 4-6 months when they’re at their worst, they get sucked back into the lock, or just get small and hard to notice. So, again, like most things with dreadlocks, they just take time and patience!

Knotty Sam has something to say about those lumpy loops too...

"I had a huge problem with dread lumps/loops and I found an effective way of making them go down faster. Buy plastic coated wire from an arts and crafts store and coil it around the loop and leave it there for a few days.
It makes them go into the dread faster and it looks pretty cool with the colors."
