You don't need to keep TnRing them. By continuing to do it, you are just bringing them back to day one. The twist n Rip method is really just a way to start sectioning your hair. Once it is sectioned, you only need to let them be. They will loosen a bit for a while, but that is only natural. That loosening lets them retangle on their own. What locks need to knot up is to be able to move freely. If you keep manipulating them, they won't get a chance to tangle on their own.
I'm glad you took the bands out. Nothing worse than using rubber bands except for wax and crochet hooks.
And you don't need to palm roll them. It only makes them look tighter for a day or so. When you sleep those loose hairs pop right back out. So it's not like it helps suck in those hairs permanently. And if you palm rollaggressively you run the risk of pulling out hairs from your roots that holed the lock to your head. This can weaken them quite a bit.
All you need to do is TnR them once and let them be. There is a gel from Dreadlockshampoo.com, that actually works pretty well. It's water soluble, so it washes out after each wash. And it even starts to break down before that, so it doesn't leave any residue in your hair.
And then wash wash wash. Wash every 2-3 days for young locks. get a residue free soap. One from that same site is good, or Dr. Bronners, or the baking soda/apple cider vinegar wash works great. if you use a soap, scrub only your scalp. Don't try to wash your locks themselves. As you rinse, he soap will run through them.
And don't be afraid. When you wash, they will loosen up, and might evenuntanglea bit. But that is good. They need to untangle so they can move around and retangle again. The sections will hold their own for the most part.
