I tried it once, and I didn't like the way my hair looked afterward, it looked really unhealthy and singed, a lot of the hair broke off, and it smelled so bad. The tips didn't have the blunt look I was looking for either they just looked fried. If you are going to do it make sure you don't have any wax or products in your hair, most hair products are very flammable. But I got the best results just rolling the tips in my palms.

You should pull them apart and then put a rubber band around the loose hairs, wax them and palm roll. And keep an eye on them, because if it happened once it can happen again.

The best way to tighten them is to palm roll them. Palm roll has amazing affects.

The best way is to put a bead over the lump and take it off in two months.

The rubber band at the tip is used to help keep the dreads together when they are new and it helps the tip lock up once the dreads are tight. If it is just a regular rubber band then you should just leave it there until it falls off, but if it is one of those super Scunci elastics then it will never fall off, you should take it off after three months.
