It depends on what method you use to get dreads.

It depends on what method you use to get dreads.

Elastics are really good for dreads, they help the dreads form the way you want them to and keep loose hairs in. And if you palm roll them while you have them in it will actually dread the hair.

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.

It's not really a good idea, because the dread will start to unravel because the hair that was holding the knots together before is gone. You will have to wait for the tip to lock up again and it's just a pain in the arse. But if you are going to do it the best way to cut it is like a flower, cut it at an angle and then put a rubber band around the tip and rub the tip against the palm of your hand everyday for about 2 days and then take the rubber band out.
