The best way to have thin dreads is to make the sections thin when you start them. There really isn't a good way to thin them once you have already put them in. You really can't make the dreadlocks thinner once they are in with the dread braiding method.

There are a couple methods for tightening roots

1. Crocheting- this really shouldn't be used for tightening roots, you should only use it to get rid of loose loops. But what you do is stick the dread through the loop and pull it through; it's kind of like sewing.

2. Clockwise Rubbing- In my opinion this is the best way to tighten roots, what you do is, rub the dread against your scalp in a clockwise motion. It has done wonders for my dreads.

Use the clockwise rubbing method. Rub the dread against your scalp in a clockwise motion.

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

You can braid them in with the braids.

The best way to get round tips is to use the tip rounding technique where you rub the tip of the dread in the palm of your hand in a circular motion.
