Of course, they grow just like normal hair. Your normal straight hair grows out of your scalp and then it grows into the rest of the dread.

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.

The best thing to do is roll the tip of the dread in the palm of your hand. This will make nice little round tips. I rolled my tips for three months and now they are round and really nice.

Dreads do get fatter with time, because the hair that would have fallen out, builds up inside the dread. This is what makes the dreads become hard after a while. But if you want really big dreads and you haven't started them yet it's easy to make them fat, just make bigger sections. And it's pretty easy to make the bigger if the dreads are only about two months old or younger, just rubber band them together and palm roll them as much as you can. But once they are hard it's really hard to connect them, you can still rubber band them together, but you take a chance of having folds or creases in your dreads.

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 can tie string around the roots and make them grow in thinner sections, but if cut them or pull them apart it really tears up the dread.

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.
