Well hello :)
Introduce Yourself
a lot of my tips rounded on their own. i think it had to do with the length and rubbing on my shoulders. the rest of them i rounded by rubbing the tip on my flattened palm. Imagine your dread held like a pencil and your palm is a piece of paper,draw little circles. i like the scratchy tickly feel on my hand. took a long time to happen about a year. It is something i did when i was sitting at a red light or bored waiting somewhere. Many people keep the ends loose. Loose ends wick the water and can help your hair dry faster. It is really just a personal choice. but like Knottysleeves said it won't work on baby dreads.
