Welcome. Crocheting is the most damaging thing that can be done to locks. Locks take time to grow, not effort. Effort only damages them.
Crocheting breaks hairs into smaller and smaller pieces with each pass back and forth through your lock. This weakens them to the point where they can snap off, and even fall out at the root, leaving a bald spot
welcome but never ever crochet dreads its pure destruction and delays progress by 6 months or more
its a horible abusive thing to do to dreads
Welcome and Happy Dreading..
