Back in the day using actual hooks on dreadlocks was hardly even known. When people talked about crocheting dreadlocks they were talking about a technique described below where the dreads are pulled through themselves to take up slack in the dread. This technique is now known as interlocking. It’s not just a maintenance technique, it’s actually used to start the dreads. Interlocking techniques are used primarily for micro “dreads” in African textured hair. In larger dreads, and in straighter hair textures, the technique is not usually used because of the thin, wrapped/braided look that it leaves.
