Dreadlocks fall apart for several reasons, however the crochet method will almost always be your best solution.
If your dreadlocks are unraveling after being twisted we highly suggest switching to the crochet method, since your hair clearly will not hold a standard twist.
If your dreadlocks young and interlocked, backcomed, or twist and ripped, and coming undone we also recommend switching to the crochet method. In addition to switching methods we recommend avoiding the use of “locking gels”, conditioners, and excessive wax as these can inhibit and actually prevent your dreadlocks from locking and tightening up properly.
