Hold crochet hook with dominate hand, needle facing toward you, hold dreadlock with left hand. In a spot with numerous loose hairs poke needle through dreadlock to other side. Grab loose hairs with needle and pull them through the dreadlock (use hands to keep loose hairs on hook if necessary and to hook more hairs). Be sure to curve crochet hook out of dreadlock so it will not pull loose hairs out the other side. Do not pull crochet needle straight out, this will rip the hair and strip it.
