Maintaining dreadlocks is very different from maintaining other natural hair styles. Dreadlocks don’t need to be brushed and don’t require regular trimming. Like other natural hair styles dreadlocks need to be kept clean. Contrary to popular belief clean dreads lock up and tighten faster than dirty dreads.
While other natural hair styles require combing to put stray hairs back in place, dreadlocks need to have stray hairs tucked back into the dread so they can dread up and lock with the rest of the hair. You'll also notice that dreadlocks look better and better over time. As they continue to mature they become tighter and smoother and they require less maintenance.
Your maintenance routine will vary depending on the age of your dreads and the method you used to start them. The two most popular methods for starting and maintaining dreadlocks in natural black hair are twisting/palmrolling and latching.
