Dreadlock sectioning is an important consideration when it comes to how to start dreads. The brick pattern staggers the sections so the locs in a subsequent row fall between the row beneath them. It creates a slightly more groomed look. My client wanted neat dredlocks so this is the sectioning type we went with. Alternatively, the fan pattern of sectioning creates slightly more natural dreads and has no straight lines in it. You can click here to see an example.
