Generally, it takes about 3 to 6 months to attain the full dreads, but this depends on the softness of the hair. The softer the hair, the longer the time and vice versa. The nature of the hair also affects the duration of the formation of the dreadlock. If the hair has a full body, it makes the formation easier and faster. Scanty hair takes more time. There is also some super dread kit that can act as a catalyst. They will help the formation of your dread come faster than expected, although this might be quite expensive and it helps a lot.
