Our dread soap cleans the hair and leaves no residue behind. It actually helps your dreads tighten,(How?) because it gets the hair so clean and free of oils that the hair will bind, knot,dread, and tighten faster than it normally would. Many soaps make the claim that they clean hair, but these same soaps leave scents,conditioners, moisturizers, and other additives behind, which leave the hair far from clean. The scents, oils, and goo, in their customers hair, are evidence that these soaps are not doing a good job of cleaning. These things build up in your dreads and destroy them by lubricating the hairs, and loosening your knots. Soap that leaves residue on the scalp not only slows down the dreading process but it can cause itching and irritation on the scalp.
