Drealocks, sometimes simply called locks or dreads, are interlocked coils of hair which tend to form by themselves, in all hair types, if the hair is allowed to grow naturally without the use of brushes, combs, razors, or scissors for a long period of time. Many religions and cultures specifically forbid wearers to cut their hair. It is common for wearers to perform thorough maintenance on their hair, including regular washing and various techniques of re-knotting, in order to maintain the desired appearance. Although the term dreadlock is associated closely with the Rastafari movement community, people of various cultures have worn, and continue to wear, locks.
