Original: Dreadlocks, also called locks, a ras, dreads, or Jatayein (Hindi), are matted coils of hair. Dreadlocks are usually intentionally formed; because of the variety of different hair textures, various methods are used to encourage the formation of locks such as backcombing.
Simplified: Dreadlocks, also called locks or dreads, are coils of hair which are made by themselves, in all hair types, if the hair is allowed to grow naturally without grooming for a long time.
