Instant locs are locs created using back combing (teasing) and crocheting. This method of hair locking is normally used to loc straight or longer curl patterns. It is also used to speed up the initial locking process or "skip the ugly phase" as some would say.

Dreadlocks are essentially entangled locks of hair achieved through various means of rolling hair. It's hard to tell who had them first, because early humans, lacking combs or styling products, probably roamed the planet with matted hair.
