Dreadlocks, also known as locs or dreads, are rope-like strands of hair formed by matting or braiding hair. They can be created by allowing textured, uncombed hair to bunch and naturally knot together over time, or by braiding and twisting hair together. Dreadlocks have been worn for religious, cultural, and spiritual reasons, and have become a popular aesthetic in modern fashion, music, and beauty. The exact origin of dreadlocks is unknown, but there is evidence that people wore them thousands of years ago in Europe, Asia, Africa, and the Americas. Dreadlocks can be created by neglecting hair completely, or by using other methods such as dread braiding, twisting, and backcombing. Locs are an African hairstyle that consists of hair strands that have been coiled, braided, twisted, or palm-rolled to create a rope-like appearance. The terms "locs" and "dreadlocks" are often used interchangeably, but some people believe that "dreadlocks" has negative connotations and prefer to use "locs" instead.
