Locs are short for dreadlocks, a hairstyle in which strands of hair that would normally shed or be combed out lock together into thick coils. Hair is not combed during the locking process and has to be washed carefully to prevent the loss of natural oils that aid in locking.
The method for creating locs varies depending on the texture of the hair being locked. Some types of hair form locs naturally if not combed or cut, while other hair types need to be encouraged with methods such as backcombing. According to stylist Maria Thompson, visiting a stylist who specializes in locs is the best way to build an appropriate locking regimen.
