Cornrows have been a major part of the African heritage, from showing the tribe you are a part of to showing your social standing. This hair style is still going strong today. There are so many variations of cornrows that it is really impossible to take away from the true beauty that some expert braiders can invoke from these braids.
Dreadlocks have been a way of styling and maintaining hair for many years by many different people for many different reasons. For some people it's for religious reasons, for others it's just the only thing they have known all their life and for others too it's seemingly an escape from having to overly manipulate their hair.
