The term 'flat braid' is a type of hairstyle that involves braiding the hair in a flat pattern. It is also known as a cornrow, which is a seven-letter word that is used to describe this particular style. This hairstyle is often seen in African American culture and is a popular choice for those who want to keep their hair neat and tidy. The flat braid is created by weaving the hair into small, tight braids that are close to the scalp. This style can be worn for a variety of occasions and can be customized with different colors and patterns.
