Knotless braids are generally created by using synthetic hair to help add thickness as well as supporting the real hair in the braid also. Because they are not attached to the scalp like other similar styles such as cornrows, box braids can be styled in a number of different ways. The installation process of box braids can be lengthy, but once installed they can last for 6–8 weeks. They are known for being easy to maintain. However, these braids can also be done with natural hair.
