Box braids are a popular protective hairstyle that involves dividing the hair into small, square-shaped sections, or "boxes," and then braiding each section. This technique can be done with natural hair or with the addition of synthetic or human hair extensions to add length and volume. The style is versatile and can be worn in various lengths and thicknesses, making it suitable for different hair types. Box braids can last several weeks with proper care, providing a low-maintenance option for individuals looking to protect their natural hair while expressing their personal style.
