Box braids are a popular protective hairstyle that involves dividing the hair into square-shaped sections, or "boxes," and then braiding each section. This style can be created using natural hair or synthetic hair extensions, allowing for various lengths and thicknesses. Box braids are versatile and can be worn in different styles, such as updos or loose. The hairstyle is favored for its low maintenance and ability to protect natural hair from damage. Box braids can last several weeks with proper care, making them a convenient option for individuals looking to reduce daily styling time.
