13x5 Lace Frontals refer to a type of hairpiece commonly used in the beauty industry. The term "13x5" refers to the size of the lace frontal, which measures 13 inches across the forehead and 5 inches back towards the crown. A lace frontal is a hairpiece that is typically made from human hair or synthetic hair. It is designed to cover the entire hairline from ear to ear and can be used to create a natural-looking hairline for those who suffer from hair loss, have a receding hairline, or simply want to change their hairstyle without committing to a full wig.
