A closure is a hairpiece made of lace or silk that’s used to create a natural-looking part and finish for sew-in or wig installations. It typically measures 4x4, 5x5, or 6x6 inches and is placed at the crown of the head to close off the style, giving the illusion of hair growing directly from the scalp.

Closures come in several types — such as middle part, free part, and three-part closures — allowing for versatile styling options. They are ideal for protecting your natural hair, minimizing heat damage, and achieving a seamless, realistic finish.
