Closure/Frontal
A lace closure is a small hairpiece, typically 4×4 inches, that is used to close off an install. It is sewn into place and covers a portion of the scalp, usually at the crown or along a parting.
A lace frontal is a larger hairpiece that typically measures 13×4 inches, covering the entire front hairline from ear to ear. It allows for more versatile styling options and a seamless, natural look along the entire hairline.
