A closure is a hair piece that is usually made of lace or silk, although lace is the far more common choice. The hair piece is attached to a cornrow base and secured around the perimeter in order to help protect your hair and improve its look.
The lace closure is smaller than the lace frontal. Closures, for those who are unfamiliar, are special hair units in which individual hair strands are attached (usually hand-tied) to a piece of material, most commonly lace or silk. With partial weaves, an area of the person's hair is left out to cover the tracks sewn down to the rest of the hair.
